	Idle, low power mode*		0.72 watts	0.67 watts

	Standby**		0.40 watts

	Sleep		0.40 watts

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

**Standby power is measured at steady state (after 200ms from transition)
