An apparatus comprising a single memory device providing data storage, a controller for controlling data transfer to and from the data storage, and first and second bus connector plugs, wherein each plug has contacts for connecting with the power, ground, and data contacts of a port of a host system. The power and ground contacts of the first and second plugs are coupled together to provide power to the apparatus through either or both plugs. Data from either or both plugs is communicated with the controller depending upon which plugs are coupled to a port. The controller is responsible for controlling the read and write operations of the data storage. The apparatus may be any type of external memory device, such as a flash drive, or a peripheral device having a high data transfer rate, such as a digital video camera.
