Q and A: What are the pros and cons of the super high capacity SDXC memory cards?
Question
I read a blurb on the Internet about the new Class 10 SDXC cards in several brands. This type of memory card sounds perfect: super fast and tons of capacity at 64 gigabytes. Why would anyone want to use any other kind of SD card, except for the high price of the SDXC card? G.R.
Answer
That was certainly interesting news, and the first Extended Capacity cards will be available sometime this spring: Panasonic’s Gold SDXC and SanDisk’s Ultra SDXC. (Other brands, in various speed classes will follow.)
Do note, however, that the Panasonic cards boast a Class 10 speed rating while the SanDisk SDXC cards are Class 4 rated, or not as fast. The SanDisk 64GB card is less expensive however, approximately $350 versus $600 for the Panasonic product.
