That winner of that test, the 840 Pro, uses 2-bit (MLC) cells.

Nowadays, 3-bit (TLC) and 4-bit (QLC) are much more common (not sure QLC even existed back then). So whilst each of these technologies has matured, the drive a consumer may consider today is more likely to be bigger, replacing their HDD entirely, and will probably be capable of fewer writes than an MLC drive from 5 years ago, iiuc.

MLC->TLC transition decreases endurance but 2D->3D transision increases much endurance. Current 3D TLC drives handles more TBWs compared to old consumer 2D MLC drives. So industry going to make QLC chips.

The drives also include more software and more excess capacity to mitigate the problem (except for the cheap ones)
