I've got a usb 2.0 pci card. It's got 4 ports on the back and one single internal port. That internal port can be wired up to a drive-bay type hub on the front - or if you get tricky, rewiring your current front ports.
Typically digicams, gamepads, keyboards, mice and several other compnents don't benefit from usb 2.0. My external hard drive wouldn't be useful in the least if it was *just* usb 1.1. I haven't calculated the speed, but it's close to ide to ide had drive transfers.
