![]() Measures the wear seen by the SSD (since reset of the Timed Workload Timer, attribute E4), as a percentage of the maximum rated cycles. The raw value increases by 1 for every 65,536 sectors written by the host. The raw value reports the total number of sectors written by the host system. The total number of encountered SATA interface Cyclic Redundancy Check (CRC) errors. The normalized value is the results equation min (150-current temp, 100). The raw value is the current temperature. Temperature reading is the value direct from the internal sensor. An unsafe shutdown occurs whenever the device is powered off without STANDBY IMMEDIATE being the last command. The raw value reports the cumulative number of unsafe (unclean) shutdown events over the life of the device. Unsafe Shutdown Count (Power-off Retract Count) Case temperature is calculated based on an offset from internal temperature sensor. Byte 3 = Recent maximum case temperature (° C).Byte 2 = Recent minimum case temperature (° C).Byte 0 = Current case temperature (° C).Reports the SSD case temperature in degree Celsius. The raw value shows the count of errors that could not be recovered using Error Correction Code (ECC). The normalized value begins at 100 and decrements by 1 for each LBA tag mismatch detected. Reports number of errors encountered during Logical Block Address (LBA) tag checks within the SSD data path. Also known as “Power-off Retract Count” per magnetic-drive terminology. An “unclean shutdown” is the removal of power without STANDBY IMMEDIATE as the last command (regardless of PLI activity using capacitor power). Reports number of unclean shutdowns, cumulative over the life of the SSD. The normalized value, beginning at 100, shows the percent remaining of allowable erase fails. The raw value shows total count of erase fail. The normalized value, beginning at 100, shows the percent remaining of allowable program fails. The raw value shows total count of program fails. The threshold value for this attribute is 10 percent availability. The normalized value begins at 100 (64h), which corresponds to 100 percent availability of the reserved space. Reports the number of reserve blocks remaining. The raw value reports the cumulative number of power-cycle events (power on/off cycles) over the life of the device. If DIPM is turned off, the recorded value should match the clock time, as all three device states are counted: active, idle, and slumber.If DIPM is turned on, the recorded value does not include the time that the device is in a slumber state.Note: The On/Off status of the Device Initiated Power Management (DIPM) feature affects the number of hours reported. The raw value reports the cumulative number of power-on hours over the life of the device. The raw value shows the number of retired blocks since leaving the factory (grown defect count). Your SSD or drive may not support some of these attributes. These attributes vary depending on the Intel SSD or other drive selected. Self-Monitoring, Analysis and Reporting Technology (SMART) is an open standard used by drives and hosts to monitor drive health and to report potential problems.Įach drive operates under a predefined set of SMART attributes and corresponding threshold values, of which the drive should not pass during normal operation.ĭescriptions of some SMART Health Info attributes are shown in the following table.
