2.7.1Power consumption

Power requirements for the drives are listed in the table on page 8. Typical power measurements are based on an average of drives tested, under nominal conditions, using +3.3V input voltage at 25°C ambient temperature.

Spinup power

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

Seek mode

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, at the moment while the head is writing/reading from/to disc. It is performed with 100 percent duty cycle of write/read operation.

Low power idle mode

Spindle motor is working normally with actuator unloaded to the parked position.

Standby mode / Sleep 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 mode.
