Just posting in reply to a previous comment, here are the everdrives I have and the sd cards working in them.
Do you have some context? Is it about some SD cards not working or something? Because I use a SNES Everdrive and had random no name cards in them I fished from the bottom of my junk drawer. Have never had any issues at all, seems like if it's a functional card, the Everdrive likes it just fine.
It seems kind of a shame to use high performance cards in them, as the hardware can't use any of that at all.
