Power specifications
The drive receives DC power (+5V and +12V) through a native SATA power connector. See Figure 4 on page 25.
2.5.1
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.
Operation at 3 Gb mode reduces the +5V supply load by 3mA with a commensurate power reduction of 15mW.
There is no measurable impact to the 12V supply load when running at lower interface speeds.
