ASUS Motherboards First to Implement USB-attached SCSI to Boost USB 3.0 Performance

With its latest P8Z77, ROG Maximus V, and Sabertooth Z77 motherboard lines, ASUS became the first PC motherboard vendor to implement UASP - USB-attached SCSI Protocol. UASP changes the way the computer and connected USB devices talk to each other. It ensures more efficient utilization of bus bandwidth (5 Gb/s), resulting in higher bandwidth yield to connected devices. UASP allows connected devices to exchange multiple commands at once, reducing protocol overhead. UASP is implemented on ASUS motherboards using third-party controllers that support it. So far we know the likes of VLI to have such host controllers. In addition to these, ASUS motherboards also provide USB 3.0 ports wired to Intel PCH chipsets.

What a load of hog wash.
This is NOT news and NOT a new features.
UASP is going to work with all USB 3.0 host controllers come Windows 8.
Right now it's down to licensing a UASP driver from either Renesas or one other company I've forgotten the name of if you want it to work in Windows 7.
Gigabyte announced UASP support a year and a half ago, so it's hardly a unique feature. ASMedia and Renesas are afaik the only two companies that are providing it with their drivers for Windows 7 due to the extra cost, VLI does not as far as I'm aware as they're not willing to pay for the licensing.

Interesting, consumer lvl USB raids perhaps now a possibility ?
