Product Information :  SanDisk Extreme III SDHC Class10 32GB

There are several types of memorycards, the most usual are CompactFlash, SmartMedia and MultiMediaCard. Most of the products that use digital media is made for one of these types.

There are two kinds of Speed Class, "Speed Class" and "UHS Speed Class."As a characteristic of flash memory, actual transfer speed varies. Variable speeds are difficult to reliably record streaming content such as video because it requires a constant writing speed. Speed Class and UHS Speed Class provide the constant speed necessary for video recording by designating a minimum writing performance so that minimum and constant speed is guaranteed for camcorders, video recorders and other devices with video recording capabilities under the conditional write operation specified in the standard.Speed Class, designated as Class 2, 4, 6 and 10, is designed for normal and high speed bus interface (mode) and UHS Speed Class 1 is designed for UHS bus interface*. (Speed Class and the UHS Speed Class are not compatible.)
