2.8Power specifications

The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 1 on page 20.

2.8.1Power consumption and DC power requirements

Power requirements for the drives are listed in the table on page 9. Typical power measurements are based on an average of drives tested, under nominal conditions, using 5.0V and 12.0V 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.

• Idle mode power

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

• Operating

Operating power is measured by simulating a typical PVR operating environment, using a 50% write 50% read algorithm.

• 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 mode.
