Product manual

Operating power and current are measured using 40% random seeks,
40% read/write mode (1 write for each 10 reads), and 20% drive inactive.
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 mode.
