USB 3.0 and SATA 3

One of the most used subsystems would be the SATA controller. I put both the SATA 3 controller and the USB 3.0 controller to the test using the same SSD to see the performance difference between the two. While the USB 3.0 numbers are actually very impressive, its obvious that it is still a bottleneck compared to the performance that SATA 3 and here soon SATA Express are capable of. Some manufactures have worked on tuning USB 3.0 performance for higher transfer speeds but MSI went with the stock Intel chipset performance that is  still more than capable.
