Should you buy the WD Red Pro 16 TB?
This is the one to look at once you're past eight bays or the array's busy all day, because WD rates it for 550 TB a year and doesn't care how big the box is. 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
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, as they don't run it in big enough numbers. Four of them in SHR or RAID 5 give 48 TB usable, or 43.7 TB once Windows has done its binary maths on it.

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
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.
