The drive receives DC power (+5V) through a native SATA power connector. See Figure 2 on page 19.
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 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.

*During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase power to operational levels.
