If so, you should be aware that flash RAM has a limited life in terms of write/erase cycles. This is usually a fairly high number, and most people will never reach it with a USB memory device. Using it for swap would probably be a different matter, especially if your machine is swapping a lot. You may find after a while that you have dead flash RAM.
