High Performance USB 3.0/3.1 Portable Flash Memory Drives

The latest revision of the USB standard, version 3.1, doubles the theoretical speed from 5Gbit/s or 625MB/sec to 10Gbit/s or 1,250MB/sec, meaning much quicker data transfers when copying files to and from a USB device such as a pendrive. USB 3.1 devices are backwards compatible with USB 3 and USB 2 ports, but you'll need a motherboard or add-in card that supports USB 3.1 to get the full advantage of the new standard.
