Seagate Exos 7E10 Serial ATA Product Manual, Rev. B 12
2.5 Power specifications
The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 2 on page 24.
2.5.1 Power consumption
Power requirements for the drives are listed in 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 35°C ambient temperature.
* During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic
and power to operational levels.
