2. I just bought a Beelink EQR6 Ryzen 5 24GB RAM, and a Crucial 4Tb SSD, for less than a turnkey NAS. It’ll run rings around a turnkey NAS and provide more than enough storage for my needs, all while being near silent. I may add a second 4Tb SSD as a parity drive. I’m probably going to use unraid so that I have that choice.

   If I had need for more than 16TB storage, I’d probably build a DIY NAS and run TrueNas Scale.

3. More is faster and more reliable using a raid array with two drive redundancy

4. I think you got most of it, what you maybe have not talked about is that if you use RAID 6 can you buy different drives at different times from different brands and over time slowly switching drive out as you see fit, you do never have to put the system offline, and you do never have to copy one large drive to a new one. In short, just feed a new HDD once in a while and the system will never go down.

15. I gather it should be internationally available deals, right?
    As I just scored a TS-h1277XU-RP, a TS-H1886XU-RP and a few TS-h1677AXU-RP-R7’s for really ridiculous very low prices but only available locally. But I would also guess the average user wouldn’t be into such models either. But the prices, I couldn’t let them collect dust any longer!

16. Hello!
    I have a question, it is that I have a nas where I have set my hard drives to copy each other. Now it starts to get full, you can change some settings where you remove one of the hard drives so that both become just one. if you know what i mean????

19. If you haven’t finished that Flashstor video, could you talk about how you’d recommend filling out the bays? Which NVMe drives would you recommend?

20. Just ordered the Terramaster D8. Within hours terramaster sent an email regarding a niche issue. If using UnRaid on Linux and trying to create a RAID pool on the NVME, the device might assign both NVME with the same serial number. Firmware link provided. So.. decent customer service.

45. Once upon a time, black friday was THE time to buy electronics and computer parts…especially motherboards. I’d say for about ten years now that hasn’t been the case. Monitors, TVs, pc parts, NAS’s have been having their all time lowest prices from around mid Spring time thru Summer. I’ve still seen some super low prices on some gaming consoles and of course the budget tier TVs usually like you say Rob, about 1-3 weeks prior to black friday. I’m guessing I have around 1,000 or so camelcamelcamel price alerts set up and I’ve only been getting 3-6 daily price alert emails, same for prime day which means the prices are higher than their recent lows. There is some exceptions to the triple camel and that is the bonus % on a prime card and some sales don’t hit camelcamelcamel quick enough to alert the email but it’s rare.

46. Robert, again great video
    Thanks you for sharing!

    I was secretly looking for a new NAS, and I can’t say goodbye to the brand QNAP my current model TS-653D. But was so disappointed because after my firmware update ‘QTS firmware 5.2. 2. 2950’ I had so much trouble and I could no longer log in with my password and not even after a reset with the Cloud Key. The problem was ultimately in the QNAP QM2-2S10G1TA 2-Slot PCIe Network Expansion Card. After this I could log in with the Cloud Key (with 1 spare hard disk) Firmware downgraded and everything is now functional again. Only from now on I can no longer use my Twonkey Server because I performed a reset and it now indicates that this OS version no longer supports it. While on my identical other NAS that I had updated, but had not reset it just works fully. Very unfortunate, I was very frustrated about this, but QNAP has been in my heart since 2007! So this love can’t just end….

51. Grabbed the F4-424 Pro a week or so ago since Amazon Canada already moved some on a Limited Time Deal. Ironwolf 4TBs are holding at $124.99 CAD, so I’ll probably grab 2 to go with my existing 1 and populate my NAS after I get it setup with the OS on my (yet to arrive) SSD. I’m irritated that certain things I’d _like_ are gated behind Amazon Prime for this Black Friday though; _huge_ turnoff for any impulse purchasing when I see that already.

70. so my solution after this video was: big and many. ????
    REPLY ON YOUTUBE

71. 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
    REPLY ON YOUTUBE

72. what if i get refurbished bigger drives
    REPLY ON YOUTUBE

73. The only proper solution is more hard drives that are bigger. I don’t want to put smaller hard drives because it just eats up space that a bigger hard drive can go into instead.

    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 =(

78. 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.

80. I have HDD’s of various sizes. 2TB 4TB, 6TB, and 16TB.
    REPLY ON YOUTUBE

81. 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.

82. I would say more drives, more chances at redundancy and rpms somewhat combine with raid so the speed increases.

85. I have 20tb of games to clone and not sure which way to go lol
    REPLY ON YOUTUBE

86. 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.
    REPLY ON YOUTUBE

87. 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.

    REPLY ON YOUTUBE

90. Great video. One tip from lil ol me. First nas I ever used I bought 4 identical drives same make, model, style type. Unintended consequence was……. Same mtf. 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
    REPLY ON YOUTUBE

91. 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.
    REPLY ON YOUTUBE

92. 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.
    REPLY ON YOUTUBE

93. Lol. More and bigger lol.
    REPLY ON YOUTUBE

94. 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

    REPLY ON YOUTUBE

98. 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

99. 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.

