The Vansuny 256GB USB 3.1 Drive puts the SanDisk Extreme Pro 256GB USB 3.2 Drive into serious competition for the world's fastest USB drive. As you can see from my Crystaldiskmark screenshots, not only does the Vansuny live up to its advertised sequential read and write requirements, it also far outperforms the flagship SanDisk drive in terms of write performance (particularly on 4K writes). I was so impressed that I bought two more. As mentioned elsewhere, you must connect this drive to a USB 3.1 port to unleash its full performance.
