Is the N300 12 TB right for you?

It suits a small NAS that's tucked away in a cupboard or under the stairs, where the extra pace of 7,200 rpm is welcome and the extra noise isn't your problem. It's CMR, which is what you want anywhere near a RAID or ZFS rebuild.

Watch out for

Treat that bay rating as a hard limit. Anything larger wants a pro or data-centre drive. You get three years' cover and a 180 TB a year workload rating, both on the light side if the pool's busy every day.

There's no Backblaze data worth quoting here. Put four in RAID 5 and you'll have 36 TB to fill (Windows will call it 32.7 TB).

Specifications

Each value links to the Toshiba page or datasheet it came from, and "Not published" means the maker doesn't list it there.

Failure rate

There's no Backblaze figure for this one. We only publish a rate with at least 60 drives and 50 drive-years behind it, because below that the error bars are too wide to tell you anything. The reliability page has every model that clears the bar.
