WikiAnswers - What is the biggest SD card

WikiAnswers - What is the biggest SD card: "Strictly speaking SD cards are upto 2GB capacity. To support ever increasing demand for memory capacity a new standard SDHC (Secure Digital High Capacity, SD 2.0) was introduced which enabled capacities above 2GB. These cards are called SDHC and are available upto 32GB capacity. But SDHC cards are not compatible with older devices which support only SD card standard devices. Devices which support SDHC due to backward compatibility support smaller capacity (less than 2GB) SD cards also. In summary SDHC cards only work in SDHC compatible devices, but standard SD cards work in both SD and SDHC devices."
