Power specifications
The drive receives DC power (+5V or +12V) through a native SATA power connector. (Refer to
2.8.1
Power consumption
Power requirements for the drives are listed in
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 (CE profile)
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.
