Information about SD™ and SDHC™ flash memory cards
The SD™ / SDHC™ memory card is the most widely used type of memory card format designed to meet the converging security, capacity, ergonomic and performance requirements of emerging audio, video, data and multimedia consumer electronics markets. The SD™ Memory Card includes key enhancements over existing Flash cards. These include cryptographic security, protection of copyrighted data, high-data transfer rate for fast copy/download and high storage capacity.

SDHC™ stands for Secure Digital High Capacity, and it is a new standard developed by the SD Card Association to support capacities beyond the 2- gigabyte* (GB) limit of the original "standard" SD™ Cards. Standard SD™ Cards use a file format called FAT16 that supports capacities up to 2GB, while the new SDHC™ cards use a file format called FAT32 that has a maximum capacity of 32GB.

SDHC™ cards also feature minimum speed class ratings. A Class 2 card has a minimum sustained write speed of 2MB/s; Class 4: 4MB/s, and Class 6: 6MB/s.

Attention:
Today's standard SD™ cards can be red by all cameras or other devices equipped with SD™ or SDHC™ card slots (also called SD™ / SDHC™ hosts).

SDHC™ cards are not intended for use in cameras or other equipment with existing SD™ card slots.
