When I tested USB3 performance (when I did the Z68 review, so a much older driver was used compared to now) I didn't have any issues with the performance while transferring around 2GB of data consisting of small and large files to a pen drive. I'm also making sure I stay on top of any devices Etron break support with, which is why there is now the 1.105.394.1 beta driver.

Make sure your drive is A: Connected to a SATA3 port, and B: you are using a intel SATA3 port (best performance)
