Intel X25-M 4.0Mechanical Information, 4.11.8” 5 mm Intel X18-MSATA SSD, 3.5.3Power On/Off Cycles

Intel® X18-M/X25-M SATA SSD

3.5.2Mean Time Between Failure

The Mean Time Between Failure (MTBF) is calculated based on a Part Stress Analysis. It assumes nominal voltage, with all other parameters within specified range.

3.5.3Power On/Off Cycles

Defined as power being removed from the drive, and then restored. Most host systems remove power from the drive when entering suspend and hibernate as well as on a system shutdown.

3.5.4Minimum Useful Life

A typical client usage of 20 GB writes per day is assumed. Should the host system attempt to exceed 20 GB writes per day by a large margin for an extended period, the drive will enable the endurance management feature to adjust write performance. By efficiently managing performance, this feature enables the device to have, at a minimum, a five year useful life. Under normal operation conditions, the drive will not invoke this feature.
