I think these are ment for running a OS from.

But still, if USB 2 is holding UDMA cards back? (is it?) then could this help speed up transfer? ... adsacf.asp

i have a couple of ESATA external hard drives and in practice they transfer data about 4 times as fast as usb 2.0

USB2 has a max transfer speed of 480 Mbps, which translates to about 60 MB/s. The real kicker is that USB2 requires CPU power to do the transfers, so you should see your CPU usage spike when doing any intensive file transfers. This is why Firewire 400 is rated "slower" at 400 Mbps, in practice it is faster than USB2 because the transfers bypass the CPU.

ESATA is definitely going to be better than USB2 so I'd get an ESATA CF reader if possible.
