  1. Does it seem like SSD progress is beginning to level off? Most current SSDs remain MLC planar, at around 16-20nm in size. There's a few value-oriented TLC SSDs as well. But at some point, it is looking like the die shrinks are going to start levelling off. Perhaps maybe ~10nm is the end? Does it seem like 3D NAND too is no easy solution over planar? It does seem like Samsung in particular is stuck at 40nm for now with 3D NAND for at least the next couple of generations, and I'd imagine the other vendors would encounter similar technical difficulties. It may very well be that the benefits were somewhat overhyped. It's not clear I think whether it will scale down very well past 40nm either. Performance-wise, I think we are seeing NVMe drives start to enter the market. Whether that will impact much save the high end though remains open to debate. So is that it, are we seeing SSD performance level off then? Likewise, is the rate of price drop going to level off as well in terms of rate of cost declines in cost:gb?
