The newest standard for flash memory cards is SDXC, which supports capacity sizes up to 2 terabytes. This means that you can store 2,000 GB of data on the card.
SDHC cards were first introduced in 2006, and the newer SDXC standard was announced in 2009. The original SD standard supported up to 4GB of storage, with subsequent versions increasing that capacity up to 2TB (or 2,000 GB).
The most popular use for SD cards is for storing digital photographs and video clips on cameras and camcorders. However, many people also use them as portable storage devices for moving files from one computer to another or as a backup device for computers or mobile devices.
