Seagate ST1000VX000 ユーザーズマニュアル

The drive receives DC power (+5V or +12V) through a native SATA power connector. Refer to 

 and 

. Typical power measurements are based on an 

average of drives tested, under nominal conditions, using 5.0V and 12.0V input voltage 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.

• Read/write power and current

Read/write power is measured with the heads on track, based on a 16-sector write followed by a 32-ms delay,
then a 16-sector read followed by a 32-ms delay.

• Operating power and current 

Operating power is measured by simulating a typical PVR operating environment, using a 50% write, 50%
read algorithm.

• 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 mode.

 

* 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.
