DC power requirements
The voltage and current requirements for a single drive are shown below. Values indicated apply at the drive connector.
The standard drive models and the SED drive models have identical har dware, however the security and encryption portion of the drive
controller ASIC is enabled and functional in the SED models. This represents a small additional drain on the 5V supply of about 30mA and
a commensurate increase of about 150mW in power consumption. There is no additional drain on the 12V supply.
