USB 3.0 speed. USB 2.0 compatibility. Flash Voyager durability. As fast as USB flash drives are, copying files always seems to take a little longer than you’d like. The advent of the USB 3.0 interface puts an end to that. You can move files back and forth in a fraction of the time it takes with standard USB 2.0 flash drives, and the proprietary water-resistant rubber housing helps keep those files safe.
