16. A storage device comprising:
a memory that stores data;
a controller configured to control writing of data to the memory and reading of data from the memory;
an interface unit that includes a first terminal, a second terminal, and a third terminal,
the first terminal having an electrical status different between a case where the first terminal is connected to the first device, and a case where the first terminal is connected to the second device,
the second terminal being a terminal to which a control signal is input from the second device,
the third terminal being a terminal through which power is supplied from the second device to the storage device;
a switch configured to switch a connection status and a disconnection status based on the control signal, the connection status representing a status in which the third terminal and the controller are electrically connected, the disconnection status representing a status in which the third terminal and the controller are electrically disconnected; and
a switch control unit configured to control the switch to switch the connection status and the disconnection status based on electrical statuses of the first terminal and the second terminal.
