SD standards are available in three capacities: SD standard, SDHC standard and SDXC standard. Each of these formats has a variety of speed options, giving product developers the flexibility they need to create products for a variety of needs. The standards have the broad interoperability and compatibility needed to ensure support between multiple devices and for future applications.
SDXC Memory Cards: Massive Storage
The SDXC memory card standard dramatically improves consumers' digital lifestyles and provides more upgradability choices by increasing storage capacity from above 32 GB up to 2 TB. SDXC standards will allow your electronic devices – from tablets to cameras, camcorders, TVs, HDD recorders/players, PNDs and mobile phones – to store and download more content than ever before. An SDXC memory card enabled with UHS will be able to move that data faster than ever before.
