Abstract

A storage device includes a nonvolatile memory, a communication interface connectable to a host, and a controller. The controller is configured to carry out writing of data that is received through the communication interface at a physical location of the nonvolatile memory when a write command associated with the data is received through the communication interface, control the communication interface to return a first notification upon determining that the writing of data at the physical location of the nonvolatile memory has completed, and control the communication interface to return a second notification a predetermined period of time after the first notification has been returned.
