I'm afraid we're misunderstanding each other here. You're talking about the fully-integrated SSD. Not my area of expertise. I'm talking about the endurance of the flash cell transistors. Nobody's claiming significantly higher endurance for the transistors themselves -- what's improved is the stuff on top of them. SSD controllers have gotten better at not trashing any given cell with repeated program / erase cycles. If you measure endurance of modern SSDs versus seven years ago, sure, you'll see better endurance, but that's becasue there's better logic on top, not because the cell transistors are any better than they were.
