Go for it if you're building something bigger than a 4-bay box. It also earns its keep on a busy pool where scrubs and rebuilds never let up, because the 550 TB a year workload rating is there for exactly that. You also get five years' warranty, two more than the cheapest NAS lines. Recording is CMR, the right kind for RAID and ZFS.
!Watch out for
Being 7,200 rpm, it's in the noisier, warmer class of drive, and you'll want it somewhere you don't sit.
Backblaze doesn't run enough of these for a failure rate we'd publish. Synology lists 4.16 W at idle and 8.35 W working, which comes to 36 kWh a year for a drive that idles around the clock. A 4-bay box full of these gives 48 TB after one drive's worth of parity.
