Question what is the difference of NAND flash when it's labelled as 3D2, 3D3, 3D4 ? is the last number the # of bits per cell?

I think it's bits per cell, but does that relate to density? layers? etc?

Thanks!

No, I did a search to see what it's about. That designation shows for Intel SSDs.

3D2 means second generation 3D stacking. 3D3 means third, etc. Intel SSD 665p is a 3D3 QLC SSD.
