These problems with 25 nm make me wonder if EEPROM based drives are doomed. If it's an unavoidable aspect of going to smaller and smaller lithographies, magnetic disks will erase them like an ugly pimple. 3000 writes is already too small, although not tragically so, but if the next generation has only 60% as many, it's essentially unworkable. Even if it has 80%, which is a lot more than 25 nm had compared to 34 nm, it's a huge problem. And the generation after that?
Hopefully this isn't a physical limitation that can't be overcome, but if it is the good old Winchester drive will continue to dominate for the foreseeable future. EEPROMs will probably have a place, because their price will drop even if you can't realistically increase capacities. Maybe they'll be used as cache drives for real hard disks, and then you just throw them out and replace them when they go. If they're cheap enough, it would be pretty useful.
