Backblaze monitored 283,851 hard drives and SSDs at the end of Q1 2024, with a focus on AFRs and average age of drive failure. Notably, AFR decreased to 1.41%. Three drive models had no failures in Q1 2024, including a 16TB Seagate. The 6TB Seagate drives, purchased in 2015, showed zero failures, defying their age. 4TB Toshiba drives reached the end of their life, transitioning to 16TB Toshiba drives. The report analyzed drive stats data, grouping drives by size and model. Unexpectedly, the retirement drive models’ average age of failure remained at 2 years and 7 months. Lifetime AFR and manufacturers’ AFRs were also examined, with some manufacturers contributing to the general downward trend. The Drive Stats dataset is available for free download on Backblaze’s website.
