I used to think these were interesting and used them to inform my next HDD purchase. I realized I only used them to pick a recently reliable brand, we're down to three, and the stats are mostly old models, so the main use is if you're buying a used drive from the same batch that Backblaze happens to have also used.
Buy two from different vendors and RAID or do regular off-site backups.
Mirrored raid is good. Other raid levels are of dubious value nowadays.
Ideally you use "software raid" or file system with the capabilities do scrubbing and repair to detect bitrot. Or have some sort of hardware solution that can do the same and notify the OS of the error correction.
And, as always, Raid-type solutions mostly exist to improve availability.
Backups are something else entirely. Nothing beats having lots of copies in different places.
