Abstract: A storage device relating to one aspect of the present invention has a storage controller and multiple memory devices. The memory devices manage capacity equivalent to the size of a memory space provided to the storage controller among regions of a non-volatile storage medium as logical capacity and manage the remaining regions as reserve capacity. When a device controller determines that a portion of the memory regions in the non-volatile storage medium is in an unusable state, the device controller notifies the storage controller of the size of the memory regions in the unusable state. On the basis of a policy set by the memory device, the storage controller determines the reduction amount of the logical capacity and the reserve capacity and notifies the memory device of the determined reduction amount of the logical capacity.
