Another technology that will see its latest revision usher in dramatic increases in capacity is SD cards. The latest incarnation is called SDXC (Secure Digital eXtended Capacity) and has a maximum size of 2TB. Just imagine 2048GB in a card small enough to swallow.
What you need to know about SDXC
Don’t expect 2TB cards to appear just yet. 48 and 64GB cards from Panasonic and Toshiba should start appearing this Spring, with other vendors to follow closely.
You should also have some restraint; don’t rush out to buy SDXC cards without having devices that can read them. SDHC devices can read a small subset of SDXC cards only, and not at full speed.
The other major point that you should keep in mind is that only Windows 7 currently supports reading SDXC.
You can get more detailed information from the SD Card Association.
