What is SDHC?

SDHC is the new generation SD card built upon the new SDA 2.00 specification, which allows SD cards to reach capacities of 4GB up to 32GB. The new specification is released in response to growing demand for high quality photo images and high resolution video recording capabilities which requires large amount of storage capacity.

What is Class Speed Rating?

The SDA defines 3 speed classes in order to let users identify speed and performance capabilities of SDHC cards and the host products. The speed class rating specifies a minimum sustained write speed for SDHC cards.

Class 2: 2MB/sec
Class 4: 4MB/sec
Class 6: 6MB/sec

Compatibility

Note: SDHC cards are not backwards compatible with standard SD host devices. Standard SD cards are forward compatible with SDHC host devices. To ensure compatibility, look for the SDHC logo on the host device packaging. Please check with your device manufacturer for their current/future supported SDHC devices.
