Choosing the Best Hard Drive for Price per Terabyte or Gigabyte

One question that storage users who are more concerned about the longevity and future-proofing of their storage ask us is:

“HDD Price per TB (best cost Hard Drives). Is it better to get bigger size drives or smaller drives but more of them to achieve desired storage space?”

Yes, this is a popular question indeed, especially with bigger size hard drives. Those drives tend to be much more expensive per terabyte. It is often cheaper to get an additional drive which is smaller and gain the same total capacity (using two or 3 drives) cheaper.

How to calculate price per GB / TB?

If a 4 TB hard drive (let’s say 4000 MB, for simplicity’s sake) costs $50, how much is that per GB?

4 TB = 4000 GB                  $50 / 4000 GB = 0,0125 $/GB        $0,0125 x 1000 = 12.5 $/TB

How to use the Price per Terabyte Calculator table below?

Below you will find our automatic hard drive price per TB/GB tool, designed to crawl many, MANY different eShops and divide their cost between the available storage. This allows us to rank/list these drives by the largest amount of terabytes youwill get for your money. This list includes popular hard drive manufacturers, such as Seagate, WD and Toshiba, allowing you to ensure that you are getting excellent value for money on your storage, as well as only choosing the most reputable HDD makers in the world. Before you head down there though, take a moment to quick familiarize yourself with a few key factors that will aid you in understanding how to understand what separates one HDD from another

CMR VS SMR HDDs

You can filter CMR drives only if you need better performance (more info). SMR drives are acceptable in RAID1/0 or no raid setup.

Seagate VS WD Hard Drives?

You can go brand specific such as Seagate, WD, and Toshiba. WD might offer things like OptiNAND

Home vs Business Hard Drives, is there a difference?

You can also choose a specific type of drives such as for home use you would use a filter (WD Red or Ironwolf. For business use in a NAS with 8 bays and above filter would look like WD RED Pro or Ironwolf Pro. For enterprise drives, you would choose Exos, HGST, Gold or Ultrastar. For surveillance, you would choose a filter “purple” or “Surveillance”. For simple desktop use you would choose Barracuda, Black or Blue drives. The colours are explained here.

6TB vs 8TB, or 10TB vs 20TB – Which is Best?

You may choose bigger capacity drives if you have fewer drive bays on your NAS. This limits your options for mixing drives smarter way. You might realise that bigger drives but fewer of them can actually be cheaper than smaller drives that use every drive bay.

NOTE – Use the GREEN Bar (ideally for NAS users) to enter your number of bays, RAID failure protection level, budget and whether you want NAS optimized drives only
Note – Use the YELLOW Bar to filter the results by brand, price per TB range, strict capacity and recording method

      373 thoughts on “How to Choose the BEST Value Hard Drive and Best Price per TB – Get it Right, FIRST TIME!”

      1. I started with 6 6TB. Wish I got larger drives. Cheaper per TB and more efficient. That said, I got dual parity for my important files and now 24TB drives for media that I can simply redownload.

      5. Infomation is good but too much fluff in the video instead of providing succinct information. Maybe creating a script would help instead of rambling and repeating the same point again and again?

      9. Virtualised NAS: 2 pools of 4Tb x3 with 60Gb RAM (read cache) + NVMe special device mirror (50Gb) for small blocks (<128k)
        Prioritised sound so they are 5900 vs 7200rpm with rubber tray mounts
        Checkout the Backblaze HDD failure rates (manufacturer, capacity) especially before believing the marketing for _Enterprise_ or _Pro_ drives

      14. A very informative video for sure.
        I’m at the point where I am slowly upgrading my offline nas… my nas is a repurposed PC. It is a repurposed PC with space for 10 spinning rusts (with 5in adapters) and 4 2.5in drives.
        And the kicker, is that it’s all sitting on windows storage spaces.

        My problem is, I can not move to something like truenas or w/e because all my stuff is on storage spaces already. I do not have enough free space to do a local copy, and I couldn’t figure out how I could download from a cloud provider from truenas so I was kind of screwd and had to revert back to windows =(

      15. 1. In a NAS, reliability is #1. These WD Red, Red Pro and WD HC enterprise drives are using helium. 2. Use CMR even up to 24TB sizes. When i bought my WD 10TB HC drives, at that time > 10 TB used SMR. SMR???? don’t rhink about it. #2 warranty. No matter what the price, check that your vendor is a certified vendor or WD may say YOU get no 5yr warranty. THIS IS BIG. Check before you buy. If the price seems to good to be true, duh…avoid these vendors.

      17. Lots of good points for both sides but you didn’t answer the question:”Which is better?” Please make a video with the conclusion and thus the answer. If you don’t have an answer it is just clickbait and you should have chosen a different title.

      22. Another point to consider is when the inevitable drive failure happens…
        How long does it take to rebuild the array?

        My 12TB RAID5 array takes ~23 hours to parity check or rebuild a failed disk.

        The bigger the disks, the longer the rebuild. If your bought a batch of disks from the same retailer at the same time (common thing to do)… will a 2nd disk fail during the rebuild?

        So another tip – buy your disks from different retailers (2 from here, 2 from there kind of strategy)… hopefully you will get disks from different manufacturing lines or at least different batches to reduce the likelihood of simultaneous failures.

      27. I think the “redundancy” feature needs revision; replace it with minimum and maximum number of drives and a tick box if it needs to be an even count for raid 1 or 10.
        When I enter redundancy “1” it just gives me large single drives which is no redundancy, (I actually want raid 1 or raid 10, but a single drive is wrong even for raid 5)

      30. Another specific advantage, related to the advantage of simultaneous reads & writes on multiple disks, is that you can tune a RDBMS so it purposely spreads data across multiple drives and even platters to optimize access, especially for searches.

      31. Sadly I’m seeing this a year late. Anyway, I don’t think you hit reliability as might relate to density. I’ve wondered if an ultra-high-density drive can really and consistently have as few errors as lower-density drives, and if it is much more sensitive to movement and shock.

