S.M.A.R.T., where it is one of the attributes.attributes like POH played a heavy role in device failures.
POWER ON TIME SERIAL
Google tested over 100,000 consumer grade serial and parallel ATA hard disks, finding evidence that S.M.A.R.T. Once a drive has surpassed the 43,800 hour mark, it may no longer be classed as in "perfect condition".
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. It is used to predict drive failure, supported by manufacturers such as Samsung, Seagate, Toshiba, IBM ( Hitachi), Fujitsu, Maxtor, Kingston and Western Digital. attributes (originally known as IntelliSafe, before its introduction to the public domain on, by the computer hardware and software company Compaq), while the sun is shining and solar power is contributing to the power grid. Power-on hours ( POH) is the length of time, usually in hours, that electrical power is applied to a device.Ī part of the S.M.A.R.T. Learn about Time-of-Use residential rate plans and why you should switch. A 2.4 second power on time makes it easier to catch the action in time and, with an included docking cradle, users will find it simple to not only charge the HMX20C, but also to utilize the HDMI input and component connectivity to easily view and share home movies directly on an HDTV or via USB connection to PC. The Automatic Power Up field must be enabled to use this feature. The raw value of this attribute is constantly increasing when the hard disk is under power (running, but not neccessarily performing a read or write operation). This value is supported by most modern IDE and S-ATA hard disks. The length of time that electrical power is applied to a device Time (hh:mm:ss) of Alarm: This field sets the time for automatic power-up, based on a military/24-hour clock. Hard disk power on time can be determined by examining the 9 'Power on time count' S.M.A.R.T.
