Strong pick as a cold copy

Rated CMR (conventional magnetic recording) — the right recording type for a large cold copy. CMR keeps a full-library backup pass fast even at 16–24 TB, which is the whole point of the offline slot in a 3-2-1 plan: rotate two drives monthly, keep one powered off, and the backup tooling (Veeam, Duplicati, Hyper Backup, HBS 3) does the scheduling. Full rule and vendor tool table: 3-2-1 for NAS.

Compatibility verdict

It appears on the official compatibility lists of 16 machines and series — 16 UGREEN. Check the class badge above: drives tagged NAS or Enterprise are built for 24/7 multi-bay operation. Desktop-class drives often lack vibration resistance and are usually absent from vendor HCLs. Its series rating is on file as CMR (conventional) — what RAID rebuilds and full-library copies want.
