The HX-WA30 supports a better memory card type than most big sensor size video cameras that have been around for around the same time as it. This video camera supports an SDXC memory card, whereas most big sensor size video cameras that were released more than two years ago support an SDHC memory card. This Panasonic video camera also supports an SD 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).
An SDXC memory card is in fact the best supported memory card type amongst all similar spec camcorders that have been around for around the same time as the HX-WA30.
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.
