Before Using your SDXC Memory Card

The first SDXC memory cards and SDXC host products (digital cameras, video cameras, mobile phones, etc.) have begun to reach the consumer market. As an early adopter of the new SDXC technology, it is important that you understand how to use your new SDXC memory card to its greatest capacity.

Confirm Compatibility

Before inserting your SDXC memory card, confirm the host product is SDXC compatible by locating an SDXC logo on the host product or referring to the host product's instruction manual or manufacturer's information.

Understanding Backwards Compatibility

SDXC Backwards Compatibility Configuration

SDXC memory cards can be used only with SDXC host products.

SDXC host products can use SD, SDHC and SDXC memory cards.

SDHC memory cards can be used with SDHC and SDXC host products.

SDHC host products can use both SD and SDHC memory cards.

Backwards capability is a standard, for example a data format in electronics such as video cameras and computers. A device is backwards compatible if products designed for the new standard can receive, read, view or play older standards and formats.

Only Use SDXC Memory Cards in SDXC Host Products

SDXC host products are backwards compatible with earlier SD and SDHC memory cards. SDXC memory cards should not be used in non-compatible host products.
If an SDXC memory card is inserted into a PC or a host product that does not support SDXC memory cards, a message may prompt you to format the card. Do not format the SDXC memory card in a non-compatible host product; it will erase the data on the SDXC memory card and format the card for a different file system that will no longer work with SDXC host products.
