Hello,

The usb spec lists the achievable bandwiths for many scenarios. These 
are realistic as far as the usb bus is concerned.
In practice the combination of the usb controllers on the host and the 
host operating system often limits the bandwith.
This seems to be getting better so you should use a recent mainboard. 
Maybe you can even find chipset tests that can
give you information which chipset achieves the highest throughput with 
the least cpu load.

A development board with a usb 2.0 phy starting at 92€ is
