sequentially acquiring the size of a data block and the number of data blocks stored in each data in the first array;
sequentially storing the data to be stored into the first array according to the size of the obtained data blocks and the number of the obtained data blocks;
and in response to the first array failing to store all the data to be stored, storing the remaining data into the first array when the first array is updated.
6. The method of claim 1, wherein storing each data in the first array to an address corresponding to an area in the second array comprises:
reading the data block size and the data block number of first data which is not stored in the first array;
reading one data in the second array to obtain an area where the data is to be stored;
generating a random number based on the read area to be stored, and aligning the random number and the size of a first data block obtained by reading;
and taking the random number as a starting logical address of data storage, and writing first data which is not stored into the read area to be stored.
