More than 230,000 hard drives in operation as of December 31, 2022BackblazeHowever, there are statistical data “2022 statistical data by manufacturer and modelHe was released.

Backblaze Drive stats for 2022

The number of hard drives managed by Backblaze in 2022 was 235,608, of which 4,299 were used as boot drives and 231,309 as data drives. Of the 231,309 units used as data drives, 388 used for testing purposes and data for models with fewer than 60 units in operation were excluded. Backblaze has collected statistical data summarizing hard drive failure rates, which is open to the public.

Below is a table summarizing the failure rate of hard drives managed by Backblaze over the year from January 1, 2022 to December 31, 2022. The total number of erased hard drives was 230,921, and the overall rate was the Annual Failure Rate (AFR) ’, which is the total number of failed hard drives divided by the number of years the hard drive has been used, ‘1.37%. There are a total of 29 hard drive models powered by Backblaze, including the Seagate 8TB.ST8000NM000AThe only failure rate was 0%. However, it should be noted that only 79 units of ST8000NM000A were in operation, and the number of driving days was 22,839, which is shorter than others.

On the other hand, a 6TB Seagate hard drive.ST6000DX000It has an average usage life of 92.5 months, and it appears to be the oldest model among the hard drives Backblaze uses. The ST6000DX000 had an AFR of just 0.11% in 2021, rising to 0.68% in 2022. Backblaze praises the 2022 AFR, also a respectable number, but “it’s better considering the model has been in the works for nearly eight years.” ”

Toshiba 4 terabyte hard driveMD04ABA400VThe average length of use was 91.3 months, with an AFR of 2.04% in 2021 and an AFR of 3.13% in 2022.

The model, newly launched in 2022,HUH728080ALE604」「ST8000NM000A」「ST16000NM002J」「MG08ACA16TA」「WUH721816ALE6L45.

The table below compares the AFR for each model in 2020, 2021 and 2022.

Because the AFR is rising year over year, Backblaze compares the AFR for hard drives of 10TB or less and hard drives of 12GB or more, taking into account the possibility that drive size can affect the failure rate. However, the results show only a slight increase in AFR in both groups in 2022, and drive size does not appear to have a significant effect on the increase in AFR.

The table below summarizes the drive size, average usage period, and AFR. Excluding drives with relatively few operating days (6TB and 10TB) from the left table, the result is shown as shown in the right table. Looking at the table on the right, you can clearly see that the longer the drive is in use, the greater the AFR increase.

Here is a summary of the AFR for each engine for the period from April 20, 2013 to December 31, 2022 when Backblaze began collecting statistical data. The full-period AFR fell from 1.40% in 2021 to 1.39%.
