04
Start/Stop Count
For Intel SSDs, reports a fixed value of zero (0).
This type of event is not an issue for SSDs. However, hard disk drives can experience only a finite number
of these events, and therefore, must be tracked.
05
Re-allocated Sector Count
The raw value shows the number of retired blocks since leaving the factory (grown defect count).
09
Power-On Hours Count
The raw value reports the cumulative number of power-on hours over the life of the device.
Note: The On/Off status of the Device Initiated Power Management (DIPM) feature affects the number of
hours reported.
• If DIPM is turned on, the recorded value does not include the time that the device is in a slumber
state.
• If DIPM is turned off, the recorded value should match the clock time, as all three device states
are counted: active, idle, and slumber.
0C
Power Cycle Count
The raw value reports the cumulative number of power-cycle events (power on/off cycles) over the life of
the device.
AA
Available Reserved Space
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.
AB
Program Fail Count
The raw value shows total count of program fails. The normalized value, beginning at 100, shows the
percent remaining of allowable program fails.
AC
Erase Fail Count
The raw value shows total count of erase fail. The normalized value, beginning at 100, shows the percent
remaining of allowable erase fails.
B7
SATA Downshift Count
The count of the number of times SATA interface selected lower signaling rate due to error.
B8
End-to-End Error Detection Count
Reports number of errors encountered during Logical Block Address (LBA) tag checks within the SSD data
path. The normalized value begins at 100 and decrements by 1 for each LBA tag mismatch detected. The
threshold value is 90.
BB
Uncorrectable Error Count
The raw value shows the count of errors that could not be recovered using Error Correction Code (ECC).
BE
Temperature - Airflow (Case)
Reports the SSD case temperature in degree Celsius. The raw value is as follows:
Byte 0 = Current case temperature (°C)
Byte 2 = Recent minimum case temperature (°C)
Byte 3 = Recent maximum case temperature (°C)
The normalized value is 100. Case temperature is calculated based on an offset from internal temperature
sensor.
