Power specifications
The drive receives DC power (+5V or +12V) through a native SATA power connector. Refer to
2.7.1 Power consumption
Power requirements for the drives are listed in
tested, under nominal conditions, using 5.0V and 12.0V input voltage at 25°C ambient temperature. These power
measurements are done with DIPM enabled.
• Spinup current is measured from the time of power-on to the time that the drive spindle reaches operating
speed.
• Operating Power is measured following IDEMA 3 streams standard, assuming CE operating condition
• The drive supports three idle modes: Performance Idle mode, Active Idle mode and Low Power Idle mode.
Refer to Section 2.7.4 for power-management mode.