All the drives started failing close to each other. Next nas I made sure had a mix of different brands, different styles, mix of new and used. That should spread out the failures to different times

      35. ???? Key points for quick navigation:

        00:17 *???? Enterprise-grade hard drives can sometimes be cheaper than pro series drives despite better performance and durability.*
        00:45 *???? Pro series drives often have lower performance, durability, and sustained performance compared to enterprise drives.*
        01:14 *???? Examples show enterprise drives often cheaper, e.g., 20TB WD UltraStar at £394 vs. WD Red Pro at £469.*
        03:22 *???? Pro series drives are subject to dynamic pricing based on demand and popularity of certain capacities.*
        04:44 *???? Enterprise drives’ price per terabyte tends to decrease with higher capacities, unlike pro series.*
        05:55 *???? Bulk purchasing by data centers leads to lower prices for enterprise drives due to high volume orders.*
        08:41 *???? Enterprise drives are noisier and more power-hungry, designed for sustained industrial use, contributing to their cost efficiency.*
        09:51 *⚙️ Pro series drives are quieter and consume less power, making them more appealing for home users despite higher prices.*

      36. Reason 5 : they may sell your refurbished prefail drive and pretend they are new ! When you buy an enterprise drive : CHECK your warranty ! Last 2 exos drive i bought as “new” felt like a scam. First one was reading thousand of hours of powered-on time on smart data and an unusually large number of recorded correctible error. When i plugged it in, it was not blank, there was an empty partition table. When you type the warranty number on seagate website, it was showing that the drive was almost 2 years old and warranty was not provided by seagate. Probably not seagate fault but a scammy seller for sure.
        A second exos drive i bought as new, appeared as new with clean smart data, but i discovered after that warranty was unsupported from seagate. So i’m pretty sure i got a recertified one instead of a new one.
        I’m unconfortable buying more because if the uncertainty. I had a few drive failure before but never bothered checking the warranty before it was too late, now i’m wondering if they were failing refurbished drives. There are many good price on them (france/europe), but I would be willing to pay a bit more to be 100% sure that the seller was not lying about providing new drives.
        If you have recent exos seagate drives, go to seagate warranty page NOW and type the serial number (written on the drive label or just display it in your OS without opening your case).

      38. More drives is always better. If you have one disk drive, failure of that one drive and you could loose everything. With more drives, you can run a raid array. With options for mirrors drives. Options to strip across drives for incredible speed. Or data protection using a drive for bit checking to ensure data stays intact. Just swap out the bad drive. And then the ultimate, use them all together. Speed, reliability. So many options. More is always better.

      41. Also remember: an active raid is not a permanent backup solution, it’s a stop-gap. You should always do regular backups to an offline media as well. I suggest a raid 5/6 for active use and backups then a mirrored external for offline. backups.

      43. The “not all eggs in one basket” is a bad figure for RAID5. Speaking from probability of losing your data, using LESS drives is better. Let’s say the drive failure rate is 3% per year.

        – 2×6 TB RAID1: probability of losing ALL data (2 drives fail same year) = 0.03 * 0.03 = 0.09% per year
        – 4×2 TB RAID5: probability of losing ALL data (2 drives failure plus 3 drives failure plus 4 drives) = 0.518 % per year

        so the RAID1 is A LOT safer BECAUSE it’s using a double safe basket instead of multiple baskets that are connected and ALL fail if 2+ fail

      49. I prefer drives under 4TB as I find them to be more bulletproof. Bigger video and game files as well as AI models have caused me to now need large capacity drives. I been on a computer since DOS. My first PC had a 100MB IDE drive. I used that drive till IDE was fazed out and SATA became the standard. It never died nor slowed down. But it did sound like the Predator from the movie. I stopped using it cause IDE was just too slow. I am 40 years old and I have drives that I had when I was a teenager that still work fine today. The one that runs my pfSense is a 2.5 inch that has been in a laptop for about 6 years till it went in my Desktop for extra storage for about another 5 years and now runs my firewall. Its the only old drive I have that clicks. Been clicking for years now but will not die. But every singe 4TB or larger drive I get will need to be replaced at some point cause they are sensitive like lil girls.

        Vibration or noise or impact or temps or looking at it too long will break it. I have spare large drives just in my closet. No small drives cause they just won’t stop. That 2.5 120GB has been in bumpy cars, dropped 100’s of times, bumped into, ran sitting upright, ran upside down, sideways, slanted, its older than some peoples children, and still clicks along. Its seen soo many video drivers, windows updates and PornHub. But 4TB and up…a loud noise might startle the thing and make it slap its forehead with the back of its hand as it faints. You gotta wake it back up in the controller. Shaking a grown man and he will most likely survive. Don’t do that with a baby. But HDD’s is different. You can shake the baby HDD’s but if you shake the big grown HDD’s they are dead dead dead. We are at a age now where files are big now so I am building out a server rack using large HDD’s not because I need a server rack but because the server rack needs a safe place to even be a server or NAS like Hollywood. PC’s are built different. They will save mkv’s and load steam in the streets of Brooklyn even after being dropped violently because a bee flew in your face and swatting at it and missing the bee made you smack the PC on to the ground. Them small capacity drives are built like 50 Cent

      51. IME, few motherboards have more than 8 sata ports, and most around 4. It’s definitely a better idea to use the largest drives available. Also, I don’t trust these NAS. I take something with ECC RAM and put linux on it, currently btrfs raid-1 with triple redundancy. So it can lose up to 3 drives and not lose data. I trust the code and security updates from Debian way over those a NAS gets.
        I play with datasets for AI, and have accumulated over 72 TB of data, half of which is probably not essential, but makes reproducibility easier.

      54. Gr9 vid man! Appreciate you going thru all of the various different perspectives and angles of all of this info! My plan is 6 drives, raid 6, at least 2 systems, 1 system as backup, 1 system live, large format drives, not going to be cheap, but want the redundancy of raid and mirror, allowing up to 2 drive failures at one time. Most likely just Truenas scale at this point. Subbed and liked! Keep up the great work!

      59. Is it possible to set up my NAS to copy over from a HDD to SSD and paste back on shutdown? Or just work in parallel with the SSD as a main refference and buffer stack any writes that the HDD can’t keep up. I preordered myself a 6bay + 2 m.2 Ugreen NAS. I worry that the biggest size SSDs are 8TB, but I could add two and have 16TB, somehow copy that to a HDD. And any less important data on normal HDDS

      60. He’s math aint mathing you used 3 6TB’s when you need 4, 2 6TBs for 12TBs and need 2 6TBs for the extra 12TBs for redundancy.

        So here’s the math you mess up on 1 6TB=158 1 12TB=258 right so 4 6TB=632 and 2 12TB=516 so you are spending 116$ more and I guess you didn’t see you have 1 lass drive when you’re doing this or YOU are trying to miss lead people on what you are doing here.

