It's really the edge cases that one might run into, where things no longer work well, but I don't recall right now into what problems I've run into (What I did was for the xbox360 devkit to read files from my HDD, rather to copy to it, as was required by the sdk, but I've achieved only 5mb/s, while copying was 10mb/s - the only benefit was if you wanted to read on demand, a bit and for fun).
