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. [4] [5] Typically, after a disk reaches 5 years of power-on time, the disk is more likely to fail.
This Intel 120GB SSD also appears to be in perfect condition. [ 2 ] Self-Monitoring, Analysis, and Reporting Technology ( S.M.A.R.T. or SMART ) is a monitoring system included in computer hard disk drives (HDDs) and solid-state drives (SSDs). [ 3 ]
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.
The host interface of an SSD refers to the physical connector and the signaling methods used to communicate between the SSD and the host system. This interface is managed by the SSD's controller and is often similar to those found in traditional hard disk drives (HDDs). Common interfaces include:
Many "lifetime supply" winners share that the promise is sometimes too good to be true. Find out what actually happens when a company promises a lifetime supply of something. Many "lifetime supply ...
This value should only be understood conditionally as the “mean lifetime” (an average value), and not as a quantitative identity between working and failed units. [1] Since MTBF can be expressed as “average life (expectancy)”, many engineers assume that 50% of items will have failed by time t = MTBF. This inaccuracy can lead to bad ...

The first HDD [11] had an average seek time of about 600 ms. [12] and by the middle 1970s, HDDs were available with seek times of about 25 ms. [13]Some early PC drives used a stepper motor to move the heads, and as a result had seek times as slow as 80–120 ms, but this was quickly improved by voice coil type actuation in the 1980s, reducing seek times to around 20 ms.
