Toshiba Launches World's Fastest SDHC UHS-I Memory Cards

Toshiba America Electronic Components, Inc. and its parent company Toshiba Corporation today announced the launch of 8GB (gigabyte) 16GB and 32GB SDHC UHS-I cards compliant with the SD Memory Card Standard Ver. 3.0 (SD 3.0), UHS104. These new SD cards offer the world's fastest SDHC data read and write speeds. Toshiba also extended its industry leadership in memory card solutions by unveiling the world's first 4GB, 8GB and 16GB microSDHC UHS-I cards compliant with (SD 3.0), UHS50.

The new SDHC UHS-I Memory Cards are the world's first memory cards compliant with SD 3.0, UHS104. With a maximum read speed of 95MB per second, and a write speed of 80MB per second, the products introduce a new level of ultra-fast read and write speeds to NAND flash based memory cards.

Toshiba's new microSDHC UHS-I cards are the world's first microSDHC memory cards compliant with SD 3.0, UHS50. They, too, offer the world's fastest read and write speeds in their class: a maximum read speed of 40MB per second and a write speed of 20MB per second.

The specifications of the new cards combine increased data capacity with the fast data transfer rates essential for applications such as high speed continuous shooting of high resolution digital still cameras, video, and high speed transfers of HD content. 

The high performance specifications announced by Toshiba will enable developers to use HD content in future generations of consumer products. By further enhancing the performance of its SD Memory Card line-up, Toshiba continues to lead the NAND flash memory market in removable card storage.

The expanded new card series will be featured at IFA 2010, in Berlin, Germany from September 3, and PHOTOKINA 2010, in Koln, Germany from September 21. Mass production of the new SDHC UHS-I cards and sample shipments of the new microSDHC UHS-I cards will start this November.

Outline of New SD Memory Cards

1. SDHC UHS-I Cards

2. microSDHC UHS-I Cards

Key Features

SDHC UHS-I Cards (32GB, 16GB, 8GB)

1. Support UHS104, a new ultra high speed SD interface compliant with the new SD Memory Card Standard Ver. 3.0 (SD 3.0) which supports SD interface bus speeds up to 104MB per sec. enabling the industry's first SDHC card with a maximum read speed of 95MB per second and a write speed of 80MB per second.
2. Provide conventional SD interfaces—3.3V signal voltage for the DS mode (SD clock 25MHz and 12.5MB per sec) and the HS mode (SD clock 50MHz and 25MB per sec)—and are interoperable with existing SDHC host devices compliant with the SD Memory Card Standard Ver. 2.0 (SD 2.0).
3. Integrate highly secure CPRM copy protection technology.

microSDHC UHS-I Cards (16GB, 8GB, 4GB)

1. Support UHS50, a new ultra high speed SD interface compliant with the new SD 3.0 which supports SD interface bus speeds up to 50MB per second enabling the industry's first microSD with a maximum read speed of 40MB per second and a write speed of 20MB per second.
2. Provide conventional SD interfaces—3.3V signal voltage for the DS mode (SD clock 25MHz and 12.5MB per second) and the HS mode (SD clock 50MHz and 25MB per second)—and are interoperable with existing microSDHC host devices compliant with SD 2.0.
3. Compliant with DDR 50 (SD Clock 50MHz) double data rate to achieve a bus transfer rate of 50MB/s compared with the existing HS mode at the same SD clock frequency.
4. Integrate highly secure CPRM copy protection technology.
