S.M.A.R.T., Self-Monitoring, Analysis, and Reporting Technology, typically written as simply SMART, is a monitoring system built into modern hard drives designed to detect and report a set of indicators which allows the end user to assess the stability of the drive.

SMART monitors a host of factors that are strong indicators of degrading drive performance and impending failure, including read errors, increasing spin-up time, increasing seek times, uncorrectable sectors, among dozens of other variables. Although the SMART system has been criticized for previously being non-standardized and having poor hardware implementation, the system has been fine tuned and an analysis conducted by Google using tens of thousands of retired and failed server drives indicated that the SMART system was in fact reliable and a good indicator of drive failure.
