Abstract
An object of the present invention is to reduce deterioration in responsiveness to storage of content in a flash memory. A storage management apparatus according to the present invention includes a flash memory including a plurality of blocks each having a reserved area and a normal area, acquires a new dataset when a writable area included in a normal area of the plurality of blocks is larger than the new dataset and the new dataset is smaller in size than the writable area included in the normal area of the plurality of blocks in a case where unnecessary datasets included in the plurality of blocks are deleted, copies non-unnecessary datasets from the normal area of a specific block including the unnecessary datasets to the normal area of another block, deletes all datasets included in the normal area of the specific block, and stores the new dataset in the normal area of the specific block from which all the datasets are deleted.
