No, this is the right place to ask.
As one of the closers, my rationale (which I put into a comment that I guess got delete for being "snarky"... sigh ...) was that there was just too much wrong with the question for it to be a good fit for a Q&A site. Basically, any decent answer to that question would have to involve teaching you a book or two's worth of information on RAID and basic... uh, "disk stuff," at which point you'd realize why your idea is just... well awful, to the extent it actually even makes sense.
On top of that, it asks for a subjective opinion, without providing the information needed to get a factually based answer (
what do you think would be the best setup?), which is the definition of a
not constructive question in these parts.
