Well, my current setup is using an old 2GB CF card, so read/write speeds suck (14 and 7 MB/s, respectively, IIRC), but then again, there are not many actual read/writes on / or /usr for my setup anyway. The 2x 8GB USB sticks I would of course use to gmirror the setup, although I have been told that this is rather excessive. Modern flash media should cope with enough write cycles to get you through a decade. With /var being on GELI+ZFS this point is mood even more, IMHO. A recent 8GB Sandisk U3 stick of mine manages to read/write ~25MB/s (working from memory here), so this is pretty much the maximum USB 2.0 is giving you.
