“Backblaze Drive Stats for 2022”
https://www.backblaze.com/blog/backblaze-drive-stats-for-2022/

“The latest figures published on the Backblaze blog cover the hard drive failure rates it saw for 2022 across its storage portfolio, which stood
at 235,608 individual drives as of December 31. However, 4,299 of these
were boot drives while another 388 drives were removed from
consideration because they had been used for testing purposes or were
models for which the company did not have at least 60 drives in
operation. This still leaves statistics covering 230,921 hard drives
used for data storage purposes.”

“According to Backblaze’s principal cloud storage evangelist, Andy
Klein, there was a notable increase in the annualized failure rate (AFR) during last year, rising from 1.01 percent in 2021 to 1.37 percent
during 2022. “In our Q2 2022 and Q3 2022 quarterly Drive Stats reports,
we noted an increase in the overall AFR from the previous quarter and attributed it to the aging fleet of drives, but is that really the
case?” he asked.””

I wonder if they are also seeing a higher failure from the helium filled
hard drives ? And, the data is fairly clear, if you need or want
reliability, buy WD drives.

More comments on the data:

I am totally fascinated by the concept of 235,608 individual drives.
That is a lot of building and maintaining disk farms.
