What makes a drive a NAS drive
A NAS drive is built to spin continuously in a box with several other drives. In practice that means three things: conventional recording (CMR) so rebuilds do not crawl, a workload rating high enough for constant use, usually 180TB a year or more, and firmware that gives up on a bad sector quickly instead of retrying for so long that the array drops the drive. Vibration tolerance matters too, because neighbouring drives shake each other. Makers state a bay limit as well, up to 24 bays among the drives here.
Choosing between them
54 of the 55 drives here are confirmed CMR. The cheapest space right now is the Seagate IronWolf 12TB at $35.75/TB. Buy the same model for every bay where you can, size for the array you want in two years rather than today, and remember that a NAS is not a backup: RAID protects against a drive dying, not against deleting the wrong folder.
MTBF figures come from the maker and are a design estimate, which is why they count for little in the score.
