Secure Digital Memory Card

Kingston offers a wide range of Secure Digital Cards / SD Cards.

Introduced in late 2001, Secure Digital is a second-generation derivative of the MMC Cards standard (MultiMediaCard). The SD format includes several important technological advancements, such as the addition of cryptographic security protection for copyrighted data/music. Secure Digital cards are a bit thicker than the original MMC cards. However, devices exclusively designed for MMC cards will not support the thicker SD cards at this time.

Kingston Secure Digital Memory Cards

Kingston offers standard SD cards as well as high-performance Elite Pro and Ultimate SD cards.

Kingston Secure Digital High Capacity Memory Cards

Secure Digital High Capacity (SDHC), starting at 4GB, offers larger volume data storage and optimized recording performance with support for FAT 32 file formats. In addition, Kingston’s 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 today’s 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.).
