Abstract
The invention provides a data storage system. In one embodiment, the data storage system comprises a host and a flash storage device. The host sends a series of first access commands for accessing a plurality of special files to the flash storage device. The flash storage device having the stored plurality of special files and a command-symbol mapping table, sequentially generates a plurality of first digits respectively corresponding to the special files accessed by the first access commands to obtain a first data stream, converts the first data stream to a plurality of first special commands according to the command-symbol mapping table, and performs operations according to the first special commands. Each of the special files corresponds to a digit, the command-symbol mapping table records a corresponding relationship between a plurality of symbols and a plurality of special commands, and each of the symbols comprises a plurality of digits.
