Assignee: WESTERN DIGITAL TECHNOLOGIES, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 9:
10. A data storage system, comprising:
a system power supply configured to provide a system voltage supply level; and
a non-volatile memory drive connected to receive the system voltage supply level, the non-volatile memory drive configured to:
measure a first amount of power drawn by the non-volatile memory drive when in an idle state and at a first temperature;
measure a second amount of power drawn by the non-volatile memory drive when in the idle state and at a second temperature, where the second temperature is different than the first temperature;
perform a comparison of the first amount of power to a first nominal power value;
perform a comparison of the second amount of power to a second nominal power value;
based on the comparison of the first amount of power to the first nominal power value, determine a first static power offset value for the non-volatile memory drive;
based on the comparison of the second amount of power to the corresponding second nominal power value, determine a corresponding second static power offset value for the non-volatile memory drive;
store the first static power offset value and the second static power offset as parameter values on the non-volatile memory drive;
offset the system voltage supply level based on either the first static power offset value or the second static power offset value;
select from the first and the second static power offset values; and
operate the non-volatile memory drive using the system voltage supply level offset by the selected one of the first static power offset value or the second static power offset value.
