SD card 8GB, fake?

Hi, I bought this card and test it with h2testw_1.4, it give errors, also it is pretty slow, is it fake?

Fake or defective, what does it matter? It needs to be returned to the seller.

Because I want to know that information.

If h2testw_1.4 is only showing a maximum of 2GB memory, then the card is fake. Back when 8GB cards were the largest available, hackers would use the cheaper 2GB cards and make them appear as 8GB ones.

If it shows the card to have 8GB of storage (which it does according to your linked-to image of the test results) then it’s probably just defective. There’s no profitable reason to ‘fake’ an 8 gig card with an 8 gig card.
