[citation][nom]PortDependant[/nom]@mscheele to be able to fully harness the full potential of a UHS-1 (and now 2) card you would need a device that has the hardware to handle the speed, currently there are only a handful of devices that will support UHS speeds, the nexus one is not one of these devices, plonking a USB 3.0 device into a USB 2.0 port aint going get you USB 3.0 speeds[/citation]
Haha funny you should say that. In terms of USB flash drives, no USB flash drive is 'high speed' 10Mb/s is a max. With a USB 3 flash drive you get the full speed of USB 2.0. So yes you can get a benefit from the card. (This is from personal experience, testing flash drives for the office). Will it be worth buying if you dont have a compatible device, probably not, but the card itself can handle as much as the connection can throw at it.
