Abstract
A writing method for a solid state drive is provided. Firstly, a buffer is divided into plural buffering regions corresponding to plural data streams. Then, the write command is received from a host, and a write data corresponding to the stream information of the write command is stored into the corresponding buffering region of the buffer. Then, the write data in each buffering region of the buffer is divided into plural groups according to a program data amount. Then, one program command is assigned to each group in each buffering region, the program command and each group are combined as a job, and the job is listed in a stream job link list. Afterwards, the jobs corresponding to each data stream are transmitted to a non-volatile memory according to a content of the stream job link list.
