Well, it seems to perform quite well so far. It kind of leaves the 60F in an odd scenario where I'm not quite sure were it fits in. The 40F has similar specs/performance to the 60F other than port count and the 80F apparently brings in a dual PSU so the 60F is kind of positioned oddly it seems.
I'm not sure what you mean by storage though, only x1 models have storage and I don't believe there is a 41F. At least not yet.
