cause it took a long time to download 32GB Sandisk ExtremePro NEF (Raw) data with USB 2.0, I decided to get the Lexar CompactFlash Reader (Firewire 800).
Recieved it last friday, and the performance is amazing. It is really worth the around 60€.
So now I do not download from the camera, for CF cards I use the Lexar instead.
Just for those who might be insterested.