      61. This isn’t strictly relevant to this specific video but I’m asking advice I’ve been given the task of assembling a moderately large NAS for a small company.
        I’ve decided I am going to include cache but it’s the type to get I’m confused by.
        It happens to be a Synology NAS I’ve gone for, and I noticed that specific types of M.2 Sara or nvme are recommended. It basically narrowed it down to WD Red, FireCuda 520 and Synolgy’s own 400 or 800Gb Nvme.
        My initial reflex was that it was probably a good idea to go for Synology as it’s the same make as the enclosure but 400Gb of Synology SNV3410 Cache is about twice as expensive as 1Tb of WD Red nvme.
        Why is this and is there anything that justifies this price difference?

        I recently had a pro drive frail (when I say fail I mean the cat knocked it off the shelf) and luckily it was under warranty, just.

        Since then I am looking at enterprise drives as they come with a longer warranty.

      63. This is sort of a strange take imo… it isolates an issue that cannot really be isolated like that in reality. There are too many variables to take every factor in a generalistic way and have it be useful.
        So in a way you have to establish a sort of brake point – above X cost the value of data isn’t enough to justify the cost of keeping it. What I mean is that in principle you should have a NAS by a different vendor using different drives in a different location, to your primary. Realistically most peoples data is not “worth” that kind of solution run privately. So the most important thing really is to determine what data is worth enough effort to really make sure it isn’t lost. Back that up across several solutions. Like USB sticks etc. The rest? Yolo 😉
        If you want to mess with this stuff as a hobby, all the power to you, but do back the important stuff up some other way too. Preferably “off site” however you prefer to do that.

      65. Bigger drives are better. But if the data is important to you, the cheapest way (if it is not for professional needs), get the biggest drive vs price you need, and have an extra one as backup you dont use except for backup. Keep that backup away from power in some storage shelves or so. Hdd you dont use last very long. Had a drive from 10 years ago that I almost never used and put it in ‘cold’ storage, so unplugged in a shelves, and worked like a Sharm.

      66. I’ll put this out there for anyone to answer – I contacted MSI to ask them and the reply was basically “No Idea – let us know how you get on”. I have an MSI Tomahawk Max II Mobo, running a 5600X and 32GB DDR4 3200mhz. Because I have a 4x Nvme 2TB boot, I only have 4 SATA drives available (I don’t bother with a DVD). I have added a 7 port USB 3.2 card. So I’m running about 72-76TB of drives. I want to expand that a lot. The internals are only 500GB – I want to take them to 18TB. Will my chipset support that? Even MSI said “Meh – Dunno”. Has anyone here done it? Its a very expensive experiment if it fails….

      71. I realize that bigger ‘pro’ drive would be more reliable, NAS class/designed to be better, that’s why their also more expensive to the identical desktop version… BUT to make these lager capacity cheaper, one way *would* be to make them in desktop class and loose that extra reliability you only pay on ‘pro’

        Plus, to limit higher capacity to RED drives etc, manufactures get more money, and users don;t have a choice if its not there.

      72. Per gig is cheap now-a-days. However, i don’t think i should admit i still use Barracuda desktop drives in my NAS…

        Their cheap, compared to RED drives and IronWolf.. Besides,from past experiences, they ‘whine’ allot in idle mode… Could of just been bad drive, but i doubt. These were 4TB drives

        Also, power-saving can make up the difference between buying big drives… The presumption your making is NAS’s are designed to be on all the time and active all the time, which is not always true. There is always going sections of ‘idle’, time, (particularly after midnight),. If you have Scheduled backups going on a QNAP, your gonna allow a few hour either way before the next starts to prevent possible increased failure. In that time space, the dives will spin down after 30 mins (usually) thus saving power. If you work that over a given year, that’s still a bit of energy saved right there.

      74. Honestly I just have a bunch of 4tb red drives (every seagate I have ever bought failed within a year.. all of them..) My reasoning is its easier to replace a 4tb drive than an 18tb drive. Both in cost and in time. If I fail on a rebuild then I only loose 4tb of data. (I use unraid) I only backup what I can’t get back (pictures, home movies, etc. I can always re rip my dvds and such. 3-2-1 can get expensive otherwise. Especially with larger drives.

        The little nas boxes seem pretty neat but frankly an old pc with an hba card is all you need. Buy unraid once (or use truenas, openmediavault, linux, whatever you prefer) works. I prefer unraid because of the way it works. Even if you fail on a rebuild you only loose whats on the failed drive. With raid you loose the whole pool. With nas boxes your upgrade path is kinda expensive. With other options you can just use your old pc when you upgrade.

        My 2 cents worth. A lot of options. Depends on risk, time, and finances. Everyone’s mileage will vary.

The Ceramic Memory Drives will be integrating over the next 5-10 years and the HDD will be as useless as the VHS and 8track tapes. So… no need to currently buy anything bigger than 200% of your needs, as you will be replacing them before you fill them.

        Crib the storage perspective, of course, not the noise/power consumption.
        Of course, with larger drives one should be very sure of the backups. And preferably use 2-disk redundancy to boot. It may be also result in higher ram usage.

      83. Select drives based on workload and never mix workloads.

        If you’re recording surveillance 24/7 don’t mix that with other data. The surveillance activity is going to wear out drives faster. Putting other data into that mix is putting that data a risk.

        So you might need bigger drives for surveillance and maybe smaller drives for your other stuff. Create separate arrays to separate the workloads and buy drives that make sense for each workload.

You talk about the possible more possible points of failure.. but you miss the big point with Raid 5 vs Raid 1… raid 1, if one drive dies.. you take it out.. order a new one.. re-raid it when you get it.. with raid 5.. when one fails.. you have to get another drive and rebuild it.. b ut while that is going on.. the entire raid is OFFLINE.. so I normally recommend.. if you RAID 5.. order a spare to minimize the downtime…

      87. Here is how I do it: get the price divided by total capacity to get $/TB. That is the true cost of your storage. Then you can compare apple to apple on all of your drive options and pick the cheapest one.

        Just note that there is a trade off. The more drives you have, the more power it is going to draw and the more points of failures there are in your system.

      91. I feel like power consumption… isn’t a factor. You’re going to consume more power. You should expect that.

        Also noise… isn’t a factor. HDDs make noise. If you don’t want noise, don’t get HDDs.

        Here are my take-aways:

        1. Don’t just get 2 drives. Because you’ll end up using one for parity only and waste the space you could use.

        2. Get 4-5 smaller drives at once so you can benefit from the performance boost. This also ensures you can have more useable space over all.

