An optimized design of a storage system based on SATA3.0

Abstract

Aiming at the problem of real-time storage of high resolution, high frame frequency and large capacity image data obtained in telemetry test, as well as the problem of transmission stability, we optimized a storage system. This system takes 7 series FPGA as the control core, and stores the received large-capacity image into the solid state hard disk through SATA3.0 transmission bus. The state machine is optimized in the stored procedure to solve the problem of transmission interruption through the real-time marker monitoring.After the storage was completed, the data in the SSD will be read through the gigabit Ethernet to the computer for playback and analysis.Lots of reading and writing data were completed at room temperature and -40 ℃ and +60 ℃. The results show that the optimized storage system can achieve high speed and long time stable storage and has a good reference value in large capacity storage.
