In accordance with an aspect of the invention, a storage system comprises a processor; a memory; a disk control module configured to receive a write command for writing to an unallocated area and to identify an object of the write command to be written as a written object; and an object allocation acquisition module configured to obtain object allocation information specifying one or more virtual volume locations for storing the written object. The disk control module allocates, to each of the one or more virtual volume locations, an area selected from a plurality of logical volumes if the written object is predefined as a randomly accessed object. The disk control module allocates to the one or more virtual volume locations a consecutive area of one logical volume if the written object is predefined as a sequentially accessed object.
