connector.
The standard drive models and the SED drive models have identical hardware, 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.
