The data has to be stripped off the source drive and written to the target drive - depending on what kind of drives you have and how much memory (buffer) space is available, nobody gets anything like the theoretical max.

Still, it's a lot faster than my 100 mbps network, but in reality that only shows up when I'm transferring large files around; with small stuff, it's not all that noticeable.

All in all, for five bucks it seemed to be worth it to have the capability (literally) in my pocket and easily transportable.
