A storage system comprises: a storage device including a NAND flash memory and a storage controller for controlling the NAND flash memory, and a host device including a host controller for interacting with the storage controller and a file system for generating a read command or a write command for data pieces in the unit of blocks. At this time, when the read command or the write command for the data pieces is generated, the host device and the storage device transmit/receive the data pieces in the unit of data transmission corresponding to a sector size. When read data pieces are determined by the write command, the host device collects first space data pieces related to the write data pieces and transmits the first spare data pieces to the storage device first and then the write data pieces. |
