SSD layers: Do you mean each cell is storing around 100 different values or are cells layered on top of each other (each addressed separately etc.)?



The cells are layered but each cell stores 4 bits in QLC.


QLC = "Quad Level Cell", if you're like me and didn't know that.


Which is a strange name and underselling it btw, since there are 16 levels...


16 possible voltage levels, but a given memory cell can only exist in one voltage state at a time. The number of bits per cell is what actually matters, even if the names we assign to those types are dumb.


Sure, I just said that "QLC" basically implies two bits.
