Power specifications
The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 4 on page 20.
2.5.1
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
