- Backblaze has been tracking hard drive failure rates (AFRs) since 2013.
- Recent data shows HDDs are lasting longer with fewer errors.
- AFR peaks dropped from 13.73% (2013) and 14.24% (2021) to 4.25% (2023).
- Failure rates now peak at 10 years and 3 months, a significant improvement.
- Drives analyzed were from HGST, Seagate, Toshiba, and WDC, ranging from 4TB to 24TB.
- Average drive age in the study was 3.7 months to 103.9 months (~8.7 years).
- Backblaze compares HDD failure rates to the 'bathtub curve' engineering principle.
