Looking to buy a U3 drive to try the Hacksaw as part of a class project (no ill intentions). I went to some online stores, but drives don't list if they are U3 or not. Would the packaging for the USB drive at the store state this? I'm probably going to roll to Best Buy and pick up a 512 or 1GB since it's for the class only. Any recommendation/suggestions on some that may work better than others or is it irrelevant? Thanks in advance for helping the "Noob"
