What format of SD cards do you use? UHS-II is the second generation of SD cards released in 2013, which offers faster read/write speeds than the first generation. Most camera’s on the market use only UHS-I SD or MicroSD cards. But cameras with long buffer’s and fast continuous shooting speeds usually support these second-generation cards. Knowing which cards your camera uses, will help separate options, as some readers don’t support UHS-II cards. Alternatively, if they do, they only transfer at UHS-I speeds, defeating the whole purpose of buying them altogether.
