The Verbatim Premium SDHC 32 GB Memory Card is designed to be used in compatible digital cameras, portable music players, camcorders, smart phones, PC's or other consumer applications. The Verbatim Premium SDXC Memory Card uses 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, the Verbatim Premium SDXC Memory Card guarantees a minimum sustained data transfer speed, not a maximum speed. It is fully compliant with all applicable SD standards and also contains a write protect feature to prevent accidental erasure.
