    Well, just like a chain, it is only as strong as it's weakest link. So if you go from USB 2 to USB 3 with an adapter, it will only be as fast as it's slowest link, which will be USB 2.

    USB 3 is backwards compatable. So if you plug a USB 3.0 device into a MBP, it will just run really slowly (USB 2.0 speeds).

    How much faster ( xpressed as a percentage) is 3.0?

    USB 3 is about 10 times faster than USB 2. Google helped me find that answer.

    Also check out this page:

    SuperSpeed USB 3.0 FAQ

    Just remember, Mac's do not have USB 3. So if you plug a USB 3 device into a Mac, it will only run at USB 2 speeds.

    I know that Usb 2.0 is better than 3.0 and it is speedy.

    Hopefully this little diagram I drew up will help you understand it better. USB2 to USB3 adapter would be pretty much useless simply because USB3 interface is already backward compatible with USB2, it'll just be bottlenecked by slower USB2 speeds.

    It is my hope -and I bet others- that somebody will come out with a TB to USB3 adapter.

    Have seen Sonnet 34 express card advertised to work in Mac 17" express card slot for going to usb 3.0. Has any actually tried that one yet and did it actually work?
