SSD / Flash becomes more fragile with node shrinks, so flash (currently) kind of has hit the limit on shrinking, and they do "layering" to get more storage/density. Not sure how much they can keep pushing layering, I think they are already at 96 layers at consumer and are having problems above 128, but I haven't checked the state of ssd in 6 months. I suppose the investment cost will age out and ssd multilayer will continue to drop, but flash supply (and HDD supply) is effectively a cartel these days of not-that-many players/competitors.
