Abstract
A storage device includes nonvolatile memories and a controller. The controller previously manages a correspondence relationship between physical addresses indicating the memory regions and stream identifiers, before first write data is received by the controller. The controller controls the nonvolatile memories such that the first write data is stored in a first memory region of a physical address which is managed corresponding to a first stream identifier of the first write data in the correspondence relationship. The first write data is transferred to the nonvolatile memories based on the correspondence relationship, regardless of whether second write data having a second stream identifier is received by the controller.
