The way in which I'd use that device, is ONLY as a transfer medium between the PC and the sampling circuit. It would not do anything during the sampling process. Once RAM is full, the hardware starts to shuffle the sample data from the buffer RAM into the FIFO.

Whether the transfer rate is 1Kbyte/sec or 500 Mbyte/sec matters very little. It has NO impact on the performance of the sampling logic. A serial port would work, too, but that's more bother than the FIFO. A parallel port would work, too.

The 10 MB/sec rate is the rate at which the FIFO can be loaded. The rate at which it's loaded during sampling is 0.000.

It can be used to load a trigger sequence and to monitor status if the device supports that. For now, I'd leave that for later.
