Abstract: A storage device comprises a nonvolatile memory configured to store data that is written in size units of a mapping size, and a storage controller configured to transmit a command to the nonvolatile memory. The storage controller includes a host interface configured to receive a write command from a host device, the write command including a command to write first data to a first address, the first data having a first size smaller than the mapping size. The storage controller includes processing circuitry configured to transmit a read command to the nonvolatile memory, to cause the nonvolatile memory to read second data stored in the nonvolatile memory addressed based on the first address, in response to a determination that the first size is smaller than the mapping size and before the first data is received at the storage controller through the host interface.
