To provide a storage system capable of cutting back the resource while obtaining a WORM function. In the storage system, a controller ( 110 ) functions to: obtain, when a write request is made by a computer ( 300 ), information on one of logical devices that is a target of a write process, from a memory module ( 140 ); and inform, when the logical device is set to unwritable, a signal indicating that the logical device is set to unwritable, to the computer ( 300 ). An interface ( 200 ) functions to: reference meta-information held in a disk drive ( 130 ) to obtain a list of files that are not accessed for a predetermined period; secure a logical device that is capable of storing the files on the obtained list of files; and cause the controller ( 110 ) to store, in the logical device, the files on the list of files and set the logical device that stores the files in a manner that makes information stored in the memory module ( 140 ) unwritable.
