Provides alerts for proactive replacement of the drive
before the endurance is depleted. Provides endurance

standard method defined by NVMe for Solid State Drive
to report NAND wear through the "Get Log" command
SMART/Health Information Percentage Used field. The
units are whole percentage of wear.
Percentage Used: Contains a vendor specific estimate of
the percentage of NVM subsystem life used based on
the actual usage and the manufacturer's prediction of
NVM life. A value of 100 indicates that the estimated
endurance of the NVM in the NVM subsystem has been
consumed, but may not indicate an NVM subsystem
failure. The value is allowed to exceed 100. Percentages
greater than 254 are represented as 255. This value is
updated once per power-on hour (when the controller is
not in a sleep state).
Refer to the JEDEC JESD218A standard for SSD device
life and endurance measurement techniques.
Energy storage components complete buffered writes to
the persistent flash storage in case of a sudden power
loss.
Supports testing of the power loss capacitor. Power is
monitored using SMART (Self-Monitoring, Analysis, and
Reporting Technology) attribute critical warning.

access includes NVMe-MI, the VPD page and
temperature sensor. On this device the VPD is supplied
as blank "FFs".
