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.
