Good for

  • Busy arrays (550 TB a year)

Should you buy the MG09 14 TB?

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. 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

At 7,200 rpm it's from the louder, warmer class. Fine in a cupboard, less fun on a desk.

Backblaze doesn't run enough of these for a failure rate we'd publish. Power draw is 3.77 W idle and 7.96 W working on Toshiba's figures, or 33 kWh a year if it spends the whole year idling. A 4-bay box full of these gives 42 TB after one drive's worth of parity.
