What is SDHC?
To support the higher capacity needs, SD cards are now requiring a different design. The new SD 2.0 specifications - which supports 4GB and up - is called Secure Digital High Capacity(SDHC). The SD Association has created and defined 3 speed classes to help you identify speed and performance capabilities/minimum requirements of SDHC cards and their SDHC host products.

The 4GB mini SDHC is class 4 and 6 created and defined by the SD Association to help consumers identify speed and performance capabilities/minimum requirements of mniSDHC cards and the host device. Class is dependent on the write-speed of the card, the higher the ¡°Class¡±, the faster the memory card.
