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 167 machines and series — 167 QNAP. This is a NAS-class drive: built for 24/7 operation with vibration compensation for multi-bay enclosures — the right tier for most 1-8 bay home or small-office NAS units. 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.
