Power specifications
The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 3 on page 24.
2.5.1
Power consumption
Power requirements for the drives are listed in Table 3 through Table 5. 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.
