SDHC, or Secure Digital High Capacity, is an extension of the SD Card format introduced to overcome the capacity limitations of the standard SD Card. SDHC cards offer higher storage capacities, typically ranging from 4GB to 32GB. This increased capacity allows for the storage of larger files, including high-definition videos and high-resolution photos. While SDHC cards share the same physical size and shape as standard SD Cards, they are not backward compatible with devices designed exclusively for standard SD Cards.
