What is the difference between the SD / microSD memory card and the SDHC / microSDHC memory card?
The SD / microSD memory cards have a capacity of up to 2GB, while the SDHC / microSDHC memory cards have a capacity range starting at 4GB and going up to 32GB. The SDHC / microSDHC memory cards use a different file system and standard than the SD / microSD memory cards. SDHC / microSDHC memory cards cannot be used on SD / microSD memory card compatible devices. Use a SDHC / microSDHC card on a SDHC / microSDHC compatible device. SDHC / microSDHC compatible devices are backward compatible with SD / microSD memory cards as well.
