When I transfer data, I use a very simple and relatively fast connection via GPIO and Labview. For that you need a Labview card and box (expensive but in most university labs available) with digital I/O pins and a clock input. Then you connect the I/O pins from Labview to some pins of the GPIO port.

The transfer rate is 1Mbit/s for each connected data pin with my labview card.
