Toshiba Corporation is planning to launch two new series of SD Cards offering high speed data transfer rates and read-write performance. The “high-speed series” will offer a maximum data transfer rate of 5 MB (megabytes) a second, while the “ultra high-speed series” will push transfer rates to as high as 20MB per second, double the rate of any other Toshiba-brand SD Cards.
Both series will be rolled soon, initially in Japan in October, and worldwide in November 2006.
In May this year, the SD Card Association introduced the SD Speed Class, defining three minimum data transfer rates for next generation SD Cards: Class 2 supports a minimum data transfer rate of 2MB a second; Class 4 supports 4MB a second; and Class 6 6MB a second.
Toshiba says it is the first in the industry to announce the launch of Class 6 products.
Both the high-speed series Speed Class 4 SD Cards and ultra high-speed series Speed Class 6 SD Cards will be made available in 512MB, 1GB and 2GB capacities.
Toshiba expects Speed Class to become an integral part of SD card specifications, and to prove popular with users by indicating which Speed Class SD Card is best matched with which product. Classifying standards for transfer rates will also assure that SD Card continues to evolve to meet new market demands, such as high speed capacity storage in support of digital video.