100. Not really a fair comparison comparing 2 large drives in raid 1 vs 3 smaller drives in raid 5. The smaller drives should be raid 10.

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!

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
     REPLY ON YOUTUBE

107. 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.

     People double extra check you’re math when you are calculating.

108. 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?
     REPLY ON YOUTUBE

109. 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.

111. 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.

112. 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….

114. 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.
     REPLY ON YOUTUBE

115. 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.

116. When I first got a NAS for mass storage I got a 4 bay NAS and filled it with 4TB drives, it was nearly full after 4 years and I upgraded the drives inside it with 4 10TB drives.
     I back up the most important data off on the NAS over the movies.
     REPLY ON YOUTUBE

117. 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.

119. Well, if you follow technology you would know that ceramic glass memory has been proven to be a much smaller, cooler and vastly larger in size capability that the current SSD and HDDs. 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.

124. The answer is simple: the best is to have lots of big drives!
     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.

126. 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.

134. 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.

148. What about both, more big harddisc X3
     REPLY ON YOUTUBE

149. 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.

151. 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.

152. 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.

154. 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

155. 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

158. 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 $$)

160. Very short version… go for more drives. More smaller drives usually work faster AND they make less noise.

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?
     REPLY ON YOUTUBE

163. 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…?

180. 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…

186. 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.

189. Noise is really a bummer for me now. I went from 4x3TB red to 3x8TB iron wolf, and the noise is more than double, and far more annoying in character. Heat and power also way higher. For next upgrade I want 14TB plus disks, and they are all horribly loud. I want high capacity, but low noise, low speed, low energy, since I can have multi TB of NVMe cache.

190. Very informative videos. You give info that is very relevant without beating around the bush. 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.

193. I think the mistake people make with NAS and especially raid5/6 is they think its a backup and its not. 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.

194. I have adopted this rule now; Any HDD capacity less than 1.5x what you can get for $200 on the SSD side, is to be considered obsolete.

     Currently you can get 4TB SSDs for just north of $200, that means 6TB (1.5 x 4) drives are now the smallest HDD that is worth getting. 6TB HDDs are now $90, while 4TB HDDs are $60. Up to each and everyone to put their cutoffs though!

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.

206. 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.

207. You REALLY don’t want to run raid 5 with just 3 drives. You risk data loss when rebuilding the array.

214. 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.

222. 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.

223. 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.
     REPLY ON YOUTUBE

224. 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.

235. 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.

Your video also completely neglected iops, focusing on sequential io and capacity.

246. 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.

256. 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.

261. 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).

269. 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.

275. I’ve mentioned this before, but if you are shopping for Pro drives, the only way to go is enterprise (Exos, Ultrastar). Depending on region they are much cheaper and also better.

276. I have an 8 bay DS1821 with 4x 8TB. The rationalisation was that as my data needs grew I could either add more 8TB or on the basis that over time costs would come down start adding say 12TBs and through SHR move to an all 12TB RAID.
     So far so good.

277. Thanks Man! I know you since the days of my first NAS, a trusty old QNAP TS-269 Pro which is really a long time ago. And you are still passionate like day one about all things NAS and beyond, how is this even possible? Always great info, always on Top. Just Wow, yeah, just WOW and thanks for all the Seaguls. I would consider a video from you without “i hate seaguls” as beeing not authentic. yeah, i love this. ????All the best for 2023 and beyond! — Bernd

279. Is Synology sponsoring your articles? Or pay you in any way?

280. Can I use RAID at a software level (TrueNAS) with sata pcie expansion cards that are not RAID capable at a hardware level?

     I’m building my very first NAS with a PC I’m retiring in a couple of months, and my motherboard does not have enough sata for the number of HDDs I want, there are a lot of sata pcie expansion cards on amazon but many of them say they are non RAID cards, so I’m not sure if I should buy them, if TrueNAS will be able to set the HDDs connected through that card in a RAID configuration.

281. Appreciate the mention that if you buy a number of the same drive from the same vendor you are likely to get drives from the same lot which if that lot has a problem means your risk for trouble is increased.

282. In general, would it be better to go with a 2 Bay NAS with two 14TB WD Red Plus drives (larger capacity but still on the quieter side), or a 4 Bay with smaller drives? This is just for home use for storage and streaming videos.

283. It would be really interesting to me if you could make videos at regular intervals for things like When will the price of hard drive come down and when will we see bigger capacities in the small classes.

284. Nice video!
     I always calculate the price per TB. 😉
     As that way there is often a HD-size (and above) that the price per TB is higher than the smaller/previous-size one. (price per TB)
     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..

285. Fantastic comparison!

286. 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 ????)

287. 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.
