SDHC are the latest generation of SD cards based on the SDA 2.00 specification, allowing SD Cards to reach capacities of 4GB up to 32GB. The new specification also defines 3 speed classes to determine performance capabilities of SDHC cards and host products. The speed class rating specifies a minimum sustained write speed for SDHC cards. SD Cards include a proprietary cryptographic security scheme for copyright enforcement, which entities with DRM interests consider a 'feature.' ATP cards come with a 5 year limited warranty.
