Abstract
A storage device includes a memory and a control device. The control device allocates a first storage region out of a plurality of storage regions to a first logical address specified by an external device. The control device stores, in the memory, first information associating the first logical address with a first physical address indicating the first storage region. The control device deletes, upon accepting a request for release of a second storage region indicated by a second physical address associated with a second logical address specified by the external device, second information associating the second logical address with the second physical address from the memory. The control device releases, when copy process of copying first data stored in the second storage region is unexecuted, the second storage region after finishing the copy process.
