Hardware-based solid state disk read command automatic integration method and system

The invention discloses a hardware-based solid state disk read command automatic integration method and system, and the method comprises the steps: S1, obtaining read commands sent by a host, carrying out the priority classification according to the obtained read commands, and selecting the classified read commands; s2, segmenting the selected read command based on a mapping table single reading unit to obtain segmented read command fragments; s3, querying the obtained read command fragment based on a mapping table to obtain a read command physical target address; s4, identifying a page boundary of the physical target address of the read command in the flash memory, and segmenting the read command again according to the page boundary; s5, putting the read command segmented according to the page boundary into a re-integration buffer area for integration; s6, re-integrating the read commands which hit the same flash memory page in the re-integrated cache region according to conditions; and S7, executing the ste
