Abstract
A writing method for a solid state disk is disclosed. The method comprises following steps: A writing unit is arranged in a buffer memory, wherein plane addresses of the writing unit are in one-to-one correspondence with non-volatile memories of the solid state disk. A writing data is received. A reordered plane address of the writing unit is obtained by using the residue of the logical allocation address of the writing data dividing the plane address number. Whether the reordered plane address is empty is checked. If the reordered plane address is not empty, the next plane address is shifted and the plane address is reordered. If the reordered plane address is empty, the writing data is buffered to the reordered plane address and the logical allocation address of the writing data is arranged in order.
