If you said that to me I'd call you a liar. What you're saying above is that you guarantee that you can triple the "speed" of his computer, if not more. @OP: I would just explain to him what SSDs are, what are its benefits, then explain to him what RAID0 is, and again it's benefits. Then you let him choose. Make sure to give estimates on how much each costs.
