The HDR-CX200 supports an SDXC memory card which is better than the SD memory card supported by most comparable spec camcorders that were launched more than two years ago. This video camera also support Memory Stick (MS), MS PRO Duo and MS Pro-HG Duo and SDHC memory cards. SDXC cards are SD cards but with a much higher capacity and faster processing speeds. They have a maximum capacity of 2TB (Terabytes).
An SDXC memory card is in fact the best supported memory card type across all medium sensor size video cameras that have been around for a similar time to the HDR-CX200.
A MicroSDXC memory card is the worst supported memory card type across similar types of camcorder.
SDHC cards are DS cards with a higher capacity of up to 32GB.