        Unless you have the cash to fill out 4-5 18TB drives in your NAS, just get smaller drives. Then you can have better performance and more redundancy.

        If you didn’t want high power consumption and lots of noise, you shouldn’t be buying a NAS and filling it full of HDDs.

      107. Having not watched the video… both have their benefits and drawbacks.

        Benefits:
        More means higher throughput can be achieved and higher levels of redundancy can be gained making the setup more resilient when it comes to disk failure.
        Bigger means less power draw, less vibrations and less potential heat, less physical space used and more capacity.

        Drawbacks:
        More disks is more power draw, more vibrations more heat production and more physical space used. With the added redundancy comes less capacity as the redundancy means disks are there just to cover the situation where one or potentially more disks fail protecting you from data loss in those cases.
        Bigger disks means less options for redundancy as you have less individual disks, less theoretical throughput and often higher cost because even though the cost per GB drops the amount of GB’s per disk is significantly higher.

        In the end it does not matter much which one you pick as long as you first take some time and think about what your goal is with the setup maximum redundancy and not to concerned about max capacity well more disks is better. Maximum capacity and not to concerned about the data’s longevity less big disks is the best option. If your chosen NAS enclosure allows for more disks than you are currently using then less but bigger might also be a good option as it will allow you to grow the storage capacity over time.

      109. OK Typed up a long post and then lost it all… So here is a short version.

        Check the manufacturers HCL (hardware compatibility list) before buying drives. And if you don’t find a drive of the capacity you want then consider if it’s worth the risk. RAID controllers can be real finicky about drives.

        You may feel SATA and SAS is mature tech and there should be no compatibility problems, but there are and there will be more. I’ve worked with (from memory) Adaptec, Areca, Raidcore, 3Ware and LSI. Sometimes the compatibility problems are blatantly obvious, but sometimes they are a creeping problem that takes time to develop, and they don’t get better with time. Sometimes a firmware upgrade of the drives or the controller can help, but there’s no guarantee that either is coming if you start out with incompatible hardware.

        Also stress test the arrays before your start using them. Run every storage test you can think of on them, and then try some more. Check the RAID logs and take note of any warnings. You don’t want warnings! Not even the non critical kind. Make sure there’s as little vibrations as possible. Vibrations can play havoc with RAID arrays even if they are not strong enough to cause a head crash.

        Also don’t use Shingled magnetic hard drives. They are a pain when used for RAID.

        Temperature! A interesting paper published by a storage company probably a decade ago showed that the ideal running temp for HDD’s seems to be between 35 and 45 °C. Higher or lower temperatures showed increased failure rate. But don’t take this as gospel. However we do know that high temperatures are bad in general, and 40°C is a quite easy target for HDD’s.

      110. I don’t have that much data, so I end up just refreshing 2.5″ hdd every few years, and use the surviving older one as redundancy backup. as time goes on, newer drive will be cheaper with more tb, so if I don’t need those 16tb at once right now, I can just buy 4, 5, 5, 6 over the years whenever I need one. Currently have 500gb, 750gb, 1tb (dead), 2tb, 4tb, 4tb, 5tb, 1tb sata ssd, 2tb nvme

        Sure multiple points of failure, but at the same time it’s not all eggs in one basket. I did once have 1tb hdd when it was huge in 2009, backup all my files, then trip on the power cable, making the drive dead, with all the 1tb data I just sorted. So nowI list down list of file I have in an excel sheet in gdrive. so if one broke down, I know exactly what data it stored. Especially if I have 1 hdd for 1 tipe of stuff. that one is for x, this one for y, this one for z. so I won’t need to find z in x.

        Personal use 20tb should be more than suffice. which is probably 4x5tb or 5×4 tb. 450-500 usd probably. All my photos from 2010 is only around 400gb jpg. and since current hdds are 4-5tb or so, yea I can manage to save more copies in more drives.

      113. If you have seriously important data don’t use a NAS use a SAN, lots of drives only generally gives a performance increase only for reading not writing, RAID on NAS devices usually has some restrictions based on implementation of the standards of the supplier vs on board raid provided by server manufacturers. NAS providers are great at vendor lock-in. Also make sure you buy drives compatible with the NAS as they don’t cover warranty issues otherwise. Generally pro series drives offer 5year warranty non pro are 2-3 years

      114. huge enterprise drives can go 300mb/s sequential while a 4 or 6tb drive usually cant even hit 200mb/s especially if they’re 5400rpm so fewer disks can be as fast depending on the size difference. Also, the power use is substantial when using more disks. disk power usage can be more than the rest of the entire system combined when talking about 10+ disks

      117. clip starts after 1 minute intro. In 1 minute I explain the easy facts 😉
        More drives: good for raid level 5 or higher. Where raid5 needs at least 3 disks. In case you need a specific raid level, you need the least amount of disks.
        More drives: eventually more cache if you use drive cache. Depends on drives.
        More drives: more performance if your controller is still not on its limit.
        More drives: can increase performance, if the blocks you need are on different drives.
        More TB: less power consumption compared to the same storage with more drives.
        More TB: higher density = faster access (compared 1 disk with 1 disk, not the raid in summary)
        More TB: overall costs could decrease (smaller NAS, maybe more TB per $$)

      118. I use 8 x 8tb as standard in my 8 bay nas’s, JBOD. Reason is, I use a 2nd and 3rd nas as backups, and if a drive fails I just copy the data onto its replacement, that way I just keep 1 nas running, otherwise 2 would be on all the time, I do a backup using goodsync once or twice a month, I tried synolgys drive sync, too automatic. I like the control of goodsync.

      119. Very short version… go for more drives. More smaller drives usually work faster AND they make less noise. My advise would be never to buy drive bigger than 8TB, larger drives come with a big drawback of noise. Also using more smaller drives and a drive failes its cheaper to replace and faster to rebuild.

(Noise won’t make thát much difference for me, but it is in my room.) My two goals of the NAS are: storage (of currently about 6 TB video + 1 TB backup history), and connecting my LG C2 (OLED 4K 48″ 120 Hz) TV to it to watch videos (often 4K) from it?

      122. To what extent can you mix and match drives in something like a Synology, QNAP or Asustor system? I have only WD Reds because my original NAS was a WD. I was wondering whether I can use Seagates if one fails. I was also wondering a switch to a bigger drive would work. Say I have four 8TB drives and I replace one with a 12 or a 14. Does that work? What impact is it likely to have on performance?

