When the size of the data to be stored is 16KB, storing the data to be stored in a second storage block, and when the size of the data to be stored is not more than 16KB, storing the data to be stored in a storage page of a first storage block, wherein LBAs of data not stored in the storage page are filled by invalid data FF, and the data to be stored is valid data. And when the total amount of valid data stored in a first storage block reaches 16KB, transferring the valid data stored in the first storage block to the second storage block. According to the storage scheme, the data in each storage page of the second storage block can be guaranteed to be valid data, and invalid data is not required to be filled, so that the capacity of one storage page can be achieved, each storage space is fully utilized, the utilization rate of the storage space is improved, and the occupation of the invalid data on the storage space is reduced.
