    en.wikipedia.org/wiki/Power-on_self-test

    A power-on self-test (POST) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on. [ 1 ] POST processes may set the initial state of the device from firmware and detect if any hardware components are non-functional.

    A drive that implements S.M.A.R.T. may optionally implement a number of self-test or maintenance routines, and the results of the tests are kept in the self-test log. The self-test routines may be used to detect any unreadable sectors on the disk, so that they may be restored from back-up sources (for example, from other disks in a RAID ).

    The power MOSFET is the most common power device in the world, due to its low gate drive power, fast switching speed, [13] easy advanced paralleling capability, [13] [14] wide bandwidth, ruggedness, easy drive, simple biasing, ease of application, and ease of repair. [14]

    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.

    en.wikipedia.org/wiki/Driving_cycle

    The "Drive-cycle" basically is the representative of the road. Drive cycles are used to reduce the expense of on road tests, time of test and fatigue of the test engineer. The whole idea is to bring the road to the test lab (a chassis dynamo-meter) or to the computer simulation. Two kinds of drive cycle can be made.

  9. Hard disk drive performance characteristics - Wikipedia

    en.wikipedia.org/wiki/Hard_disk_drive...

    On SCSI hard disk drives, the SCSI controller can directly control spin up and spin down of the drives. Some Parallel ATA (PATA) and Serial ATA (SATA) hard disk drives support power-up in standby (PUIS): each drive does not spin up until the controller or system BIOS issues a specific command to do so. This allows the system to be set up to ...
