SD card speed is determined by its class. The higher the class, the faster the SD card can transfer data. Classes 2, 4, and 6 are suitable for standard-definition video recording, while classes 10, UHS-1, and 3 are needed for high-definition video recording. The capacity of an SD card is usually described in terms of gigabytes (GB). The largest SD cards currently available have a capacity of 128GB. When purchasing an SD card, it’s important to make sure that it’s compatible with your devices. Some devices are not compatible with SD cards larger than 32GB, while others may require a specific type of SD card in order.
