Intel® Solid-State Drive Toolbox User Guide Unsafe Shutdown Count (Power-off Retract Count) C0 The raw value reports the cumulative number of unsafe (unclean) shutdown events over the life of the device. An unsafe shutdown occurs whenever the device is powered off without STANDBY IMMEDIATE being the last command. Temperature - Device Internal C2 Reports internal temperature of the SSD. Temperature reading is the value direct from the internal sensor. The raw value is the current temperature. The normalized value is the results equation min(150-current temp, 100). CRC Error Count C7 The total number of encountered SATA interface Cyclic Redundancy Check (CRC) errors. Host Writes E1 The raw value reports the total number of sectors written by the host system. The raw value increases by 1 for every 65,536 sectors written by the host. Timed Workload, Media Wear E2 Measures the wear seen by the SSD (since reset of the Timed Workload Timer, attribute E4), as a percentage of the maximum rated cycles. Timed Workload, Host Read/Write Ratio E3 The percentage of I/O operations that are read operations (since reset of the Timed Workload Timer, attribute E4). Timed Workload Timer E4 Measures the elapsed time (number of minutes) since starting this workload timer. Available Reserved Space E8 Reports the number of reserve blocks remaining. The normalized value begins at 100 (64h), which corresponds to 100 percent availability of the reserved space. The threshold value for this attribute is 10 percent availability. Media Wearout Indicator Reports the number of cycles the NAND media has undergone. The normalized value declines linearly from E9 100 to 1 as the average erase cycle count increases from 0 to the maximum rated cycles. Once the normalized value reaches 1, the number will not decrease, although it is likely that significant additional wear can be put on the device. Total LBAs Written F1 Counts sectors written by the host. Total LBAs Read F2 Counts sectors read by the host.
