Kingston’s Secure Digital High-Capacity (SDHC) Memory Cards 8 GB
By VARINDIA - 2010-03-25
Kingston’s Secure Digital High-Capacity (SDHC) 8 GB memory cards are fully compliant with the new Secure Digital Association 2.00 specification. This is a new performance class of SD memory cards designed to meet the storage demands of high-quality digital still and video cameras and other high-resolution image recording devices.
SDHC cards offer larger-volume data storage and optimized recording performance with support for FAT 32 file formats. In addition, Kingston’s SDHC cards use new speed “class” ratings known as Class 2, 4 and 6 that deliver a minimum data transfer rate for optimum performance with SDHC devices.
Even though identical in size to today’s standard SD card, the new SDHC cards are designed differently and are only recognized by SDHC host devices.
SDHC (Secure Digital High-Capacity) is a new Flash memory card based on the SDA (Secure Digital Association) 2.00 specifications. SDHC provides removable memory storage for compatible digital devices, including cameras, camcorders, PDAs, MP3 players and more.
The increasing use of high-definition video and high-resolution digital photography demands higher storage capacity and more demanding data transfer rates. Because of this, the new SDHC cards guarantee a minimum sustained data transfer speed, not a maximum speed.
The previous versions of SDA specifications did not provide such common standards for sustained data transfer speeds to be shared by all manufacturers. The new speed classification approach allows users to select card performance based on the needs of particular applications, such as HD video and other MPEG applications, rather than just a maximum speed rating.
SDHC cards use the same physical format as SD cards, but cannot be used with SD host devices that do not comply with SDA Specifications Version 2.00.
