I formatted my SD card inside my N3DS as fat32. I formatted my SD card inside my GW as xfat. Both are identical 64GB Micro SD Cards. Kingston brand bought from a reputable source. While transferring files from my PC to the cards: The one formatted as xfat is getting like 12mb/s transfer speed. the one formatted as fat32 is getting around 1mb/s transfer speed. Is that formal? Would being formatted as fat32 be why it's so slow?
