They aren't any faster, just like most of the "USB 2.0" stuff out there. If the box says "USB 2.0 Full Speed", then that's a case for the Bullsh*it Detector.
USB as of specification 2.0 has three speed levels: Slow, Full, and newly introduced High. Yes, Full speed is less than High speed. Stupid this is, but good for the marketing. "USB 2.0 Full Speed" sounds a lot faster than "USB 1.1", but it's the same thing. You want a "USB 2.0 High Speed" device.
See
www.usb.org for the standardized logos that tell these apart.
