Not that USB 3.0 will be useful anytime soon—how long did it take manufacturers to finally get behind USB 2.0?—but Asus’ U3S6 should be, provided it’s not cancelled, the world’s first USB 3.0 + SATA 6.0 PCI-E card. Better news: it’s only $30.

The card comes with two USB 3.0 ports and two SATA 6.0 ports. And if I’m doing my maths right, so long as you have a free PCI-E slot you’re good to go.

Like I said in the beginning, the card will mean little in the immediate future, given the lack of USB 3.0 products. That’s not to say I wouldn’t mind being able to sync my Zune HD using the zippy awesomeness of USB 3.0, but it’s going to be a little while before we see that. Never mind that that scenario would never happen, considering the Zune HD’s insides don’t know a darn thing about USB 3.0, but you know what I mean: a future media player that works with USB 3.0 would certainly be handy, especially as we move toward moving higher and higher resolution video to and from our various components.

It should be out “soon.” Nice and vague, yes.
