On: Transforming a QLC SSD into an SLC SSD

DIWhy type stuff. Still, fun hack. TLC media has plenty of endurance. We see approximately 1.3-1.4x NAND write amplification in production workloads at ~35% fill rate with decent TRIMing.

TFA reports a maximum write amplification factor of 3.75, which puts you in different ballgame territory altogether.

That's why I mentioned it. They claimed it improved to 1.8 in pSLC mode.

Not surprising given that it doesn't have to "compact" the data into TLC mode and thus rewrite it, if the whole drive is in SLC mode.