      123. I had a slightly different experience from what is expressed here, though I’m not casting any doubt on the validity of the information. I have a Nimbustor 4, populated with 4x8TB, for 24TB of storage.

        I went for 8TB because, at the time, it represented the best bang-for-buck and gave me a total capacity (24TB in RAID 5) that I was unlikely to exceed for quite a while.

        The NAS itself represented the best box I could justify. Being four bay, it also gave me the opportunity to spread my expenses over a longer period.

        When I originally set it up, it had two drives in it. It was kind of noisy but no more than I expected. When I added a third drive, the noise and amount of disc access was much greater than it had been.

        Recently I upgraded to 8GB of RAM and added a fourth drive. The first thing I noticed was that the overall noise is far less than it was with three drives and almost certainly lower than it was with two drives. In fact, it’s got to the point where I rarely hear it.

        This probably won’t be most people’s experience but it seems to me that either by luck or design, I ended up in a sweet spot. I can’t explain it but I can hazard a guess that this is the kind of setup the designers envisioned…?

      125. I think a lot of the enterprise drives that trickle into the consumer market can also tend to be in batches, i.e. leftovers, overruns, supplier cleanouts from warranty stock, etc. There are deals to be found on them often, especially the size down and the two size down slots. When they go out of vogue they get dumped like hot potatoes from the bigger distributors (whatever they don’t clear from their main channels). Newegg, Amazon and any of the other physical storage connected resellers have clear advantages here as well as they get liquidated and surplus items as part of their business model.

      150. As an Arch Linux user, I was torn between buying an expensive (new) tiny RAID machine with 4 x new HDD’s or using an old (but free) monstrous 12 bay Supermicro server with 12 (free) smaller HDD’s.

        Decided to go the Supermicro route. Have to admit, I’m way in above my head on this and have been dragging my feet for nearly two years now. In the end, I’ve decided that any form of RAID like setup is not for me. Don’t want to pay electricity (UK prices) on a server running 24/7. The beast can sit in the corner and be booted up once a week, whereupon I’ll do identical rsync (ext4) backups to two of the four nodes. Then following month do the same to the other two nodes. If I have a week when something of critical importance is created, I’ll rsync immediately. Also like the idea of each backup being completely isolated from the others.

        I know my PC HDD will one day fail. However, given a choice between losing a few days of data or paying 24/7 electricity for RAID… I’m prepared to accept the former.

        Thing is, I’ve never heard of anyone doing this with a four node machine, so maybe there’s a good reason not to. I like the idea of the sever being extremely heavy, as it’s less likely a drug addled thief would be able to move it, or even realize the drive bays are removable. Always thought those tiny RAID machines were too easy to tuck under your arm and walk away with. In fact, I might even bolt the thing down, as right now it sits on a table.

        Could’ve gone with 4 x HDD’s and backing up via USB. However, that’s back to the hassle of pulling them out from a hiding place and connecting all those wires up. Plus, I’d need to buy large expensive HDD’s. Yep, I just like having four sets of backups.

        Yes, fire/flood is a possibility, but still have a cloud backup for all essential documents. Like I said, I ain’t no expert or computer geek. Maybe it’s a daft thing to even consider doing…

      151. In 2004 I had 9 Seagate hard drives fail in a 2 week period and they were sequential serial numbers. When I contacted them about a possible issue with that batch they spewed out the corporate boiler plate response saying that wasn’t the case and that their hard drives were of very high quality blah blah blah. I asked for new replacements rather than refurbished ones but they wouldn’t do that either. I’ve never sold another Seagate drive since. I doubt the few thousand drives I’ve sold over the years that weren’t Seagate are missed by them but I also never recommend Seagate because of their piss poor customer service.

      157. IF I “HAVE TO” BUY A BRANDED NAS BOX, I’d spend my money on the biggest NAS with the max # of BAYS possible. Cuz you can always buy cheap smaller drives at first, but if you get a small NAS and used up all your bays from the begining it won’t grow more bays in the future and expanding more capacity means you have to discard your smaller drives, and that is a drive doing nothing loosing it’s value as redundancy.

        The question of more hdd or Bigger hdd its a wrong question. Why? because the purpose of a hdd is to hold data. So data security always comes first.
        Product like 2 bays NAS are pointless, you can achieve that with any old computer or laptop laying around your house, hook it up to you network and you have a raid 1 (minimum) NAS, the rest is just SOFTWARE, heck if you like Synology that much you can use XPenology which is a hacked version DSM 6.2 and the new DSM 7.0 that can be installed in any computer. And if you think well my old computer consume a lot of WATT to be an Always on NAS, then find out the socket of your motherboard and buy the most efficient CPU on ebay. Like, I have an old i7 90W cpu, then get an i5 35W chip for $20 and it will be almost as fast as the fastest Synology box.

        Then what is the appropiate rule to build a NAS. It’s pretty simple actually… you build it with the capacity you’ll need. A good rule of thumb is aggregate all your current storage cap in your house and multiply by 2 (chances are it took you years to fill them up). Most people without NAS, they won’t reach 14TB.
        And this is how data centers are built, they buy by capacity and not expandability.
        Second thing you’ll need to do is calculate how many disk you are willing to distribuite those “14TB”, always remember the more the better, cuz you will have more redundancy.
        In my case I would go for used SAS drives on ebay, for one they are all 100% enterprise drives, and are 1/2 the price of SATA drives with the same Capacity, but that also means you need to build your NAS with a SAS backplane and a SAS HBA in mind. ie I bought 3 Dells R730 XD with 24 2.5″ bays, 24 cores, 256Gb ram ECC and it includes 24x 2.5″ inch 600GB 10k rpm sas drives. For only $900 ea. I bet you can get waaaay lower price if you go for r620
        Now you can also get a r730 same specs but with 12x 3.5″ bays, there is one that comes with 12x 3TBs SAS drives a total of 36TB for $1400. Synology 12 bays costs $3000 and it doesn’t come with disks. Booooo
        If you go to ebay, you can see SAS 3TB goes for as low as $15 ea and buy in bulk I found a 5x 3TB for $30 total LOL. Oh! and it’s free return, couple years more 6TB will be at the same price point.
        And almost forgot, you can switch to SATA drive when you like. Cuz SAS hba with SAS backplane can take SAS drives AND Sata drives. Unlike most Synology NAS only accept SATA drives.

