    Guangxin,

    6.4Gsps is not possible. The max practical USB3.0 throughput possible is only 2.7Gbps to transfer the data to PC RAM without any post processing. Writing to hard drive and any channel specific data post processing will add additional overhead to this.

     

    You can try to utilize the whole DDR memory on the board to get a huge real time capture then transfer the memory to PC in non-real time manner.

    Regards,

    Jim
