<p>PROBLEM TO BE SOLVED: To provide an external contact type storage device and its driving method.SOLUTION: An external contact type storage device 1 includes: a hard disk 10, a control unit 12, a bridge unit 14, a connection port 16, and a voltage conversion circuit 18. The control unit 12 connects with the hard disk 10, and the unit is used to match so that the hard disk 10 becomes a disk array. The bridge unit 14 connects with the control unit 12 and changes an USB signal to be a SATA signal. The connection port 16 connects with the hard disk 10, and the voltage conversion circuit 18 connects with the control unit 12 and the bridge unit 14. The external contact type storage device 1 receives power supplied by an electronic device 9 through a transmission line 20, and the power drives the hard disk 10 by transmitting directly to the hard disk 10 via the connection port 16, and the voltage conversion circuit 18 converts the power and supplies to the control unit 12 and the bridge unit 14. Thus, the external contact type storage device 1 does not need to externally contact with a power supply device and a transformer, and is excellent in convenience of portability.</p> |
