2.7Power specifications

The drive receives DC power (+3.3V) through the ZIF connector (IDE interface).

2.7.1Power consumption

Power requirements for the drives are listed in the table on page 7. Typical power measurements are based on an average of drives tested, under nominal conditions, using +3.3V input voltage at 25°C ambient temperature.

•Startup mode

Startup 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 power is measured based on three random seek operations every 100 msecs.

•Read/write mode

Read/write power is measured with the heads on track, while the head is reading/writing from/to disc. It is performed with 100 percent duty cycle of read/write operation.

•Performance Idle mode

During Performance Idle mode, the heads are on track but no reading or writing is done. The spindle motor is spinning at full speed.

•Low power idle mode

During Low power Idle mode, the heads are unloaded but the spindle motor is spinning at full speed. Servo and read/write electronics are in powered down mode.

•Standby / Sleep mode

During Standby/Sleep mode, the spindle motor is not spinning, and the servo and read/write electronics are in powered down mode.
