The Vixia HF R400 supports a better memory card type than most video cameras of a comparable spec and age to it. This Canon video camera supports an SDXC memory card, whereas most video cameras that were released more than two years ago support an SD memory card. This video camera also supports an SDHC memory card. SDXC cards are SD cards but with a much higher capacity and faster processing speeds. They have a maximum capacity of 2TB (Terabytes).
This camcorder's memory card type (SDXC) is actually the best supported memory card type across all small sensor size camcorders that have been available for around the same time as the Vixia HF R400.
A MicroSD (Transflash) memory card is the worst supported memory card type amongst comparable types of camcorder.
SDHC cards are DS cards with a higher capacity of up to 32GB.
