It makes most sense when you're chasing terabytes per pound and the NAS sits somewhere noise doesn't matter. Think garage, or a rack in the cupboard under the stairs. 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. It's CMR, which is what you want anywhere near a RAID or ZFS rebuild.
!Watch out for
It's a 7,200 rpm drive and you'll hear it working.
No Backblaze failure rate for this one. They don't run enough of them, if any, for a figure worth quoting. Toshiba's datasheet puts it at 20 dB idle and 32 dB seeking. Power draw is 4.35 W idle and 8.11 W working on Toshiba's figures, or 38 kWh a year if it spends the whole year idling. Put four in RAID 5 and you'll have 60 TB to fill (Windows will call it 54.6 TB).
