Ranked by measured failure rate (Backblaze AFR). $/TB uses the cheapest live price where available.

Every drive here is a CMR (RAID-safe) 6TB model in current production. For a NAS or RAID array, pick the lowest failure rate you can afford; enterprise drives (Exos, Ultrastar, MG) trade some noise and power draw for the longest workload ratings. See how to choose a NAS drive for the full rundown.

Frequently asked questions

What is the most reliable 6TB NAS drive?
None of the 6TB drives have large-scale Backblaze failure data yet; choose by manufacturer class and warranty.
Are 6TB NAS drives CMR or SMR?
Every 6TB drive we recommend for NAS use is CMR (conventional recording), the RAID-safe choice. We exclude SMR drives from NAS picks.
