A storage device 110 includes: a data writing part 111 configured to store data to be written into a storage device 120 and also, when storing other data of the same content as the data already stored in the storage device into the storage device, refer to the data already stored in the storage device as the other data; and a data separating part 112 configured to separate data to be written into a user data portion and a management data portion that are classified in accordance with a previously set criterion. The data writing part 111 is configured to store the user data portion into a user data file 121, store the management data portion into a management data file 122, and store the user data portion and the management data portion separated by the data separating part 112 into the storage device 120.
