A storage system comprises: a storage device including a NAND flash memory and a storage controller to control the NAND flash memory; and a host device including a host controller to interact with the storage controller and a file system to generate a read command or a write command for data in a block unit on a logical address. At this time, if the write command or the read command for the data is generated, the host device and the storage device transmits and receives the data in a data transmission unit corresponding to a sector size and, if write data is determined by the write command, the host device collects the first spare data related to the write data, transmits first the collected first spare data to the storage device, and then transmits the write data to the storage device. |
