CMR VS SMR 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 You can go brand specific such as Seagate, WD, and Toshiba. WD might offer things like OptiNAND
Home vs Business 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 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.

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. 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?
How do I find the actual hard drive size?
The hard drive capacity calculation method of Manufacturer is: 120GB=120,000MB=120,000,000KB=120,000,000,000 bytes; while the hard drive capacity calculation method of is: 120,000,000,000 bytes/1024=117,187,500KB/1024=114, 440.9MB/1024=111.8GB.

What’s the 3 Best HDD for a DAS enclosure with RAID
WD Red plus, Ironwolf for up to 8 bays. Red Pro, Gold, Ironwolf Pro, Exos for 8 + bays.
Can somebody please help me.
I have a QNAP NAS with 4 x 10TB SG IronWolf + a 500GB M.2 (cache) in a raid 6.
Sometimes drive performance seems to be quite slow (< 30MBytes per sec) If I add 1 or 2 HDDs (nas max is 6 HDDs + 2 M.2s) will it improve, reduce or not effect performance? Thanks <3

If you really wanted the best price of course you would buy used. But I get that there is no affiliate income in that suggestion. So I’ll just say it here.

I picked up 4x WD UltraStar DC HC550 16TB for my raid at just under $14/TB. I think I did pretty good.

I think your videos and reviews are excellent, and the hard drive pricing comparison tool looks very useful (thank you), BUT, I was staggered when I visited the nascompares website and opened the Vendor Preferences section of the cookies permissions…more than 1500 (yes, one thousand five hundred !!!) “Legitimate Interest” and other cookie permissions which seemingly can only be turned off (or activated, if that’s what the website visitor wants to do) MANUALLY. Yes, it took a looong time. Please, just provide a simple and all-encompassing “Reject All” option in cookie preferences. Cookies should be (IMO) opt-in. not ‘gotcha’.

Wow that’s super useful! I wish it also did Europe but I get that’s probably pretty tricky to do.

Do you have a video on different ways to migrate to a new NAS with same/different bays. Maybe you could add to the tool a migration option that can calculate the least number of drives / steps required e.g. go from raid 5 to raid 1 larger drives and then reuse the raid 5 drives once migrated. Hopefully this makes sense. What do people do with old working drives?

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.

Price per TB crossed tabbed with with Mtbf [actual], size and noise, are the items I try to balance.

What’s better for the NAS HDD’s health: keep the NAS running all the time, or turn it on only when needed?
I use it maybe 3 times per week, for about 4 hours each time.

Didn’t quite think things through enough when I ordered drives for my first NAS. Had to decide between Synology IronWolf, and WD Red (not Pro or Plus). Ended up going with the standard Red based on some reviews that weren’t quite… complete. So now I have a drive that isn’t officially supported and for a reason I still don’t quite understand is just worse in the long run than the IronWolf. All of this because I wanted to save 15€

I went with Raid5 – 4 x 18tb drives for my 4 bay for best price, reliability, space balance for me. Seagate x18 drives at $15 per TB.

No offense to the work you’ve put in on this tool, but none of your calculators have ever worked for me. Disabling ad blocker and different browsers, just doesn’t work. Not sure what I’m doing wrong. ????????♂

Thank you guys!!! Anestis from Greece here, just got my first NAS, a Qnap 464, thanks to your recommendations for 4bay Nas and now trying to decide what kind of hard drives to buy. I need a lot of space (50tb to 60tb) usable space in RAID5 and the cost is very high. Do you think that Ultrastar series is suitable for my case? I’m going to use my NAS for multimedia library and PC backup mainly. THANKS AGAIN for your great articles and useful videos!!!
REPLY ON YOUTUBE
It would be great if you did the same for shucked drives. Many Synology users use them. Frankly, I have one server with (7) 14TB drives and another with (6) and not a peep about them for over two years so far. Still healthy. ????
REPLY ON YOUTUBE
One thing I would add, is an actual $/TB column, as it helps to work out Amazon’s sales versus other retailers during various promotional periods.

I think reliability and loudness would be the big secondary factors. My nas is my office where I work from home, those exos drives probably too loud?

Ty for this. I have a ext4 shr2 raid in synology, and am considering getting a newer model and using that to switch from ext4 to btrfs… I wish there was an easy way to switch between ext4 and btrfs without new drives… but I may just expand my drive sizes at the same time as transitioning from ext4.
