3-2-1 cold backup fit

No series-level recording rating is on file for this part number yet — check the exact model for CMR vs SMR before buying it as a large cold copy (SMR is the one trait that makes a 16 TB+ backup copy painfully slow). The 3-2-1 guide and the backup tools encyclopedia cover what to schedule it with.

Compatibility verdict

It appears on the official compatibility lists of 94 machines and series — 94 QNAP. This is a Enterprise-class drive: rated for heavier sustained workloads than desktop drives. It is a strong pick for a NAS running 24/7, large-array rebuilds or camera workloads, and enterprise lines are also the drives most widely listed across all five vendors' HCLs. No series-level recording rating is on file for this part number yet, so check CMR vs SMR on the exact model before buying for an array.
