The host device comprises an interface which transmits and receives data to a storage device which stores a multi-level hash table having the directory entry of each directory and the directory entry which receives a file look-up command in which a search directory and a search file name are designated, which calculates a hash value applying the search file name and a check level, and which searches the directory entry comprising the search file name in a bucket which corresponds to the hash value among the bucket of the check level included in the multi-level hash table. The file system module is provided to increase the check level when a search is failed, thereby calculating the hash value and searching the search file name again.
