The invention relates to an external sorting method and device for SSDs, computer equipment and a storage medium. The method comprises the steps that small files read into a memory are obtained, the small files are ranked to obtain an ordered intermediate result, the ordered intermediate result is written back into a flash memory, and the small files are obtained by segmenting large file data; according to the minimum value of each data page in the ordered intermediate result and the position information of the data pages on the flash memory, constructing an index table in the memory of the SSD; the index table comprises index information corresponding to the position information; and during data merging, sorting the index table according to the minimum value of the data page, performing data merging according to a sorting result of the index table and the index information to obtain an ordered result, and writing the ordered result back to the flash memory. By adopting the method, the read-write multi-channel concurrency of the SSD can be improved, and the channel resource utilization rate of the SSD can be improved.
