So a NVME SSD using TLC could be less expensive, being still very good in long times too (instead of cheper QLC others)

Samsung has not yet made an official investigation, and there are only two possibilities that can be guessed, one is TLC flash memory,The 990 Pro uses Samsung’s 176-layer TLC flash memory (officially called 3bit MLC)It should be a very mature product, and there should be no problems with reliability.
Another possibility is the master control, 990 Pro upgrades Samsung’s self-developed Pascal master. There may be a bug in the algorithm, causing the health to plummet.
For Samsung, starting from the 980 Pro of the previous generation, the flash memory has also been replaced from MLC to TLC, and Samsung’s flagship SSD was originally one of the only benchmarks for MLC hard drives, but due to problems such as cost and production capacity, MLC flash memory has also gone. Never to return, TLC has become the mainstay, and QLC is even more popular.
