This is an incomplete list of software that reads S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) data from hard drives. Name Operating system
The disk drives would measure the disk's "health parameters", and the values would be transferred to the operating system and user-space monitoring software. Each disk drive vendor was free to decide which parameters were to be included for monitoring, and what their thresholds should be. The unification was at the protocol level with the host.
For example, AFR is used to characterize the reliability of hard disk drives.. The relationship between AFR and MTBF (in hours) is: [1] = (/) This equation assumes that the device or component is powered on for the full 8766 hours of a year, and gives the estimated fraction of an original sample of devices or components that will fail in one year, or, equivalently, 1 − AFR is the fraction of ...
It is used to predict drive failure, supported from almost all Hard Drives and SSds. 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.
The command supports physical and virtual storage including hard disk drive (HDD), solid state devices , and solid state hybrid drives . [5] It provides control over the testing methods, duration, threads, queues, IO and processor affinity, and reporting. [6] In 2024, the command was updated to handle modern workloads and hardware like NVMe.
The software is designed to find, test, diagnose and repair hard disk drives, reveal problems, display health and avoid failures by using S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) function of hard disk drives. [34] [35] [36] The detected information can be saved to file in formats such as HTML, text, or XML. [37] [38] [39]
