Abstract
A self encryption drive (SED) receives a media encryption key (MEK) from a key management server. The MEK is stored only in volatile memory of the SED. Data is encrypted for storage in a non-volatile storage media of the SED based on the MEK. Further, the MEK is erased in the volatile memory to crypto-erase the SED by deleting all instances of the MEK stored by the SED.
