If you're asking if USB 2.0 is faster than 1.1, then definately. USB 2.0 runs at like 500 mbps. USB 1.1 runs at maybe 11? I don't know the exact numbers, but it's crazy good. Now, just using a USB2.0 cable with a USB1.1 hard drive won't make the hard drive any faster. And you'll only get the benefits if you have USB2.0 ports on your computer.
