5.4.1.1 Timed Workload Endurance Indicators
Timed Workload Media Wear Indicator ID E2h
This attribute tracks the drive wear seen by the device during the last wear timer loop, as a
percentage of the maximum rated cycles. The raw value tracks the percentage up to 3 decimal
points. This value should be divided by 1024 to get the percentage.
For example: if the raw value is 4450, the percentage is 4450/1024 = 4.345%. The raw value is held
at FFFFh until the wear timer (attribute E4h) reaches 60 (minutes) after a SMART EXECUTE OFFLINE
IMMEDIATE (B0h/D4h) subcommand 40h to the SSD. The normalized value is always set to 100 and
should be ignored.
Timed Workload Host Reads Percentage ID E3h
This attribute shows the percentage of I/O operations that are read operations during the last
workload timer loop. The raw value tracks this percentage and is held at FFFFh until the workload
timer (attribute E4h) reaches 60 (minutes). The normalized value is always set to 100 and should be
ignored.
Workload Timer ID E4h
This attribute is used to measure the time elapsed during the current workload. The attribute is
reset when a SMART EXECUTE OFFLINE IMMEDIATE (D4h) subcommand 40h is issued to the drive.
The raw value tracks the time in minutes and has a maximum value of 2
^32
= 4,294,967,296 minutes
(8,171 years). The normalized value is always set to 100 and should be ignored.
