Should you buy the Exos 7E10 8 TB?

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. CMR, thankfully. SMR and parity rebuilds don't get on.

Watch out for

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 28 dB at idle and 32 dB seeking. Seagate lists 7.06 W at idle and 11.03 W working, which comes to 62 kWh a year for a drive that idles around the clock. Four of them in SHR or RAID 5 give 24 TB usable, or 21.8 TB once Windows has done its binary maths on it.
