USB 3.0 is just around the corner, with us having reported about more and more compatible devices in the last few months. And today, Tokyo-based Greenhouse, usually a reliable maker of crap gadgets, announced [JP] a USB 3.0-compatible PCI Express interface card.

Greenhouse says the maximum data transfer rate stands at 5Gbps (see the chart below), but take that with a grain of salt. The card is compatible with Windows XP, Vista and 7 machines.

It will go on sale on Greenhouse’s Japanese web site in the next few days for $40.
