Kingston Technology’s Secure Digital High Capacity (SDHC) memory cards are fully compliant with the latest SD Association specification. They are a performance class of SD memory cards designed to meet the storage demands of high-quality digital still and video cameras and other personal electronic devices. Starting at 8GB, SDHC cards offer larger-volume data storage and optimized recording performance with support for FAT 32 file formats. In addition, Kingston’s SDHC cards use speed “class” ratings known as Class 4 that deliver a minimum data transfer rate of 4MB/s for optimum performance with SDHC devices. Although identical in size to standard SD cards, the SDHC cards are designed differently and are only recognized by SDHC & SDXC host devices. To ensure compatibility, look for the SDHC logo on cards and host devices (cameras, camcorders, etc.). For added reliability and durability, our solid-state SDHC memory cards are built of nonvolatile memory components and have no moving parts that could wear out or break. All cards are 100-percent tested and are backed by a lifetime warranty.
