USB 3.0 Performance:
Benchmark Results: With Crystal Mark v2.2 was run with a file size of 100MB and we saw a healthy increase going from a USB 2.0 interface to SuperSpeed USB 3.0. The 4K random read and write performance didn’t budge, but the sequential write test showed that performance increased by 4x what we saw using USB 2.0!
