Secure Data Recovery, a data recovery company, has determined that failed hard drives fail after an average of 25,233 hours of use — that's 1,051 days, or two years and ten months.

The average hard drive life expectancy before failure was derived from data from 2007 failed incidents, from which data was restored by the company's specialists. Timothy Burlee, the author of the material, calculated the number of hours from the moment the disk was first turned on until it arrived at the workshop, and also took into account the number of bad sectors for failed devices. Drives that fail due to extreme circumstances such as power surges, malware, natural disasters, or accidental damage were excluded from the study.
On average, there were 1548 bad sectors per device, according to the figures. For comparison, Toshiba drives showed themselves to be the worst of all with a result of 18,632 hours.
Curiously, the five most fault-tolerant hard drives were manufactured before 2015, while the most less durable ones were released after that date. Head designs have become more complicated, and complexity has traditionally increased the likelihood of failure.
Backblaze, a company that provides cloud storage services, does not provide data on the average life of a hard drive in general.
