Some are definitely quicker than others... I'd highly recommend the 64GB Corsair Slider USB3.0 it easily saturates USB2.0 ports and a healthy 70MB/s write, 85MB/s read USB3.0, all going well, lol.I'd keep an eye out for refurbished ones as they are A LOT cheaper:http://www.mymemory.co.uk/USB-Flash-Drives/Corsair/Corsair-64GB-Flash-Voyager-Slider-USB-3.0-Flash-Drive----Refurbished-
