As of December 31, 2023 , Backblaze had 274,622 hard drives under management.

In 2023 only one drive model had zero failures, the 8 TB Seagate (model: ST8000NM000A) The table below shows the Annualized Failure Rates (AFRs) for 2023 .
Each quarter we use 50,000 drive days as the minimum number to qualify as statistically relevant.
The 2023 AFR was up: The AFR for all drives models listed was 1.70% in 2023 .
This compares to 1.37% in 2022 and 1.01% in 2021 .
Throughout 2023 we have seen the AFR rise as the average age of the drive fleet has increased.
In the charts below, we group the drive models by manufacturer, and then plot the drive model AFR versus average age in months of each drive model.
HGST: The chart on the left below shows the AFR trendline ( second order polynomial) for all of our HGST models.
It does not appear that drive failure consistently increases with age.
