Backup specialist Backblaze, which has published hard drive failure statistics quarterly since 2013, says its second-quarter 2020 Annualized Failure Rate (AFR) is the lowest ever recorded at 0.81 per cent overall. Backblaze’s 2020 Hard Drive Reliability Statistics. In spite of everything else that happened last year, hard drives became more reliable.

Of course, this data is unfair to Seagate because its hard drive has the highest level of power and power-on time.Backblaze is a cloud service provider that uses hundreds of thousands of mechanical hard drives, and keeps detailed records on the failure rates of said drives. This week, Backblaze released its quarterly hard drive reliability stats. The HDS5C4040ALE630 (4TB) of HGST (4K) with the highest annual failure rate is 4.68%, only considering that the bad disk has only one block and the inspection time is too short, and the reference is not large.

For our evaluation we remove from consideration those drives that were used for testing purposes and those drive models for which we did not have at least 60 drives (see why below). While these statistics cannot be used to reliably judge the quality of drives from any particular manufacturer they serve as a good reference for general trends in hard drive reliability. Backblaze Q2 2020 Hard Drive Analysis Highlights Promising Boost In Overall Reliability. At the end of Q1 2020, Backblaze was using 129,959 hard drives to store customer data. If you treat them reasonably, modern drives are rock stable. The least reliable drive is also from Seagate with the 14 TB ST14000NM0138 having an AFR of 4.66 in Q4 2021 down from 6.29 in Q3 2021.

The 8TB drives I used to populate my NAS scored 0.10 better than the 0.81 average.
There are a total of 98,184 mechanical hard disks in the statistics. The reason why it is less than the total number is because the test discs with few power-on time and the models with less than 45 pieces are excluded. The annualized failure rate of all hard drives is 1.08%, which is the historical minimum.Īmong them, the highest fault is the Seagate ST4000DM000 with a capacity of 4TB, and 134 pieces are “dead”.
Look at the second quarter –Blackblaze Q2 2018 hard drive failure rates report As of June 30, BB has a total of 100,254 hard drives, including 1989 boot disks and 98,265 data disks. Storage service provider Backblaze released the hard disk service report for the second quarter of 2018.
