The data includes basic drive information, SMART stats.
For our evaluation, we remove from consideration 231 drives which were used for testing purposes and those drive models for which we did not have at least 60 drives. 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. The Hard Drive Reliability Data Set is a collection of hard drive data from the Backblaze data center. 2020 Hard Drive Failure Rates At the end of 2020, Backblaze was monitoring 162,530 hard drives used to store data. In honor of May 4th, cloud backup company Backblaze. Of course, this model has the longest service time the second fault is Seagate’ model ST12000NM0007, capacity 12TB, which is the service time too long. By Josh Norem If you thought hard drive reliability and a galaxy far, far away could never be combined, you have much to learn. 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. Tue // 16:00 UTC Cloud storage and backup provider Backblaze has released a comprehensive report detailing reliability statistics for the hard drives it operated during the whole of 2021, with an interesting finding on its older kit.
Storage service provider Backblaze released the hard disk service report for the second quarter of 2018.
