Design and Implementation of the High Speed and Large Capacity Solid State Storage System Based on USB 2.0

The modern information storage system,characterized by its high speed,large capacity and low cost,is one of the most important part in the application of high speed data collection.It mainly includes the control and management of the storage and the data access.The paper deals with the developing of an high speed and large capacity solid state storage system based on USB 2.0,focusing on the hardware design,the firmware design,the program coding and the way to debug USB interface.The developed system has worked properly and the average transfer speed reaches 80 Mb/s.Thus it can meet the requirements for the system design.
