Each drive may come close to saturating its own channel under unique circumstances (atto,as ssd etc testing is not real world) but that does not mean that raid 0 will show no benefits over a singe drive!!
well lets go over a couple of details. let me know if I error somewhere...

ok, raid 0 serves one purpose and only one purpose. faster speeds, right?

ok.

the maximum bandwidth of sata 3 is 600MB/s, which is theoretical only, since there's always some overhead.

ssd's are already in the mid to upper 500MB/s range.

so you put a pair of them, into a channel of data that maxes out at a theoretical 600MB/s... where exactly is the improvement going to come from?

I mean if it does somehow, then great. But I just don't see it.
