PROBLEM TO BE SOLVED: To suppress data fragmentation due to rearrangement of data blocks to a hierarchized disk.SOLUTION: In a storage system 1 including a storage device 10 including a hierarchized disk 11 and an information processor 20 for accessing the storage device 10, the storage device 10 notifies the information processor 20 of block information including a storage positions of data blocks included in each file stored in the hierarchized disk 11, the information processor 20 determines an access mode of the data blocks on the basis of access mode information of each file to be used by an application 211 for accessing the hierarchized disk 11, and the block information of each file notified from the storage device 10, and the storage device 10 rearranges data blocks to the hierarchized disk 11 based on an access mode of the data blocks determined by the information processor 20. |
