Verbatim SDHC Cards are designed to be used in compatible digital cameras, portable music players, camcorders, smart phones, PC's or other consumer applications. SDHC Cards use a FAT32file system, a specification that was established for applications with higher capacity needs and are especially suitable for high-quality video. The increasing use of high-definition video, high-resolution digital photography and mobile applications demands higher storage capacity and more demanding data transfer rates. Because of this, SDHC cards guarantee a minimum sustained data transfer speed, not a maximum speed. Verbatim SDHC Cards are fully compliant with all applicable SD standards. They also contain a write protect feature to prevent accidental erasure.
