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. Recording is CMR, the right kind for RAID and ZFS.
!Watch out for
You get three years' cover and a 180 TB a year workload rating, both on the light side if the pool's busy every day.
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 4.14 W at idle and 7.48 W working, which comes to 36 kWh a year for a drive that idles around the clock. Four of them in SHR or RAID 5 give 48 TB usable, or 43.7 TB once Windows has done its binary maths on it.
