S.M.A.R.T.
Definition
Self-Monitoring, Analysis and Reporting Technology for storage health data.
Detailed explanation
S.M.A.R.T. means Self-Monitoring, Analysis and Reporting Technology, a health-reporting system in many storage drives. Firmware records attributes such as temperature, power-on time, unsafe shutdowns, media errors, and spare capacity. Raw values and thresholds vary by maker, and a normal status cannot guarantee that a drive will not fail. NVMe health logs overlap with the concept but use protocol-specific fields rather than classic ATA attribute tables. Reallocated sectors, uncorrectable errors, wear indicators, and temperature history have different meanings across media types, so manufacturer thresholds and trends provide essential context.
