Although I have other high capacity memory cards available for my digital camcorder, I rarely find myself needing to use anything outside of this Sony 64GB SF-64UY SDXC UHS-I memory card. Especially for those who do not remove pictures and video from their portable media very often, the extended capacity of this memory card is ideal and has proven to be quite dependable.
