Table 3:	DC power requirements

Power dissipation (3-disc values shown)		Avg (watts 25° C)	Avg 5V typ amps	Avg 12V typ amps

Spinup		—	—	3.0 (peak)

Idle*		7.96	0.320	0.530

Idle* (with offline activity)		9.29	0.610	0.520

Operating (40% r/w, 40% seek, 20% inop.)		11.16	0.600	0.680

Seeking (random, 20% idle)		10.42	0.500	0.660

Standby		0.99	0.150	0.020

Sleep		0.99	0.150	0.020

*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.
