A method for distributing log block associativity in log buffer-based flash translation layer (FTL) includes, if write request on page p is generated, checking whether log block associated with corresponding data block that write request is generated exists or not by checking log block mapping table storing mapping information between data blocks and log blocks, wherein the associativity of each log block to data block is set to equal to or less than predetermined value K in advance, and K is a natural number, if log block associated with corresponding data block that write request is generated exists, checking whether associated log block is random log block or sequential log block, and if associated log block is random log block, writing data that write request is generated in first free page of random log block. |
