What HDD is best for NAS?

What HDD is best for NAS?

 

Yes, this is a popular question. Especially when your NAS has a different number of bays or even bays size.

The basic rules for NAS-compatible drives is as follows.

1-Bay and 2-Bay NAS             = You can use any drives you want. This can also include Barracuda desktop drives. Simply because data is mirrored. For power efficiency, WD Red and Ironwolf is recommended.

3-Bays and up to 8-Bay NAS  =  When you choose RAID5/6/SHR it is recommended to go for any NAS drives such as WD Red, Red Pro, Ultrastar, Gold, EXOS, Ironwolf, and Ironwolf Pro.

8 Bays and more                     =Red Pro, Ultrastar, Gold, EXOS,  Ironwolf Pro.

 

Should I get bigger os smaller drives?  Bigger 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 table below?

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.

TOTAL CAPACITY NEEDED IN TB? HDD bays available? Redundancy? Budget? NAS HDD ONLY?
