Mean time to data loss is similar to MTBF for disks and tapes, but is likely to differ in RAID arrays, where redundancy can protect against data loss due to component failures.

- 對于磁盤(pán)和磁帶設備來(lái)說(shuō),平均數據丟失時(shí)間的概念與MTBF相似,但是對于RAID陣列來(lái)說(shuō),平均數據丟失時(shí)間可能與MTBF不同,這是因為在RAID中,冗余性能夠保護組件故障條件下數據丟失情況的發(fā)生。
