A:AnswerHi, please be informed that the SanDisk® microSDXC 400GB Memory Card for Nintendo Switch supports read speeds of upto 100MB/s and write speeds of upto 90MB/s.
A:AnswerAs of right now, the Nintendo Switch does not allow you to transfer game saves to a SD card. You can store your digital games, but the game saves will remain on the internal storage.
A:AnswerYes it will! Any sd card you put into a switch needs to be formatted for that particular switch. So before trying to do any transferring of files etc remember to do that first.
