Who the Exos 7E10 6 TB is for

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

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.

There's no Backblaze data worth quoting here. 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. Put four in RAID 5 and you'll have 18 TB to fill (Windows will call it 16.4 TB).
