Speed Reading with Lexar USB 3.0

New Lexar USB CF and SD card reader

I have a couple of Lexar card readers for transferring video and stills from my Compact Flash cards onto my Mac. It connects via USB which is OK. I'd have preferred a FireWire version - but I couldn't find anyone who made them.

Luckily Lexar has announced it is launching a professional USB 3.0 Dual-Slot Reader that can potentially shift 500MBps. My USB 2.0 version is supposed to clock 60MBps - although in reality it is considerably slower than that thanks to the overhead of the USB protocol, which means that if all the planets are in alignment you might conceivably get up to half the advertised speed.
