Hopefully something better comes along the way.
Speaking of PLC, isn't it better to decrease cell size and make SLC? Why go to such lengths and store so many voltage levels in one.

thats how its been since day 1.

SLC, MLC, TLC, QLC. You can get larger capacity cheaper the further down you go at a cost of longevity.

its the one thing that wont change.
Actually TLC is today's best solution DWPD wise ...

QLC has 1-2 orders of magnitude less endurance then TLC afaik. Now if QLC drives were 1-2 orders of magnitude cheaper ... but they are not now, or likely to be so, in any reasonable timeframe. QLC is not even a factor of two cheaper then TLC in a lot of client cases.
