Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) is a diagnostic system built into hard disk drives and solid-state drives. It continuously tracks hardware indicators such as read error rates, temperature, and reallocated sector counts. System administrators monitor these metrics to replace degrading storage media before a catastrophic failure causes data loss.
