I can only speak from my own experience, but there are a number of low to mid grade SSDs that use truly awful flash and/or controllers. I've bought many of them over the years for unimportant workloads, and have been unpleasantly surprised by how quickly I can burn them out. It's really worth it to shell out for higher end models just for the increase in durability.

Out of curiosity which brands?

All but the highest models of SanDisk have done this to me, as well as the lowest end of Western Digital, ADATA, Kingston. Same for some lesser brands that I've forgotten (not fakes, just shoddy).

Yeah, I'm not doubting that, and this is consistent with my own experience. But the claim was that it was specific to NVMe SSDs, which I find very odd.
