New series of SD memory cards from TAEC and Toshiba

Toshiba America Electronic Components Inc. (TAEC) and Toshiba Corp. are launching two series of SD memory cards that offer high-level data transfer rates and read-write performance. The "high-speed series" will offer a maximum data transfer rate of 5MBps, while the "ultra high-speed series" will push transfer rates to as high as 20MBps, double the rate of any other Toshiba-brand SD Cards. Both series will be rolled out in Japan in October and globally in November.

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 2MBps; Class 4 supports 4MBps; and Class 6 6MBps.

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 512Mbyte, 1Gbyte and 2Gbyte capacities. The SD Speed Class will be clearly stated on the card and its packaging, allowing users to select the card that makers specify for use with their digital products. Applications will include video recording with high performance digital cameras.

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. As a leader in SD Card technology and production, Toshiba decided to promote these moves by leading the industry in launching Speed Class 6 SD Cards, and will now gradually transition its SD Card production to the new cards.

"The speed class is important to maximize performance for demanding applications and help the consumer choose the right card for their camera or camcorder," said Brian Kumagai, business development manager, NAND Flash, for TAEC.

The new SD memory card series will be exhibited at the IFA 2006, which will be held next week in Berlin, Germany. Pricing for the new memory cards was not disclosed.
