Digistor has come to the conclusion that I suspected, that this is an issue with TLC NAND.

What does this all boil down to?
Simply that TLC NAND is not the future of data storage, and it doesn’t even have a good seating in the present. If your data matters in the long term, you’ll want to go with a higher-quality NAND: MLC-NAND for your basic SSD needs, or SLC-NAND for industrial use or super-sensitive data storage. There’s no other way about it.
