Abstract: PURPOSE: A method for storing data in a storage medium and a data storage device including the same are provided to efficiently compress the data to be stored in the storage medium by improving an access speed for random data. CONSTITUTION: A controller(220) selectively compress data received from the outside and stores the compressed data in a storage medium(210). The controller determines a type of the data as user data or metadata for managing the user data and selectively compresses the data according to the determination result. The controller receives a logical address corresponding to the received data. The logical address points an area including sequential address values. When the received data is determined as the user data, the controller determines a compression unit of the received data according to the size of the area pointed by the logical address.

Abstract: PURPOSE: A data storage device with a data compression function is provided to determine the compression of data without a set of information which is provided from the outside, thereby improving the performance of the data storage device. CONSTITUTION: A compression ratio calculator (2120) compares the compression ratio and the target compression ratio of the inputted data. A buffer memory (2400) temporarily stores the inputted data which is transmitted through a host interface. A compression block (2500) compresses the inputted data according to a calculation result of the compression ratio calculator. A host buffer manager (2110) buffers the inputted data in order to solve the difference in transmission speed between a bus and a host which are connected to the buffer memory and the compression block, respectively. The compression ratio calculator calculates the compression ratio based on the data which is transmitted to the host buffer manager.
