A computing system a storage device and a file system. The storage device includes a storage area having flash memory. The file system is configured to divide the storage area into multiple zones, multiple sections and multiple blocks, and to write a log in each block. The file system includes a block allocation module. The block allocation module is configured to allocate a target block, in which a log is to be written, by a continuous block allocation method according to which a block having a continuous address with a most recently selected block is set as the target block. The block allocation module is further configured to find a free section from the multiple sections when it is not possible to allocate the target block by the continuous block allocation method, and to set a block in the found free section as the target block. |
