Kingston 4GB Secure Digital High Capacity Memory Card - Class 4
Starting at 4 GB, SDHC cards offer larger-volume data storage and optimized recording performance with support for FAT 32 file formats. In addition, Kingston SDHC cards use new speed class ratings known as Class 2, 4 and 6 that deliver a minimum data transfer rate for optimum performance with SDHC devices. Although identical in size to todays standard SD card, the new SDHC cards are designed differently and are only recognized by SDHC host devices.
To ensure compatibility, look for the SDHC logo on cards and host devices (cameras, camcorders, etc.). For added reliability and durability.
