Abstract:
1. A data storage device, comprising: a memory device configured to store data; a host interface unit including a first host interface and a second host interface; a first signal connector configured to connect the first host interface to a first host system that physically incorporates the data storage device and used the data storage device as an internal data storage device; a second signal connector configured to connect the second host interface to a second host system that is physically separate from the first host system and uses the data storage device as an external data storage device; a connection detector disposed between the second signal connector and the second host interface and configured to detect only a connection between the second signal connector and the second host system; and a main controller incorporating the host interface unit and configure to control access to data stored in the memory device as the data storage device operates as at least one of the internal data storage device and the external data storage device, wherein the second host system is enabled to access the data stored in the memory device through the main controller upon a detection made by the connection detector of a connection between the second signal connector and the second host system.