        Of course power consumption is a problem but it’s like $25/mo I would gladly pay (cancelled Netflix and Disney Plus LoL), cuz you are dealing with a real server not only you learn new skills, and all the parts are super cheap. And you can always expand your server capabilities. Synology is moving to 2.5Gb and 10Gb as PREMIUM stuff… heck I’ve been running 10Gb like a decade ago. I moved to 100Gbps, not long ago, that’s 10GB/s!!! The cards costs like $150 ea and the switch costs around $600 for 32x ports of 100Gps, yes 32 ports. I moved all my nvme to boost the server storage, and all my terminals are all diskless because booting from network is almost as fast as having a local Gen3 nvme, and not to mention all the VMs and Dockers you can run.

You make a good point about balancing out between the cost of NAS system and the actual storage. One option for anyone starting out could be to go for a smaller storage and then buy more/bigger HDD as the data grows and HDDs become more affordable in future, while investing in a NAS with more bays for future-proofing if really necessary. That also means hopefully sticking with the NAS with more bays for a longer time, given the initial cost.

Any important data still needs a backup, RAID5/6 yes can increase read/write speeds but its really about redundancy (meaning uptime), businesses need to maintain uptime but not home PC users unless Home users are hosting web, file, plex servers for others offsite to access.

The 920 CPU is about 50% faster, but the 1819+ had 6x HDDs, and i used the other 2 bays to run normal SATA SSDs as a RAID 0 cache, since the add on card for the 1819+ is really pricey for what it is. I ran PLEX on both and initially it felt like the 920+ was slower and stuttered more with larger files, however now there doesnt seem to be much of a difference. Hardly a scientific test but this is an interesting question. Not sure how to test it scientifically.

      182. You missed one point. Kinda. It falls in line with the performance aspect. the larger the drive the longer the rebuild takes on a failed drive. So a 4 or 6TB drive, depending on how full the prior drive was may take 3-8 hours depending on the speed of your system / controller. But a 20TB drive could very well take 24+ hours which in turn leaves your array in a vulnerable state for a second failure. BTW this is why NO ONE should be using RAID5 anymore. The happy medium for me is somewhere between 10TB-16TB drives. They offer larger storage, but with a reasonable rebuild time.

      190. You don’t touch on the fact more drives you are using less data per drive at any write or read.

        If you have 2 large mirrored drives, 100% of the data is processed through each of the drives. If you were to have the same capacity over 8 drives, the actual throughput is divided by 1/8th per drive. If you look at data loads of 300tb per year with an MTBF of 1,000,000 hours, the raid with 8 drives will last 8x longer.

        such as, if you have 4 SATA ports and you used 2, then you will soon realize if you buy too many low-volume hard disks, you will soon be out of IO to let you upgrade in the future

      197. I’ve got this idea recently.. In theory, what about using classic non-NAS type 2,5″ SATA SSD’s? For example four 2TB SSD’s in RAID 5? I know, it’s more expensive. But it’s silent, less power consumption and if I would have money for it? Just for home using, not really too much transfering data and important data will be backed up to external drive too. Is it there some statistics or something? What’s yours opinions guys? I have few data SSD’s in pc for long long time using by daily basis and they are immortal.

      199. Maybe I’m on drugs or something because no one else is commenting on this, but in regards to the first segement “More HDDs Can Be Cheaper…”, your math seems all wrong. If a 18TB costs $389 and 3 6TB cost $158 each the total is $474. The 1 18TB drive is substantially cheaper. It seems to always be cheaper to buy 1 large drive than it is to buy 2 or more smaller drives to reach the same capacity. The one exception seems to be the 22TB RED drive. While its true that the TB per dollar increases the smaller the drive is, it doesn’t do so nearly fast enough to make buying multiple smaller drives worth it.

      200. For most home users, bottom-line .. use RAID 1. What you’re not telling the people is the difficulties in rebuilding a failed multi-disk RAID e.g. 5,6,10.

        Multi-disk RAID 5,6,10,etc is when you need large storage capacities exceeding a single disk capacity. For example, large storage banks of video, photography, workgroups, etc.

      201. More drives is more performance is quicker to spin down is less power used. More competent nas can run server tasks or wake on lan or….using less power in total than a smaller nas can in your total setup.
        Large drives take to long to rebuild to be used in anything less then raid 6
        I rather have more points of failure then 2 drives that are the same type and age and then pray for 24 hours that the remaining drive works to rebuild the raid 1 set.
        And ofcourse raid isn’t backup, always make back ups because if it goes terrible wrong you can lose all your data no matter what setup you have. A fire or flood doesn’t care about your drive size.
        If you don’t put the nas in a place where noise isn’t a problem, use SSD if you use your nas constantly or time it so the drives sleep during the day.

      205. What happens if one buys enterprise class hard drives because of the lower price for external storage backup? You plug them once a month in on a SATA docking, update the backup and the let them sit for a month. By logic, being them more rugged they should last fine, is that so? I never understood if being engineered for 24/7 becomes a problem when the drive is used only occasionally

      215. It is important to also consider rebuild and restore performance. With a larger number of drives running RAID 5 or 6 there is a significant difference in rebuild time compared to rebuilding a mirrored array. Also there is a difference yet again when you compare something like a RAID 10 to a pool of mirrors instead. In the case of RAID 5, 50, 6, 60 and 10 your backup will be of the entire array. In the event that data loss actually occurs and you must restore from backup you are talking about restoring the entire size of the array that was lost. However, when using pools instead you can elect to restore only the data from the underline RAID 1, 5 or 6 that you lost. These are all important factors to consider when selecting how you want to build out your storage array.

        Also I should mention that if you are going with a lot of drives it is also possible to hybrid nest the arrays in such a way as to maximize performance while also minimizing your restore from backup time and risk of inaccessible data. For example you could take two drives and place them in a RAID 0 then take two more drives and place them in a different RAID 0. Then you take those two RAID 0 arrays and Mirror them together. You create sets of 4 drives in this method that you then pool together. The obvious con to this is that you would ideally add sets of 4 drives at a time to your pool.

      218. The biggest point you’ve missed is that the best way to shop us to first identify your risk tolerance, and then identify the workload needs, and buy either the largest drives you can afford that give you more redundancy than you think you, need or the fastest drives you can afford that give you more iops than you think you need. Your video also completely neglected iops, focusing on sequential io and capacity. Even just adding a small nvme mirrored cache device can turn a large disk pool into a virtualization and game storage powerhouse. Imagine what you could do with all-flash

        Cheaper long term to buy the biggest NAS with biggest hdd’s, Otherwise you will run out of space and cost you more to replace all those smaller hdd’s or smaller NAS.
        Not really worth it to buy the expansion unit only to fill it with more smaller drives.
        Made that mistake with my first NAS, 5 bay and only filled it with 3x8TB (1 for redundancy) drives adding another 2 later on.
        Thought I was being smart and saving money, Filled it after 3 years, I regret not going for 16TB drives at the start and would have lasted twice the time 6 or more years.

