Abstract

See full text

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.
