I have one of those, a Lexar S55 that gets burning hot during USB3 transfers. Data transfer is fast for a little while, then suddenly slows down as the buffer is filled or a built-in temperature sensor throttles it back. Oddly enough, a 32G S75 goes as fast but gets only warm. It might still work on a USB2 port, if it is a thermal issue.
