Abstract

This invention relates to a data storage device and, more particularly, to a data storage device with flexible serial connection function. The data storage device includes: a mode detector for detecting whether an external device connected to an output connector thereof is a primary mode setting circuit of a host system, and for controlling a mode switch unit to selectively switch to a primary mode or a secondary mode; a data read/write controller for constantly detecting whether an external expansion connector is serially connected to another external data storage device, if affirmative, the host system being alerted by the output connector, such that the host system is able to selectively switch to a summing mode in which the storage capacities of the storage media within all serially connected data storage devices are integrated and summed up in response to the newly added external data storage device, or to a plug-in mode in which the serially connected external data storage device is deemed as a plug-in data storage device. As such, this invention is able to not only integrate the memory capacities of all internal storage media, but is also expand its applicability.
