microSD cards will soon be available in capacities up to 1 TB (1,000 GB). SanDisk today announced the 1TB SanDisk Extreme UHS-I microSDXC card, which is both twice as fast, and stores more data, than any previous microSD memory card. The same 2x speed technology will also be available in a 512 GB card. The 1 TB card will run $450, while the 512 GB card will be $200. Both cards ship in April, and are available for pre-oder now.
