Power specifications

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

See Figure 2 on page 21 

.

Power consumption

Power requirements for the drives are listed in 

Table 2

. 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.
