S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) is an industry standard for disk monitoring and testing. Disks are monitored for problems using several different kinds of self-tests. TrueNAS can adjust when and how alerts for S.M.A.R.T. are issued. When S.M.A.R.T. monitoring reports an issue, we recommend you replace that disk. Most modern ATA, IDE, and SCSI-3 hard drives support S.M.A.R.T. Refer to your respective drive documentation for confirmation.
S.M.A.R.T. tests run on a disk.
