ABSTRACT:
A storage device including a control part which performs control by extracting a life tag specifying a retention term during which the data is to be retained in the second volume having the quicker access time than the first volume, the control part managing the retention term of the corresponding data as specified by the life tag, and an elapsed term which has elapsed since the corresponding data was stored. A storage part manages update segment control information, and when the elapsed term of certain data exceeds the retention term of the certain data, the storage part nullifies the certain data in the second volume.
