About time companies started releasing USB 3.0 adapter solutions, same bandwidth as a PCI-E 2.0 x1 slot means we can actually get full speeds out of the device. Unlike the USB 2.0 versions which claim to be connected at 867Mb/s when the interface tops out at 480Mb/s, that makes a whole lot of sense, right?
Not to mention there is absolutely no downfall of just releasing anything USB in the USB 3.0 spec as it is backwards compatible with USB 2.0 ports.
