As of December 31, 2023, we had 274,622 drives under management. Of that number, there were 4,400 boot drives and 270,222 data drives. This report will focus on our data drives. We will review the hard drive failure rates for 2023, compare those rates to previous years, and present the lifetime failure statistics for all the hard drive models active in our data center as of the end of 2023. Along the way we share our observations and insights on the data presented and, as always, we look forward to you doing the same in the comments section at the end of the post.

As of the end of 2023, Backblaze was monitoring 270,222 hard drives used to store data. For our evaluation, we removed 466 drives from consideration which we’ll discuss later on. This leaves us with 269,756 hard drives covering 35 drive models to analyze for this report. The table below shows the Annualized Failure Rates (AFRs) for 2023 for this collection of drives.

One zero for the year: In 2023, only one drive model had zero failures, the 8TB Seagate (model: ST8000NM000A). In fact, that drive model has had zero failures in our environment since we started deploying it in Q3 2022. That “zero” does come with some caveats: We have only 204 drives in service and the drive has a limited number of drive days (52,876), but zero failures over 18 months is a nice start.
