- Look for the “Accumulated power on minutes”.
How many hours before a hard drive fails?
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” or 43,800 hours of constant use. Once a drive has surpassed the 43,800 hour mark, it may no longer be classed as in “perfect condition”.
