Disclosed is a network interface which enables a storage device to be connected to multiple networks of different specifications. A storage device is connected to a network through which communications are done in accordance with one or more communication protocols, and contains a network interface. This network interface includes a Physical Layer process unit for handling a signal defined by Physical Layer, a clock supply unit for storing information on a plurality of relations between clock frequencies and communication protocols, a serial conversion unit for determining a communication protocol, based on the information and a clock frequency of a received frame, or for determining a clock frequency of a frame to be sent, based on the information and a communication protocol of the frame, and a multi-protocol process unit for handling the frame, in accordance with the determined communication protocol.
