Currently, SDHC specifications allow for memory cards of a capacity between 4GB and 32GB. If the SD card is 4GB or above, it is classed as a SDHC card. SDHC is the same physical size and shape as standard SD but meets the new SD specification of version 2.0. SDHC (Secure Digital High Capacity) was established to meet the growing demand for HD (High Definition) video and high resolution image recording now used in many SD-enabled devices.
SDHC cards are in the following capacities 4GB, 8GB, 16GB and 32GB Currently mainly 2GB SD cards are being sold.Ī SDHC card will not work in a SD device such as a camera or reader. A SD card will normally work in a SDHC device (possibly with lower performance).
