    Some modern hard drives transparently encrypt all data with an internal key, which can be erased with a special secure erase command. Comes in handy for wiping drives without spending hours overwriting the enire disk.

      How does a hard drive include enough processing power to encrypt/decrypt things without having any impact on read/write times?

        What do you mean? Even a $1 microcontroller can do stuff like that nowadays.

        The hardware variants have a chip onboard that can do that when the user enables it. Hence essentially no impact on performance.
