SV35.5 Series SATA Product Manual, Rev. C

The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 1 on page 20.

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, 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.

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

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

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.
