When we designed our 128GB Corsair Flash Voyager GT USB flash drive we expected that we would end up with a pretty high performance USB flash drive on our hands. We designed it bottom-up for speed by using a rather novel dual-controller architecture, in an attempt to bypass some of the limitations of the UFD controllers that were in production at that time.

We didn’t realize JUST how fast it was, though, until we tested it against some competitive 128GB USB flash drives. We ran both synthetic benchmarks and real-world tests to determine how we did against the competition. And, we were pretty pleased with the results!
