Considering that the ground test equipment for space cameras has the characteristics of large amount of data and rapid storing velocity, the design of a high-speed large capacity storage system is implemented by using FPGA as the control core and the solid NAND Flash with excellent performance as a storage medium. To improve the storing velocity of the system, the Flash array is controlled by using two-plane operation, parallel technology and pipeline technology. The system uses bad block management after analyzing bad block feature of Flash. Experimental results show that the system can accomplish the record of a large number of high-speed original data from space camera, which ensures the real-time performance and reliability of data recording.
