This USB sick was sold by a large company (Mediamarkt). I don’t think they do sell counterfeit sticks.
I was not able to copy a 4.7Gb file on the stick in its original exFAT file system. Reformatted it to exFAT in Windows.
Then I was able to copy a 4.7Gb file on the stick. Still I believe there is a difference in the file system.
I wonder if someone is able to reproduce this with a new usb stick.
