2.7POWER SPECIFICATIONS

The drive receives DC power (+5V) through a native SATA power connector. See 2 on page 16.

2.7.1Power consumption

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, at 35°C ambient temperature.

• Startup power

Startup power is measured from the time of power-on to the time that the drive reaches operating condition and can pro- cess media access commands.

• Peak operating mode

During peak operating mode, the drive is tested in various read and write access patterns to simulate the worst-case power consumption.

• Idle mode power

Idle mode power is measured with the drive powered up and ready for media access commands, with no media access commands having been received from the host.

• Standby mode

During Standby mode, the drive accepts commands, but not be able to immediately access the media because the drive electronics are in a partial power-down mode.
