According to a recent report from Backblaze, a backup and cloud storage company, it takes an average of 2 years and 6 months for hard drives to start failing.
The company tracked all of the more than 236,000 HDDs in use and identified 17,000 devices that failed in the first half of 2023. From there he recorded the failure date, model, serial number, capacity and gross SMART value of each unit.
As Backblaze no longer uses drives below 5TB, research was unable to conclude whether higher-capacity drives tend to fail and fail sooner than those with less storage, as noted in a report by Secure Data Recovery.
Reliability of HDDs
Bakblaze also analyzed the reliability index of its hard drives through analysis of current failure rates (AFRs) in each active unit in the equipment fleet.
HDDs had an average AFR of 1.4%, but hard drive manufacturers experienced failures at different times. The Seagate ST12000NM0007 12TB model received the lowest score. There were 2,023 faults in the unit and the first faults appeared after an average of 1 year and 6 months. Western Digital’s 16TB HDD was the most reliable hard drive.
