The single SD card slot on the Sony a6300 mirrorless camera is compatible with UHS-I SD cards. If you wish to shoot 4K video with the Sony a6300, you must use a fast UHS-II SD memory card; otherwise, you’ll have to wait longer for the buffer to empty before you can take another photo.

Therefore, purchasing a fast card is always worthwhile: Fast write speed enables rapid buffer clearing between burst shots, hence enhancing the shooting experience.
