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
• Peak operating mode
During peak operating mode, the drive is tested in various read and write access patterns to simulate the
• 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
