SDHC is the new designation for any microSD or SD-based card that is larger than 2GB and adheres to the new SD 2.00 specification that is required for cards and hosts to support 4GB to 32GB capacities. The specification was developed by the SD Association, an industry standards board, which also defined three speed classes for speed and performance capabilities. These cards adhere to the SD Speed Class 2 Rating specification which defines a minimum sustained transfer speed for SDHC cards.(3)
