The JVC GY-HM200 supports a better memory card type than most camcorders that were released more than a year ago. This video camera supports an SDXC memory card, whereas most video cameras of this age and type support 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 amongst all big sensor size video cameras that have been around for around the same time as the GY-HM200.
An SD memory card is the worst supported memory card type across comparable types of camcorder.
SDHC cards are DS cards with a higher capacity of up to 32GB.