        The comparison of a small size storage ( smaller than 20 TB ) I think was the focus of the video and not larger size storage (35+ TB storage sizes.

        I hope you will be able and willing to answer my question. I have a DS218+ with 2 8TB seagate iron wolf harddrives. I want to have an upgrade so I’m buying a DS420+ nas and 2 18TB seagate iron wolf harddrives. My plan is to replace my 2bay synology to the new 4bay synology and I want to know if I can just put the 2 8TB drives into the new synology and then also add the 2 new 18TB drive in bay 3 and 4..

        I want all of them to be configured with SHR and the 2 8TB drives are already in SHR. According to the synology website (the nas RAID calculater) it tells me that with my setup (2x 8Tb and 2x 18TB) I should get 32TB available space and 16TB Protection.

        So.. can I just take the 2 older 8TB drives (in SHR) out of my 2bay synology and put them together with the 2 18Tb drives into the new 4 bay synology without losing my data or without having to figure out a way to transfer the data off the drives first.. I do not have the external drive space to temporary store 8Tb worth of data. I don’t really care all that much about any settings from my old nas, all I want is to keep all my own data safe when transferring to the new nas.

      253. The required amount of redundancy depends on how you plan to use the storage. If the NAS is the primary storage, then redundancy is very important. If the NAS is backing up primary storage on other computers, then RAID might be less critical for some people. The other consideration is point in time, or off-line, copies. If you have a fire or a ransomware attack, it might take out the whole NAS. Therefore, you need protected offline copies. That means maybe double or even more storage. How should we provide that? Does that remove the need for redundancy in the NAS?

Compare prices for some sample configurations with the same amount of usable storage.

      263. I think the bit you didn’t really focus on when comparing two 18TB drives vs 5 smaller drives was you dropped from a RAID Mirror to a RAID Array. That is often a big performance drop. Also replacing & rebuilding a RAID 1 mirror is faster. And if you lose both, and want to pay someone to do disk plater recovery, the probability of retrieving usage data, drops significantly when they need to reconstruct the data off multiple drives.
        When might you lose both RAID 1 drives simultaneously? Domestic: Voltage spike/lightning. Commercial: Some idiot unscrews the wrong thing & drops all disks on the floor.

        The noise is a legitimate concern, but I think for most people the best solution is to try and have a wiring closet / server room type setup and put it in there where you won’t really hear it. Of course, the problem with that is that the house basically needs wired for ethernet with a patch panel. I wish I had that.

      268. There´s a interesting point to consider the multiple disk use. The SATA saturation (or other conector). If you are using the 10 Gb connector and/or VMs and docker applications.You can saturate the data bus with to much IO, exceding the SATA read/write capacity, and depending of biggest caches in SSD. And surprise, more probability of failure via hard/soft or energy. With multiple smaller disks more data can be read and write. The trick is what is the size of storage that you need and what size of NAS (slots) you have (including the extenders).

      276. Having just replaced or added HDD’s to both my 4 bay Synology and my 4 bay QNAP, my next NAS purchase to replace one of these will be an 8 bay. And I’ll install 3 larger HDD’s in RAID 5 or Synology Hybrid RAID and add new and larger drives as the need arises and prices fall. The worst thing about smaller NAS is the cost of pulling out perfect good, decent sized HDD’s because you need to replace them with larger drives. This is especially problematic with QNAP as you need to have all drives be the same size. With Synology’s SHR, drive sizes can be mixed ( although even that is not perfect). The extra cost of an 8 bay vs a 4 bay is easily saved by the ability to continue to use my older, smaller HDD’s. Don’t be deterred by up front costs; look at longer term use and future purchases and redundancies.

        in case of business you need IOPs and you do not care about noise because you have a datacenter (for small that it can be), so smaller disks in higher number give you better performance anche noise means Enterprse disks which have higher number of TB/year. at the same time as enterprise, for small that you can be, you should implement the 3-2-1 backup rules or at least having a backup site. the additional point is having a redundant power supply on your NAS.
        for the remaining part, what you said is perfect for a consumer site.

        We often opt for a wee bit smaller but more drives. As we always have 2x cold standby HD’s (thus unused!) near the NAS.
        But more drives also means more power-use as you already indicated and also more heat. (more cooling might be needed)
        Business-wide you should replace your HD’s every 3 years (5 years, max) but for the average user at home, you replace when really needed. (or after 10 years?)
        To reduce risks, we also opt for multiple NAS. As a NAS may fail (power-supply, firmware-upgrade, bricking)
        With larger drives the rebuilding of the RAID also may take longer., when something does go wrong.
        BTW, also worth noting, the weight of the NAS might become significantly higher when you are using more drives (noticeable after 8x drives IMHO)
        Generally speaking, the 6TB and lower are robusts as rocks (longevity), 8TB to 10TB are often the sweet-spot for pricing in my experiences.
        Word of advice: buy as many drives as can fit in your NAS as down the line by the time you want to buy additional drives, the manufacturer may have moved-on to newer models..

      293. Factoring in that I had a stack of unused drives already, my first Synology was a 12 bay. I filled it with 1tb-6tb drives and was golden since that meant I didn’t need to buy drives until I needed more space(which happened, again and again ????)

      294. I think it really depends where you are and what you can get. In some countries, it’s cheaper to get bigger drives and a two bay NAS, where other places, smaller hard drives and a four bay NAS ended up being the better option. I’ve always tackled it as a your-mileage-may-vary scenario.

        Although if you want maximum capacity, a bigger NAS is the way to go.

      297. It is a little painful to see SMR being given an OK for NAS up to 5 bays…. Your 16 April 2020 article seems to contradict this. SMR should not be used in a raid array unless you have a very specific use case. And I thought 8TB and larger Red drives were CMR.

      300. As stated numerous times before – If you are shopping in the “Red Pro” segment, don’t. Get enterprise instead for better price and superior performance. Especially higher capacity variants. WD Gold (btw just the the “civilian” branding of Ultrastar) is too expensive though, so don’t go there.

