Frequently asked questions

What is the best value NAS drive?

Usually an 8-18TB CMR NAS drive, where price per terabyte is lowest. The table ranks NAS drives by $/TB on Amazon.ca.

Do NAS drives need to be CMR?

Strongly preferred. SMR drives can stall during RAID rebuilds and heavy writes. NAS-rated lines are CMR; see our CMR vs SMR guide.

Can I use renewed enterprise drives in a NAS?

Yes, many home-lab builders do for the low price per terabyte. Keep redundancy and check drive health on arrival.
