Is it better to play memory cards at Polaroid at high speed or extremely fast?

Nice speed. High-speed memory card can shoot high-definition video, and the shot video is smooth and has good image quality. Fast memory cards can have higher definition and better picture quality, so they are extremely fast. However, when choosing a memory card for photographic equipment, the sooner the better, but according to the actual needs and the speed limit of the equipment. Compatibility of different devices of memory cards should be considered. Old equipment has restrictions on the speed of accessing the Internet with memory cards, and even if you buy a high-speed card, it can't fully function.
