Claim 18:
19. A data storage system, comprising:
means for providing a system voltage supply level; and
a plurality of non-volatile memory drives connected to receive the system voltage supply level, each of the non-volatile memory drives comprising:
means for measuring first and second amounts of power drawn by a non-volatile memory drive when in an idle state and respectively at a first temperature and a second temperature, where the second temperature is different than the first temperature;
means for performing a comparison of the first amount of power to a first nominal power value and a comparison of the second amount of power to a second nominal power value;
means for determining, based on the comparison of the first amount of power to the first nominal power value, a first static power offset value for the non-volatile memory drive and, based on the comparison of the second amount of power to the second nominal power value, a second static power offset value for the non-volatile memory drive;
means for storing the first and the second static power offset values as parameter values on the non-volatile memory drive; and
means for configuring the non-volatile memory drive to offset the system voltage supply level based on either the first static power offset value or the second static power offset value; and
means for operating the non-volatile memory drive using the system voltage supply level offset by a selected one of either of the first static power offset value or the second static power offset value.
