What is the SDHC Memory Card?

At the 2006 International CES, the SD Card Association (SDA) announced their establishment of the SD Specification Version 2.0 for the SDHC (Secure Digital High Capacity); making way for the SDHC to be the next generation SD Card.

Engineered to meet higher memory capacities, the SDHC will meet the higher requirements in a new generation technology, enabling SD cards to reach higher capacities - 4GB-32GB.
New electronic devices that will utilize SDHC memory cards include audio/video and telecommunications gadgets such as digital cameras, camcorders, mobile phones, computers, PDAs, plasma televisions, and many more.

 

-    Larger Capacity

Increase in FAT (file allocation table) capacity

FAT32 file system, instead of the FAT16 in regular SD cards

The increased file system for disk allows an increase in volume size limit of files within the memory card to be scattered across the disk

This kind of large capacity is essential for use with a variety of digital content types, and especially with high-quality video.

 

-    Higher Data Transfer Speed

The demand for memory cards with higher data transfer rates have increased due to the need for higher data volumes and the increasing range of digital content.

Transfer Speeds of the SDHC memory cards are categorized in 3 class speeds

Class 2 - 2MB/second

Class 4 - 4MB/second

Class 6 - 6MB/second
