A high-speed large-capacity embedded storage system based on SATA

The paper analyzes the problems and defects of traditional data storage systems and SATA storage and put forward a new system for the applications of embedded high-speed storage system by two steps: First, the system carry out improved SATA storage channels on embedded applications background. Second, the system established control and data distribution module through real-time switching mechanism against rate decreased drastically that affect system stability issues when write to SATA channels. The control and data distribution module established by two steps: ķIndirectly detect SATA channel data rate steep drop by inspecting cache. 1) Decide whether to switch the storage group or not when fine a steep drop or the block of data has been store into the storage medium. The control and data distribution module could action as load balancing mechanism module while solving the write data rate steep drop of SATA channels, the architecture of which support the bandwidth and capacity of the storage system to expansion expediently. Experiment validated real-time adaptive switching mechanism resolve the non-steady state of the system, which resolves the memory bandwidth bottleneck and the question of storage versatility.
