Pick it for raw capacity in a box that lives out of earshot, because 7,200 rpm enterprise drives are built to run flat out all day, every day. 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
Being 7,200 rpm, it's in the noisier, warmer class of drive, and you'll want it somewhere you don't sit.
No Backblaze failure rate for this one. They don't run enough of them, if any, for a figure worth quoting. WD's datasheet puts it at 25 dB idle and 32 dB seeking. Power draw is 5.6 W idle and 8.4 W working on WD's figures, or 49 kWh a year if it spends the whole year idling. A 4-bay box full of these gives 72 TB after one drive's worth of parity.
