XQD

As of right now, the XQD market is pretty thin on the ground. Only one camera uses the high speed cards (the Nikon D4), and only one manufacturer produced them (Sony). Luckily, Lexar has now come on board, and announced support for the still fledgling format. Lexar expects to have these cards available for sale in Q3 of this year.

Earlier this month, Sony released the first XQD format memory card, but the company isn't stopping there with pushing into new storage options. Sony has now announced that they're creating a new line of high-speed SD cards. The flagship UHS-I series will be available in 8GB, 16GB, and 32GB versions, and promises 94MB/s read and 45MB/s write speeds. Starting at $44.99 a pop, Sony has also treated them to be water resistant, and will have them on shelves in March.
