Linux Hardware: Western Digital USB3 PCIe card

We got this Western Digital USB3 card for my work computer; it plugs into the PCIe 1x slot and it worked at first boot on my Linux 3.0.0 kernel in Debian Sid.  Works like a charm, so if you've got any USB3 devices you should check out this card for a nice speed boot over USB2.

They say that USB3 is 10x faster than USB2 but I've heard that disputed; its a change in the calculations to measure the speed increase that significantly.  However, USB3 is certainly faster and due to the easy installation of this card in Linux, I'd give this device a 5/5.
