Sure, but what real world application is benefiting from this? The discussion appears to be centered around running the OS on a raid 0, so even with near-zero access time, what is the benefit?
That's the whole thing, right now we're not sure.
RAID-0 with mechanical drives was very much useless (except in very specific scenarios) because the main limiting factor for speed was their access time, which didn't change, now matter how many drives your used. With SSDs, that bottleneck is removed, so we may
see good improvements with RAID-0. The thing is, I haven't yet come across any comprehensive reviews to swing this one way or the other. However, I'm open to the possibility.
