A data storage method and a storage device. The method comprises: receiving a write command; if the received write command contains the logical address of data to be stored, parsing the received write command and converting same to storage medium write commands; cutting data to be executed in each of the storage medium write commands into several data blocks; sending a data reception request to a host, and transmitting data in the host to a pre-applied first cache unit; after writing of data of the first cache unit is completed, starting a data write process from the first cache unit to a storage medium, simultaneously applying for a second cache unit for each data channel for carrying out data transmission, and starting data transmission from the host to the second cache unit; and after the data of the first cache unit is completely written in the storage medium, releasing the first cache unit, and repeating this cycle until transmission of all data blocks is completed. The read and write performance of a storage device can be improved by the method.
