Drive Specifications
2.8 Power specifications
The drive receives DC power (+5V or +12V) through a native SATA power connector. Refer to Figure 1 on page 24.
2.8.1 Power consumption
Power requirements for the drives are listed in Table 2 and Table 3. 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.
