EXTERNAL STORAGE DEVICE AND DRIVING METHOD THEREOF

摘要

An external storage device comprises a plurality of hard disks, a bridging control unit, a connecting port and a voltage converter circuit. The bridging control unit is coupled to the hard disks and ingrates the hard disks into a redundant array of independent disks. The connecting port is coupled to the bridging control unit and the hard disks. The voltage converter circuit is coupled to the bridging control unit and the connecting port. The external storage device receives through a transmission line a power supplied from an electronic device. The power is transmitted through the connecting port directly to the hard disks in order to drive the hard disks. The voltage converter circuit converts the power and supplies the power to the bridging control unit. It is convenient for user to disconnect an extra power supply apparatus and a voltage transformer.
