The drive receives DC power (+5V) through a native SATA power connector.

under nominal conditions, at 25°C ambient temperature. These power measurements are done with Interface Power Management modes 
like HIPM and DIPM enabled.

Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed.

During seek mode, the read/write actuator arm moves toward a specific position on the disk surface and does not execute a read or write 
operation. Servo electronics are active. Seek mode power is measured based on three random seek operations every 100ms. This mode 
is not typical.

• Read/write power and current

Read/write power is measured with the heads on track, based on three 63 sector read or write operations every 100ms.

Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads in a random track location.

• Standby mode

During Standby mode, the drive accepts commands, but the drive is not spinning, and the servo and read/write electronics are in power-
down model

*During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and power to operational levels.

**Standby power is measured at steady state (after 200ms from transition)
