NAS drives are CMR hard drives rated for 24/7 operation and vibration in multi-bay enclosures. The best value is usually found in the 8-18TB band, where price per terabyte is low and capacity is high. This table ranks NAS-rated drives on Amazon.ca by live price per terabyte, so you can fill bays at the lowest cost per terabyte. For SMR pitfalls to avoid, see our CMR vs SMR guide.

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.
