2.8.1
Power 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 process 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.
