Interesting but I don't understand what "222.77%" failure rate mean for ST1500DL003 in 2015 ? Each disk died twice !?

- atYevP 11y agoYev from Backblaze here -> Not necessarily, it just means that if we had a set of those drives and replaced them multiple times over a given period, that number can be quite high. We're comparing the drives that failed against the number we have spinning, not the total we've had in service.
- Rexxar 11y agoThanks for explanation. (I would have preferred a definition "failures / number of disk bought", but, in practice, the result is probably very similar for all other models)
