Toshiba Corporation today announced that it will launch a new series of SD memory cards offering the world's fastest data write speed. The latest edition to its line-up of EXCERIA memory cards designed to offer users of high-end digital cameras an excellent experience, the EXCERIA PRO and EXCERIA cards will be launched in major markets worldwide, starting with Japan in October.

EXCERIA cards compliant with UHS-II will be available in two series. The EXCERIA PRO series will offer photographers a data write speed of 240 MB/sec the world's fastest, while the EXCERIA series will write at 120 MB/sec. They will allow digital camera users to shoot still images continuously at high speed.

The cards are the first in the EXCERIA line-up to integrate a newly developed controller compliant with UHS-II the ultra high speed serial bus interface defined in SD Memory Card Standard Ver. 4.10, and they achieve significantly higher data transfer speeds than earlier UHS-I compliant cards.

While digital cameras have made huge strides in image quality and versatility, users have long wanted to see improvements in data transfer rates and write times, so as to be able to takes bursts of photographs in quick succession. This demand has grown increasingly strong as high performance digital single-lens reflex cameras and mirrorless interchangeable-lens cameras have gained popularity and moved into the mainstream. Further advances in higher resolution image recording (including 4K2K video), will also fuel demand for transfers of data-rich images at high speed.

Looking to the future, Toshiba, a world leader in the NAND flash memory business, will continue to meet market demands by enhancing its line-up of UHS-II compliant SD memory cards.

Outline of New SD Memory Cards

Key Features (All EXCERIA series)

1. Compliant with the SD Memory Card Standard Ver.4.10 HD312, which defines 312 MB per sec as the fastest data transfer speed under the SD Memory Card Standard Ver.4.10 UHS-II.
2. SDHC memory cards (32 GB, 16 GB) are interoperable with SDHC host devices compliant with SD Memory Card Standard Ver.2.0.
3. Integrates highly secure CPRM copy protection technology.
4. The minimum recording speed is UHS speed class.
