Recent advancements in NAND flash memory are expected usher in larger capacity solid state drives at more attractive price points. Specifically, the move to 4-bit quad-level cell (QLC) memory is playing a key role here. This could have a trickle down effect on TLC-based drives, as we are seeing with Adata and its new 2TB model that it's adding to its Ultimate SU800 line.

Adata launched its Ultimate SU800 series around two years ago. It uses 3D triple-level cell (TLC) NAND flash memory, paired with a Silicon Motion SM2258G controller. According to TechPowerUp, the new 2TB model (ASU800SS-2TT-C) will use the same combination of hardware.
