Backblaze Inc. released its Q3 2025 Drive Stats report, analyzing the performance and reliability of 328,348 hard drives across its global data centers. The report noted an increase in the quarterly failure rate to 1.55%, up from 1.36% in Q2, aligning with the 2024 annualized failure rate (AFR) of 1.57%. The lifetime AFR remained steady at 1.31%. High-capacity drives (20TB and above) grew by nearly 8,000 units and now represent 21% of the active drive pool. Four drive models recorded zero failures during the quarter, including the Seagate HMS5C4040BLE640 (4TB), Seagate ST8000NM000A (8TB), Toshiba MG09ACA16TE (16TB), and Toshiba MG11ACA24TE (24TB). The report also highlighted an outlier, the Toshiba MG08ACA16TEY (16TB), which showed a 16.95% AFR due to temporary removals related to ongoing upgrades, not mechanical issues, with expectations for normalization in future reports.
