Portable storage device with multiple data interfaces

A portable storage device with multiple data interfaces coupled to an electronic device for performing data access, said portable storage device comprising:

• a casing, wherein said casing contains a cavity, and a first opening and a second opening are located in both sides of said casing;
• a circuit board, wherein said circuit board is placed in said cavity and contains a memory device used for performing data access;
• a first data interface, wherein one terminal of said first data interface is electrically connected to said circuit board and the other terminal of said first data interface is coupled to said electronic device for performing data access;
• a second data interface, wherein one terminal of said second data interface is electrically connected to said circuit board and the other terminal of said second data interface is coupled to said electronic device for performing data access;
• and
• a movement unit, wherein said movement unit reciprocates to slide on an outer surface of said casing along an axis formed between said first opening and said second opening to make said first data interface protrude out of said casing via said first opening or to make said second data interface protrude out of said casing via said second opening, wherein said first data interface and said second data interface are all stored inside said casing simultaneously in one operation state.
