Hi,

   

It would be good to get an idea  of what data rate people are seeing with the FX3. To help with this I've created a list below
which arranges recorded data rates along with the user name. At the moment Chris_R  is at the top, numero uno,  on 320MBs while I am  second / last on 127MBs - but I plan to improve. If you have carried out any bandwidth tests and would like to share the results please add your name to the list along with the data rate and direction.
Thanks

For your information: The speed of 320MB/s upload I reached using 100MHz PCLK, 16 Packets per Burst, Auto DMA Mode, AMD mainboard with integrated PCIe 2.0 USB SuperSpeed Host (NEC) and Windows 7 x64 using WinUSB driver. Download speed war ~260MB/s.
