E2h
Timed Workload Media Wear
Raw value: measures the wear seen by the SSD (since
reset of the workload timer, attribute E4h), as a
percentage of the maximum rated cycles. Divide the raw
value by 1024 to derive the percentage with 3 decimal
points.
Normalized value: always 100.

E3h
Timed Workload Host Read/Write Ratio
Raw value: shows the percentage of I/O operations that
are read operations (since reset of the workload timer,
attribute E4h). Reported as integer percentage from 0 to
100.
Normalized value: always 100.

E4h
Timed Workload Timer
Raw value: measures the elapsed time (number of
minutes since starting this workload timer).
Normalized value: always 100.

E8h
Available Reserved Space
Raw value: reports number of reserve blocks remaining.
Normalized value: begins at 100 , which corresponds to
100 percent availability of the reserved space. The
threshold value for this attribute is 10 percent availability.

E9h
Media Wearout Indicator
Raw value: always 0.
Normalized value: reports the number of cycles the NAND
media has undergone. Declines linearly from 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.

EAh
Thermal Throttle Status
Raw value: reports Percent Throttle Status and Count of
events
Byte 0: Throttle status reported as integer percentage.
Bytes 1-4: Throttling event count. Number of times
thermal throttle has activated. Preserved over power cy-
cles.
Byte 5: Reserved.
Normalized value: always 100.

F1h
Total LBAs Written
Raw value:
reports the total number of sectors written by
the host system. The raw value is increased by 1 for every
65,536 sectors (32MB) written by the host.
Normalized value: always 100.
1 1 0 0 1 0 0 (none)
F2h
Total LBAs Read
Raw value: reports the total number of sectors read by the
host system. The raw value is increased by 1 for every
65,536 sectors (32MB) read by the host.
Normalized value: always 100.
