Is the BarraCuda 16 TB right for you?

As a second drive in a PC, or a backup you plug in once a week, it does what you need.

Watch out for

No NAS rating from Seagate. For an array, pick a NAS line instead. 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. Seagate's datasheet puts it at 28 dB idle and 32 dB seeking. Power draw is 6.7 W idle and 8.9 W working on Seagate's figures, or 59 kWh a year if it spends the whole year idling.
