Ordinary usb flash drives are easy enough to get, and cheap. I should probably just try those (planning on 2 in raid). I'm not using them for anything GUI; the one I have running atm is an openvpn endpoint. There are many Sandisk and other options - I guess my main consideration is something slim enough that I can fit two in adjacent ports. Thanks, Richard
