Drive Specifications

2.7

Power specifications

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

Figure 2 on page 18

.

2.7.1 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. 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.

2.7.2 Conducted noise

Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on the +12 volt
line or an equivalent 15-ohm resistive load on the +5 volt line.

• Using 12-volt power, the drive is expected to operate with a maximum of 120 mV peak-to-peak square-wave injected

noise at up to 10MHz.

• Using 5-volt power, the drive is expected to operate with a maximum of

100 mV peak-to-peak square-wave injected

noise at up to 10MHz.

Note

Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current.
