In most storage devices, the average time it takes for a device to start working normally until a component fails (causing permanent loss of user data). For disk and tape devices, the concept of average data loss time is similar to MTBF, but for RAID arrays, the average data loss time may be different from MTBF, because in RAID, redundancy can protect against component failure conditions. Data loss occurs.
