  Almost certainly fake. Amazon was flooded with cards like these a few years ago. For example, you could get a "1TB" card at a bargain price, less than 10% the cost of a legitimate 1TB card. But the actual capacity would be something like 8GB, and the firmware was hacked to report a larger capacity than actually existed. Steve Gibson has a free program to test for these fraudulent cards: https://www.grc.com/validrive.htm https://www.grc.com/validrive.htm

    There's also 'h2testw', a simple (portable) windows executable, originally from a German magazine. But yeah, there's plenty of fake high-capacity SD and SSD at suspiciously low prices. What gets confusing is that you can also buy mid-performance real 32 or 64 GB SD cards for as cheap as 2 bucks. Perfectly good for occasional cam or tablet use, after testing.
