> Your comment, along with other users, suggests that TLC is a positive attribute for consumers, however, the transition from SLC and MLC NAND to TLC and QLC 3D-NAND actually marked a decline in the longevity of SSDs.

The bit that you're pointedly ignoring and that none of your quotes address is the fact that SLC SSDs had far more longevity than anyone really needed. Sacrificing longevity to get higher capacity for the same price was the right tradeoff for consumers and almost all server use cases.

The fact that 3D NAND has some new mechanisms for data to be corrupted is pointless trivia on its own, bordering on fearmongering the way you're presenting it. The real impact these issues have on overall drive lifetime, compared to realistic estimates of how much lifespan people actually need from their drives, is not at all alarming.

Not using SLC is not insane. Insisting on using SLC everywhere is what's insane.
