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)

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.
- metalliqaz 6y agoThe drives also include more software and more excess capacity to mitigate the problem (except for the cheap ones)
- fomine3 6y agoMLC->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.
