Thanks for the fast replies :)

But NVRAM once made a conceptual sense in the SSA 100 series. Why not
in the A5000? (power failures etc). I understand that the optical
medium is going from host to disk directly. But how are asynchronous
I/O (fastwrites it was called in the SSA 100) etc handled in the A5000?

Sorry for being ignorant. It's not mentioned anywhere in the
documents so it must be pretty clear but I don't get the point.
