at a large enough scale, almost everything backblaze uses is sufficiently reliable as measured by percentage of any pool of 100 drives that fails in a year, as they have a large amount of parity / data duplication across multiple pods, hot spares, etc.

I haven't seen any drives that really stood out as terrible in their reports in the last couple of years for 12TB+ spinning disks, although the HGST product do seem to be the most reliable.
