I suppose I would try pretty much what you have mentioned. I sometimes use usb drives, but as you said are slow - and some of mine are SLOW, SLOW, SLOW as I still have some usb 1 left.
Recently, I bought an inexpensive Toshiba laptop. I picked it over several alternatives, because it had one of those USB/SATA ports built in. I use it with a normal full size hard disk (large capacity) in a case that requires external power. It is a pain to carry, but the performance is great. Couldn't be more pleased with it - although it would be even better if I used a laptop disk and got my power from the PC some way. (By the way, I used to use a passport drive that used two usb connectors - one for the signal and one for power.)
