I buy sdcards from Microcenter which I am sure are chinese cards with "Micro Center" printed on them but
I have never had any problems with them on anything I've used them on and they are a good price.
Same with their 3d printer filament.
Next time I go to the city with the Micro Center in it I am getting a 256Gb card for MiSTer since I am now using
a 128Gb card that was twice as big as needed when I got it that is now running out of space!
At the rate the number of cores are being implemented that might not last as long as the 128Gb card has.
