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 disc 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 100 msecs. 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 100 msecs.

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

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.
