It is used to predict drive failure, supported from almost all Hard Drives and SSds. Power-on hours is intended to indicate a remaining lifetime prediction for hard drives and solid state drives , generally, "the total expected life-time of a hard disk is 5 years" [ 3 ] or 43,800 hours of constant use.
Wear leveling (also written as wear levelling) is a technique [1] for prolonging the service life of some kinds of erasable computer storage media, such as flash memory, which is used in solid-state drives (SSDs) and USB flash drives, and phase-change memory.
