CRU-Dataport is the standard way for sending DCI-DCP’s (Films in the DCI digital format) around via Hard Drive. The CRU-Dataport system has been adopted by all (SMS) DCI-player manufacture. This allows you to plug the drive directly into the Player using ultra fast SATA interface to import/ingest the DCP onto the player. Or in an emergency, play the DCP directly of the hard drive.
