The HDR-PJ810 supports an SDXC memory card which is better than most big sensor size video cameras that have been on the market for a comparable time to it. Most big sensor size video cameras that were released more than two years ago support an SDHC memory card. In addition, this Sony camcorder support MS PRO Duo, MS Pro-HG and MSXC and SD 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 actually the best supported memory card type amongst all video cameras that have been available for more than two years.
An MS Pro-HG 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.
