It suits a small NAS that's tucked away in a cupboard or under the stairs, where the extra pace of 7,200 rpm is welcome and the extra noise isn't your problem. It's CMR, which is what you want anywhere near a RAID or ZFS rebuild.
!Watch out for
Warranty's three years and the workload rating is 180 TB a year. At 12 TB that's 15 full passes of the drive a year, and a monthly scrub uses twelve of them before you've written anything.
No Backblaze failure rate for this one. They don't run enough of them, if any, for a figure worth quoting. On paper it makes 20 dB at idle and 32 dB seeking. Synology lists 3.3 W at idle and 6.85 W working, which comes to 29 kWh a year for a drive that idles around the clock. Put four in RAID 5 and you'll have 36 TB to fill (Windows will call it 32.7 TB).
