Dont make ridiculous assumptions, I know full well how raid0 works. I dont really want to get in another argument with you, I dont have the time. But Ill just say this, I have a bit of experience with raid0 arrays and for very specific tasks it does improve performance. In my particular personal experience it was with loading times in BF1942 and for some operations in video editing. That being said, like I said before the overall lack of a gain in day to day people for most people in most situations combined with the dramatic reduction in reliability make it a bad choice.

Peace out.
