@freemo The memory controller is usually the garbage that fails so it's rational to think that some random micro SD card will work about as well as a trusted brand. These embedded memory controllers suck and are the main reason why SSDs and USB drives fail.
You could be getting a bined 2tb card that only works with half the memory. The sketchier it seems, the more likely that is legit. Some weird coating and weird ID is probably removing the original manufacturer and allowing for such a product.
Intel was notorious for taking rejected chips and marketing them as lower spec Intel processors. Essentially everything electronic is mediocre and lies but manufacturing is expensive.
