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 99 machines and series — 99 QNAP.
