Got a CCTV box to fill? That's its home. We list it because surveillance drives show up in any price-per-TB hunt. For a NAS array, though, you'd be running it off its rating. Five years of warranty is the other draw, and on a drive you'll leave spinning for most of a decade that's worth having.
!Watch out for
WD doesn't rate it for NAS use at all, which rules it out for an array as far as we're concerned. It's a 7,200 rpm drive and you'll hear it working.
Backblaze doesn't run enough of these for a failure rate we'd publish. On paper it makes 20 dB at idle and 36 dB seeking. WD lists 5.7 W at idle and 6.6 W working, which comes to 50 kWh a year for a drive that idles around the clock.
