Abstract
A RAID system and method based on a solid-state storage medium. The system includes a plurality of solid-state storage devices and a main control unit. Each solid-state storage device includes a solid-state storage medium and a controller for controlling reading and writing of the solid-state storage medium. The main control unit is electrically connected to the controller of each of the solid-state storage devices in a RAID array. The main control unit is used for performing address mapping from a logical block address in the RAID array to a physical block address of the flash memory solid-state storage device. The address mapping and the RAID function can be integrated to solve the problems of write amplification and low performance. The unified management of address mapping of the solid-state storage devices can be implemented to improve the efficiency of garbage collection and wear leveling of the solid-state storage system.
