Abstract
To provide more uniform performance levels for solid state drive (SSDs), the static power level used by an SSD in an idle state is measured and used to determine a static power offset for each of the drives. The static power offset is set as a parameter for the SSD and used to offset a received power supply level for use on the drive. For a data storage system of multiple SSDs, a common scaling factor can be used to set the degree to which the static power offset is implemented, allowing for a choice between uniformity of power and uniformity of performance for the SSDs of a data storage system.
