Average Active Power Consumption
The average active power consumption 16 is defined as the blended read/write/idle
power used by the drive while in operation with a commonly used operating
system. It is measured using the MobileMark ® 2014 benchmark with DIPM (Device
Initiated Power Management) enabled. When DIPM is enabled, the drive is allowed
to enter low-power modes during host idle times. This benchmark simulates the
typical usage of user applications in a Windows environment, providing a
reproducible test for measuring average active power consumption.
The following table provides the average active power and average current values
for all WD Blue 3D NAND SATA SSD storage capacities (250GB, 500GB, 1TB and
2TB).
