Is the WD Red Plus 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. CMR, thankfully. SMR and parity rebuilds don't get on.
Watch out for
If there's any chance you'll move to a bigger box later, a pro line saves buying drives twice. 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.
Backblaze doesn't run enough of these for a failure rate we'd publish. 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 Western Digital page or datasheet it came from, and "Not published" means the maker doesn't list it there.

Failure rate
Backblaze doesn't run this model, or not in big enough numbers. 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.
