    Abstract: PURPOSE: A method, a system, and computer recording medium are provided to maximize the performance of a storage device having high speed by omitting scheduling processes for an input or output request. CONSTITUTION: A file system(110) determines a free tag on a command waiting line of a storage device(150). When there is the free tag, a rapid path input-output module(120) directly transmits an input or output request to the storage device. When there is not the free tag, a scheduler block(140) schedules an input or output request. A slow path input-output module(130) transmits the scheduled input or output request to the storage device. When there is not the free tag in real, a rapid path input or output module transmits the input or output request to the schedule block.

    Abstract: PURPOSE: A method, a system, and a computer-readable recording medium for searching the position of metadata are provided to find out the position of metadata through a single access to a storage medium, thereby using a maximum performance of a rapid storage medium. CONSTITUTION: A storage device (420) has a metadata area for storing metadata of a file. A file system (410) performs hashing of a specific file based on file name or file path of the specific file, obtains an address of the metadata of the specific file, and performs metadata read or write of the specific file at the address of the metadata area. The file system performs a first hashing that receives the file name or the file path as an input and outputs a hash key and a second hashing that receives the hash key as an input and outputs the address.
