Amazon is notorious for mixing 3rd party stock with their own in warehouse and ending up with counterfeit SD cards.

Never had had a fake card delivered by Amazon.
I've had it happen twice now. Both times a simple 'product not as described' return/refund was not an issue. But suspect many would not realize they got a fake.

How did you realize you got a fake?

I don't understand all the ratings of these cards and would have assumed U1 was the best, so could you please explain why that's bad? What are we supposed to be looking for if we want high quality?

Depends more on the use case scenario and speed you need. I doubt a Nintendo switch can take advantage of the higher speeds, especially when reading data.

This is brutally slow write speeds. As long as you're using this where that isn't important it seems ok. At 10MB/sec it takes over 14 hours to write 512GB. The most recent microsd card I got (Sandisk Pro Ultimate) is 13x as fast at writing.

There are two checks you need to do. Check the Read/Write speed. And check the capacity you have to fill up the card with unique data the size of the capacity. Then you have to verify the files you just copied. One of the tricks of fakes is to make the full size addressable to same say 1/4 or less of memory. So your OS thinks there's 512 Gb there but there's really only 128 Gb. That same 128 Gb is reused 4 times unknowingly by your OS.

I'm sure there's a utility for that latter one by now.
