SDHC Cards to be marketed worldwide to meet growing demand for higher capacity storage
IRVINE, Calif., and TOKYO, June 28, 2006 — Toshiba America Electronic Components, Inc., (TAEC)* and its parent, Toshiba Corporation, today announced the company’s first Secure Digital High Capacity (SDHC) memory card. The new 4-gigabyte (GB)1 SDHC memory card is scheduled for availability in September.
The new memory card conforms to the SD memory card ver.2.00 standard introduced by the SD Card Association (SDA) which enables capacities greater than 2-gigabytes to be achieved and features minimum SD Speed Class Ratings to achieve optimal performance for FAT32-enabled hosts. The SD Speed Class Ratings specify a minimum sustained write speed for SDHC cards (Class 2: 2 MB/s2; Class 4: 4 MB/s; Class 6: 6 MB/s).
Toshiba is initially announcing a 4GB SDHC card that exceeds the Class 4 minimum write speed of 4MB/s.
In the future, cards up to 32-gigabytes can be developed that conform to this standard. These higher capacity memory cards are intended for use in applications such as digital video cameras and digital cameras capable of recording video segments and high-resolution pictures, or to provide storage for a larger number of digital photos.
“Our new SDHC cards are an important development in the SD card family to provide higher capacity storage to support video storage applications in camcorders and digital cameras,” said Brian Kumagai, business development manager, NAND Flash, for TAEC.
Note: Because the file format differs, the SDHC memory card is not compatible with standard SD card slots/readers
