2.8Power specifications

The drive receives DC power (+5V) through the 4-pin power connector.

2.8.1Power 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 25°C ambient temperature.

•Spinup power

Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed.

•Seek mode

During seek mode, the read/write actuator arm moves toward a specific position on the disc surface and does not execute a read or write operation. Servo electronics are active. Seek mode power is measured based on three random seek operations every 100 msecs. This mode is not typical.

•Read/write power and current

Read/write power is measured with the heads on track, based on three 63 sector read or write operations every 100 msecs.

•Idle mode power*

Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads in a random track location.

•Standby mode

During Standby mode, the drive accepts commands, but the drive is not spinning, and the servo and read/ write electronics are in power-down model

Table 3:	DC power

Power dissipation		+5V average (25° C)

Spinup (typical)		1.0 Amp

Seek, random r/w, desktop usage
PATA		2.3 Watts
SATA		2.9 Watts

Idle*
PATA		1.95 Watts
SATA		2.5 Watts

Standby and sleep modes
PATA		≤ 0.25 Watts
SATA		≤ 1.15 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.
