Abstract:
1. A connection device capable of increasing data reading and writing speeds, comprising: a first connection module having an end connected to a computer; a second connection module having an end connected to at least one regular storage unit, each said regular storage unit having a plurality of regular storage sections; a high-speed storage unit having a plurality of high-speed storage sections and having a higher data reading speed and a higher data writing speed than each said regular storage unit; and a control module respectively and electrically connected to the first connection module, the second connection module, and the high-speed storage unit, the control module being configured for identifying each said regular storage unit and the high-speed storage unit and generating a forward mapping table for each said regular storage unit and a backward mapping table for the high-speed storage unit; and a memory unit being electrically connected to the control module and configured for storing the at least one forward mapping table and the backward mapping table; wherein each said forward mapping table has a plurality of forward fields, each said forward field corresponds to a said regular storage section, the backward mapping table has a plurality of backward fields, and each said backward field corresponds to a said high-speed storage section; and wherein each said forward field can correspond to a said backward field through a forward tag, and each said backward field can correspond to a said forward field through a backward tag, so as to enable the control module to perform a reading or writing operation in response to the computer on the high-speed storage unit first and update and confirm the corresponding data in the regular storage unit when the computer is in idle according to the forward tag and backward tag.
