Toshiba Debuts World's Fastest microSD Memory Cards

First to Comply with the High-Speed UHS-II Interface Standard

IRVINE, Calif., April 16, 2014 — (PRNewswire) — Extending its industry leadership in memory card solutions, Toshiba America Electronic Components, Inc., (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, has introduced the world's fastest[1] microSD memory cards.  The new cards are the first in the industry to comply with the UHS-II[2] interface standard, the ultra high speed serial bus interface defined in the SD Memory Card Standard Ver. 4.20. Available in 32GB[3] and 64GB capacities, Toshiba's new microSD memory cards offer the fastest transfer rates available, are UHS Speed Class 3 (U3) enabled, and allow high-quality 4K video capture at constant minimum write speeds of 30MB/s.  This means that 4K2K video, live broadcast and content can be recorded on high-performance cameras.

The 64GB cards offer a maximum read speed of 260MB/s[4] and a maximum write speed of 240MB/s.  The 32GB cards have a maximum read speed of 145MB/s and maximum write speed of 130MB/s, which represents an 8x write speed improvement and 2.7x read speed improvement when compared to Toshiba's current 32GB microSD UHS-I cards[5].  These faster transfer speeds reduce the time required to download large data movie and music files to smart phones and tablets, and enable camera users to shoot high resolution digital still images in a continuous high speed shooting mode.

Toshiba, the inventor of flash memory, offers a broad selection of memory cards that can be used in a variety of applications including, smart phones, digital still and video cameras, audio players, tablets, and many other portable consumer electronics devices.  The entire memory card line features cryptographic security and high-level copyright protection functions.  Looking to the future, Toshiba will continue to meet market demands by enhancing its line-up of UHS-II compliant microSD memory cards.

Sample shipments for chipset vendors and set manufacturers of smart phones and other mobile devices are available now. For more information on memory products from Toshiba, please visit http://www.toshiba.com/taec/adinfo/technologymoves or http://www.toshiba.com/taec/index.jsp.

Notes:
[1] As of April 16, 2014. Toshiba survey.
[2] UHS-II is the ultra high speed serial bus interface in SD Memory Card Standard Ver4.20 that delivers data at 156MB/s by single lane access and 312MB/s by dual lane access.
[3] Product density is identified based on the density of memory chip(s) within the Product, not the amount of memory capacity available for data storage by the end user. Consumer-usable capacity will be less due to overhead data areas, formatting, bad blocks, and other constraints, and may also vary based on the host device and application. For details, please refer to applicable product specifications.
[4] Maximum data writing/reading speed may vary depending on the host device, read and write conditions, and file size. For purposes of measuring read and write speed in this context, 1 megabyte or MB = 1,000,000 bytes.
[5] microSDHC EXCERIA  MUH-A032G (32GB).
Read Speed: 95MB/s, Write Speed: 30MB/s

*SDHC memory cards (32GB) can be used only in SDXC or SDHC compliant devices integrating the FAT32 file format.
*SDXC memory cards (64GB) can be used only in SDXC compliant devices integrating the exFAT file format.
