What is the difference between a microSD and microSDHC card?
A. microSDHC memory is a high capacity version (8GB and above) of the microSD format. A microSDHC memory card has the same physical characteristics as a regular microSD card, so a microSDHC card will always fit into a microSD memory card slot. However, it’s important to note that some microSDHC cards won’t be compatible with older devices due to the difference in format.
