Hi Ken:
I just wanted to confirm since my application is a bit different. The data rate implied by your 100 Mwords per 10 min is 2.67 Mb/sec. In my case I have a much smaller 19.2 kword chunk of data but only have 3 ms to do the transfer, which works out to roughly 100 Mb/sec. This seems possible based on USB2 rates, but I take it there's something else in the mix that slows this down.
Thanks,
Roger