      302. Robbie, I have a Synology DS-920+ that has 4 x 6 Tb WD Red Plus configured with Synology Hybrid RAID. It’s for home home. I will need to start replacing the drives with something a bit larger – probably around 12 – 16 Tb. The issue is that the old drives run at 5400 RPM and have 64 Mb cache. The new drives are 7200 RPM with 256 to 512 Mb cache. Are these differences likely to create much in the way of problems for me ? Not optimizing / maximizing throughput and access times are not a huge issue ; I’m more concerned about reliability and longevity.

      304. Well I like to exos drive simply because it’s just faster on all accounts and once the drives that hit above 500 GB traditional I just too freaking slow. Just doing a scan takes all the two days only 500 GB on a traditional one head drive. I do realize with the exos that with the additional head was going to be extra power usage. Although with the additional heads and lower RPMs they might moderate it

      305. Good timing on this video. I’ve been doing research for months bouncing back and forth between the WD Gold (enterprise) versus the WD Red Pro (Pro level), the pros and cons, speed, etc and the one thing I notice that the Gold is always about 10% less in cost and I couldn’t understand why. Thank you!

      316. What about storage purposes? Everyone talking about SkyHawk as surveillance but doesn’t it also mean it’s best for storage purposes? However, we have to use storage disks time to time make a read from for video, music or pictures etc. Also when it comes to price, Barracuda (ST4000DM004)[price_1889] is 50% more expensive than Skyhawk (ST4000VX007)[price_1271] at the moment. Exos (ST4000NM005A)[price_2084] is also close to Barracuda’s price range, only 9-10% more expensive.

      318. I contacted Toshiba for support questions for their Enterprise Line of HDD. They said they don’t provide support for Enterprise products and asked me to contact my Dealer or enterprise contact.

        Avoid enterprise lineup if you are looking for warranty support.

      319. I was waiting for delivery of WD GOLD 18TB but I cancelled immediately after checking power consumption in idle mode and noise level. In long term some extra Watts convert into some extra money to spend on electricity. Additionally dB level is significantly higher in Gold models in operation mode. 16TB RED PRO has best price per TB for whole lineup. Thank you for this video.

      321. Informative video but in a few places you are not comparing apples to apples. The WD Ultrastar drives are comparable to the WD Gold drives but you were showing them compared to the WD Red drives. The Golds are based on the technology of the Ultrastars and are similar if not identical and both are optimized for both reads and writes although the Ultrastars come in more configurations for Enterprise like SAS instead of SATA, etc than the Gold drives. The Red drives are NAS drives, optimized for reads more than writes. The Purple drives are optimized for Video surveillance so they are better for writing than reading. Also be careful when buying drives to consider not only the interface and optimizations but whether they are OEM vs Retail and the warranties involved. I have bought multiple Ultrastars at significantly cheaper prices than their Gold counterparts so I agree with the point of your video but make sure the features are the same like Helium vs Air, EAMR and other technologies that might differentiate them when determining price and what matters to you.

      323. Its all about speed if your running a buisness who gives a shit if you need to spend a further 5k to get 10gbe with ssd or nvme with 10gbe nas.. Mech drives are 10 year old tech which are ok if you raid them but you need a nas with 5gbe or 10gbe to be serious. Oh look Nas makes 2.5be a standard, like 10 years too late. Ive run mech NAs drives for over 10 years they alway corrupt.. soon as i went sdd or NVme with 500-1000mps zero errors in 3 years.

      326. I’d suppose that the consumer drives are a little costlier to support, since they add on consumer friendly warranties like data rescue and also need to field phone calls for smaller volume purchases (ex. 5 drives vs 50).

      330. I find 10TB drives often cheaper than 8TB and 14TB less than 12TB.
        18TB too occasionally can be found cheaper than 16TB.
        These sizes from I’ve heard are the drives that often use odd number of heads, ie atleast one platter uses only 1 head (often to use up platters that are defective on 1 side).

      331. I just want to chime in on the prices I saw when I was buying 16 TB exos Seagate drives. I spent anywhere from $250 to 230 on five of them. I saw the equivalent Ironwolf drives for $50-80 more. Of course these are all on eBay some of them were either new or open boxed. They’re all still working right now.

      339. Don’t forget, the EXOS is a helium drive too, most Ironwolf Pros floating out there for sale are air drives. You should’ve included Firecuda drives for sure or, at least, dedicate a video to them so you can explain the caching.

      342. I’m a little annoyed the firecuda wasn’t talked about at all. I was also hoping for a little more on the exo series. I’m looking for a large volume hard drive for multiple uses. Movies, gaming, development.m, etc. I want to get the best performance for my dollar. From what I can tell the Exo is the most powerful and best bang for your buck. Right now 8tb Firecuda is $203 and a 16gb x16 is $223. I get double the space for $20 bucks and possibly even better performance so why would anyone go for the firecuda other than the power consumption?

        I have 21 tb worth of data… On my 6 Seagate 4.5 tb drives. Can I use EXOS to just store data on it? Not in nas. Just archival purpose. Just copy and store data and then only read from it now and then. Replace it after 10 years.

      358. How valuable is “free data recovery” for a drive that lives in a fault tolerant array?
        If fewer drives fail than your fault tolerance can handle, there’s nothing to recover. Just replace the drive and rebuild.
        If more drives failed than your fault tolerance can handle, the data recovery people will need all of the drives in the array and a copy of the device they were running in for a “maybe”.

        If I have data that is important enough to protect with a fault tolerant array of disks, I back it up.

        On another note, if an enterprise is going to be banging away at a NAS, wants better speed and is concerned about life expectancy, they’re probably in the SAS drive range. A 15k rpm SAS compared to a 7.2k SATA with the 15k drive being rated for 50% more hours….

        That being said, the expansion of storage has been amazing. I remember managing a 1.5TB SAN with a Brocade switch that around 5k employees shared at a cost of over $500k in the early 2000’s The “cold storage” was retrieved by a robotic tape drive array and optical storage. Now a $100 drive can hold that. Storage engineers used to earn $150k to come up with ways to share 1.5TB of data.

      367. Currently: NAS 4-bay RAID 5, WD RED @6TB each.
        Want: 8-bay, expandable, 14-16TB each same RAID.
        I write every day and ready every day. My RAID capacity is maxed (about 1TB space left).
        I’m torn EXOS and IronWolf Pro.
        When you say, “recovery service”, are you saying a service provided, or a software package included inside of the HDD? If it’s a service, mail in, or something like that, it’s not a factor for me.
