SDHC Memory Cards

Faster Storage, More Capacity, Greater Flexibility

The SDHC memory card provides more removable storage power with a capacity range from 4GB to 32GB. The file system is FAT32. Speed Class/UHS Speed Class are available for SDHC cards and host products.

The SDHC card, already a market leader in the digital camera marketplace, preserves photographic integrity and raises the memory performance bar by guaranteeing minimum — more important than maximum — performance rates. This large capacity is essential for use with a variety of digital content types — especially with high-quality video.

In addition, many photo printers, card readers, video cameras and other devices are also equipped for SDHC guaranteed transfer rates, demonstrating the trend toward SDHC memory card leadership.

SDHC-enabled products accommodate SDHC memory cards and are backward compatible with SD memory cards. Data on SDHC cards is protected even if inserted in an incompatible device. SDHC cards also work in standard SD slots with a firmware upgrade.
