Since I bought my computer from a friend, I have been using the ASRock XFast USB software. It came with the ASRock motherboard (that is, it's not something that was found on the internet and installed because it seems good) and it claims that it makes the USB data transfer faster then without it (ASRock's page about it even claims that the speed can go up to 5 times higher then with motherboards without this app).
My question is: does XFast USB actually improve file transfer (in the appropriate context, that is, a motherboard that is compatible with it such as mine)?
Searching on the web for benchmarks I found "mixed reviews", usually by people who performed not much trustworthy tests. Some people were saying that it does improve, some were saying that it is crap and some others sad it was good for some operations and bad for others (e.g. USB 3.0 versus 2.0). I'ld like to know what is, after all, the actual worthiness of this software and, therefore, if I should use it or not.
