Recently, the cloud storage and backup company Backblaze Its new annual report on the failure rate of hard drives in 2022 has published Today, many consumers are using existing SSDs instead of HDDs, however, older hard drives are still used as high-capacity secondary storage, and the company’s statistics provide the latest ranking of these components in terms of their failure rates. has specified
According to Backblaze, as of December 2022, the company used nearly 235,608 hard drives, of which 4,299 were boot drives and the remaining 231,309 were used as storage drives. The recently published results focused on 231,000 storage drives. In this regard, the Seagate Exos 8TB drive has been declared as one of the best HDDs in this list without the slightest failure.
However, Backblaze has admitted that only 79 hard drives of this model are actively working, and the success rate is relatively low. In addition, this Seagate 8 TB hard drive model has been used as a reserve drive for problematic hard drives. The annual failure rate (AFR) for hard drives has increased over the past three years, and for example, it is reported to be close to 0.93% in 2020 and close to 1.10% in 2021.
The annual failure rate for 2022 is also recorded at 1.37%. The reason for the high failure rate is the aging of these parts. Further, it can be said that HGST Ultrastar He8 8TB and Seagate Exos X14 14TB hard drives had the highest failure rates with 5.27 and 5.70%, respectively. However, the number of days of operation of these hard drives and their total number in these tests are also less than other hard drives.
Data published by Backblaze for 2022 confirms the relationship between drive age and hard drive failure rates, and for example, 4 TB drives with an average lifespan of 81.1 months experienced a failure rate of 1.70. Meanwhile, 8TB drives with 67 months of use have shown a total failure rate of 1.36%.
Looking at these statistics, it can be seen that Seagate and Toshiba are the first and second in failure rate, but this does not necessarily mean Seagate’s bad performance, and the reason for that is the old HDDs of this company.
