Is the Exos X16 10 TB right for you?

It's at home in a rack or a garage, where 7,200 rpm of spinning rust can whirr away all day without bothering anyone. You also get five years' warranty, two more than the cheapest NAS lines.

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. Seagate's manual only says ‘perpendicular recording’, which doesn't settle CMR versus SMR. That's annoying on a drive you'd put in an array.

Backblaze doesn't run enough of these for a failure rate we'd publish. Seagate's datasheet puts it at 28 dB idle and 32 dB seeking. Power draw is 5 W idle on Seagate's figures, or 44 kWh a year if it spends the whole year idling. Put four in RAID 5 and you'll have 30 TB to fill (Windows will call it 27.3 TB).
