The latest enhancement to Toshiba' extensive line-up of SD Memory Cards are: a 4-gigabyte (GB) Class 6 SDHC Card; a 4GB Class 4 miniSDHC Card; and a 2GB microSD Card. The new SDHC and miniSDHC Cards will be available worldwide from March next year, and the microSD will be launched worldwide next April.

The SD High Capacity standard (version 2.00) takes card-based memory into the broadband era by defining three classes of high speed data write for cards with an enhanced capacity of 4GB and more. The market for these high performance memory cards will grow alongside increasing demand for digital equipment able to handle motion pictures and high resolution images without long delay times. Demand for miniSDHC Cards and microSD Cards will primarily come from mobile phones.

Toshiba's new 4GB Class 6 SDHC meets the ultra high speed Class 6 rating, and delivers a guaranteed sustained write speed of 6MB/s; Toshiba has measured sustained performance at a maximum of 20MB/s. The new 4GB SDHC Card extends the Company's line up of 4GB SDHC beyond the Class 4 card launched in September.

With the new 4GB miniSDHC Card, Toshiba brings to market the industry's first Class 4 miniSDHC Card, capable of sustained write speeds of 4MB/s. This advance will bring new levels of performance and functionality to mobile phones and other personal digital products.

Toshiba rounds out its latest additions with a 2GB microSD Card, reinforcing its overall product line-up in all key areas.
