Backblaze analyzes the failure rate of your hard drives
The failure rates of all larger drives (8, 10, and 12TB) are very good, 1.2% AFR (Annualized Failure Rate) or less. Many of these drives were implemented last year, so there is some volatility in the data, but it is certainly a good benchmark on the reliability of hard drives of this size.
The overall failure rate was 1.84%, this is the lowest that Backblaze has ever reached, surpassing the previous low of 2% at the end of 2017.
In the table we can see all the hard disk models implemented in the data center, where a very low failure rate is seen for Seagate's 12 TB (0.90%) model, plus some that have had a failed disk rate. 0%, like the 10 TB Seagate or the 6 TB Western Digital. The worst performer is Seagate's 4TB model, with a 2.30% failure rate.
What Backblaze reveals, is that hard drives are becoming more reliable over time, in addition to improving storage capacities more and more. It is a pity that the same evolution is not seen in the speed of reading and writing data.
