A computing device supporting ordered mode journaling. The computing device includes a memory that stores a program for operating a file system supporting ordered mode journaling; and a processor that operates the program stored in the memory. Wherein during execution of the program, when ordered mode journaling for a transaction including one or more files is implemented, the processor stores the transaction in a data area of the memory, and implements the journaling by storing a common journal including metadata of the transaction in a journal area of the memory.
