> but consumer QLC drives have now been on the market for five years: the time limit on those drive warranties is now expiring, with no sign of an epidemic of premature drive failures
The failure is not shown as an epidemic, it is shown firstly as a degradation; in forums under questions about why turned so slow the disk that find as answer to enable the RAPID mode (so using RAM cache), in other post as regrets about the purchase, and things like that.
those who know what kind of thing they are buying with QLC store disposable data, at time they do not fill the disk.
Firstly arise the performance problem, if one keeps using it comes the data progressive loss, those are the ones at forums talking about high trim data errors.
" 3D NAND density-increasing techniques, such as extensive stacking of cell layers, can amplify read disturbances and shorten SSD lifetime. From our lifetime-impact characterization on 8 state-of-the-art SSDs, we observe that the 3D TLC/QLC SSDs can be worn-out by low read-only workloads within their warranty period since a huge amount of read disturbance-induced rewrites are performed in the background.

" the SSDs entered an era where one can wear out an SSD by simply reading it. "
