StarTech has unveiled its USB 3.0 ExpressCard which features a couple of ports to get you all started with USB 3.0. But there are a few problems though. These SuperSpeed USB ports won’t have the juice to supply a full 900mA for each port.
And an optional AC adapter will be needed which adds up to more stuff to carry. The dongle itself is too vulnerable also. When laptops are dropped and land on the side of the ExpressCard, it will instantly break. At $50, you might want to think twice on this one.
