This is a very interesting product because it's the first USB hub that supports the 10 x higher speed, dual simplex data transfer (basically multitasking with USB 3) and GIGABYTE's 3x USB power. Essentially this means that you can power/run more devices from a single USB port.
Here are the numbers: USB 2.0 power is around 2.5W (5v x 0.5A), but GIGABYTE triples the amperage to 1.5A so it is 7.5W on GIGABYTE USB 3.0 motherboards. USB 3.0 power is around 4.5W (5v x 0.9A) but on GIGABYTE USB 3.0 boards it is 13.5W (5v x 2.7A). That's a significant power boost if you ask me and a USB 3.0 hub is just the device to take advantage of more power! Read more here.
