There is the matter of out of date, but that's what the forum is for. To ask "what is trim", or "what is a CPU", or "what is the wheel" is not quite forum material. But to ask why a controller can't support trim, or what is the relation between L2 cache and the FSB, or why are supports needed is a better use for a forum. I fear that this goes over most of your heads, as your so caught up on someone's "rude" behavior.
