NANDs are still produced in 14-15nm afaik. The only reason they got more capacity is 3d stacking but that has an obvious cost wall.

Well, Apple has a pattern of obvious screwups like Butterfly keyboard and obsolescence scams like the whole SSD design.

Unless they stop these anti-consumer policies everything Apple does is Gate worthy.

Your optimism about SSD prices is IMHO unjustified.

NANDs are afaik still produced in 14-15nm so the only way they get more capacity is stacking multiple layers.

So even if they add more and more layers the price of these NANDs will run into a price/capacity wall.
