Backblaze just released its new 2023 hard drive reliability stats for 35 different models and over a quarter million drives. We started covering the company back in 2011 but have not covered the Backblaze reliability studies since 2022. The new set of 2023 data is out, so we figured we would highlight a few bits for our readers.

Here is the full set of 35 different drive models. What is remarkable is that there are still some Seagate and Toshiba models out there at 103-104 months making them over 8.5 years old.

Here is the chart with the smaller drive populations pulled out and then shown annually. What is interesting here is that the AFR has been creeping up for the last three years.

Something that Backblaze did was to pull out AFR by drive size (across vendors) over time. While many of Seagate’s other capacities seem to struggle, those 6TB Seagate drives seem to be awesome.

Under 36 months, no drive is over 1.5% AFR. After 36 months, there is not a huge amount of data for other manufacturers, but Seagate drives are the ones crossing the 1.5% threshold.
