Panasonic must be mighty annoyed right about now, because Toshiba's seemingly got it trumped
-- when the first batch of lightning-quick UHS-I
cards ship in November, Toshiba's chips will be faster and
larger on day one. As you can no doubt see immediately above, the latter company's fielding full-size SDHC UHS-I cards at up to 32GB that promise maximum read and write times of 95MB/s and 80MB/s respectively, not to mention tiny microSDHC units that still manage a very respectable 40MB/s and 20MB/s. As usual, these numbers are fast and loose, so don't be surprised if you get a good bit less in practice, but you should be able to rely on well above the quoted minimum transfer rate of 10MB/s. No ludicrous early-adopter memory prices quite yet, but we imagine your ego will write the necessary checks as soon Toshiba takes care of that. PR after the break.
Toshiba to Launch the World's Fastest SDHC Memory Card
World's fastest SD card becomes flagship of its SD memory cards line-up
Berlin, Germany, September 2 - Toshiba Corporation (TOKYO: 6502), a leading innovator in NAND flash memory technologies and solutions, today announced the launch of 8 gigabyte (GB), 16GB and 32GB SDHC UHS-I Cards, all compliant with the SD Memory Card Standard Ver. 3.0 (SD 3.0), UHS 104, that deliver the world's fastest data read and write speeds. Toshiba also extended its industry leadership in memory card solutions by unveiling the world's first microSDHC UHS-I Cards delivering 4GB, 8GB and16GB capacities.
Mass production of the new SDHC UHS-I Cards and sample shipments of the new microSDHC UHS-I Cards will start this November.
The new SDHC UHS-I Cards are the world's first memory cards compliant with SD 3.0, UHS104, and introduce a new level of ultra-fast read and write speeds to NAND flash based memory cards: a maximum read speed of 95MB per sec, and a write speed of 80MB per sec.
The new microSDHC UHS-I Cards are the world's first microSDHC memory cards compliant with SD 3.0, UHS50, and they also offer the world's fastest read and write speeds in their class: a maximum read speed of 40MB per sec and a write speed of 20MB per sec.
Image shooting and sharing applications continue to grow in popularity, spurring demand for storage devices and applications that can capture high quality images and videos. The new SD 3.0 specifications meet strong demand in the SD card market and combine increased data capacity with the fast data transfer rates essential for such applications as burst shooting with digital single lens reflex cameras and other advanced digital still cameras, HD digital camcorders, and high speed transfers of data between hardware.
The high level specs and wide range of cards announced by Toshiba will support developers in bringing exciting applications to future generations of consumer products. By further enhancing its SD Memory Card line-ups with products offering larger capacities and higher data transfer speeds, Toshiba will continue to meet market demand, and to lead the NAND flash memory market.
The expanded new card series will be featured at the IFA 2010, in Berlin, Germany from September 3, and PHOTOKINA 2010, in Koln, Germany.
Note:  As of September 2, 2010.
 Maximum read and write speed may vary depending on the host device, read and write conditions, and file size.

1. SDHC UHS-I Cards (32GB, 16GB, 8GB)
(1) Supports UHS104, a new ultra high speed SD interface, and the highest standard in the new SD 3.0, which provides 104MB per sec. bus speed on the SD interface. It realizes a maximum read speed of 95MB per sec and a write speed of 80MB per sec.
(2) Provides the 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 is interoperable with existing SDHC host devices compliant with the SD Memory Card Standard Ver. 2.0 (SD 2.0).
(3) Integrates highly secure CPRM copy protection technology.
2. microSDHC UHS-I Cards (16GB, 8GB, 4GB)
(1) Supports UHS50, a new ultra high speed SD interface compliant with the new SD 3.0, which provides 50MB per sec. bus speed on the SD interface. It realizes a maximum read speed of 40MB per sec and a write speed of 20MB per sec, the fastest speed yet achieved in the microSD industry.
(2) Provides the 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 is interoperable with existing microSDHC host devices compliant with the SD 2.0.
(3) Compliant with DDR 50 (SD Clock 50MHz), with double the bus transfer rate (50MB/s) comparing with the existing HS mode at the same SD clock frequency.
(4) Integrates highly secure CPRM copy protection technology.
