Toshiba America Electronic Components, Inc. has introduced the world's fastest microSD memory cards.

The new cards are the first in the industry to comply with the UHS-II interface standard, which is the ultra high speed serial bus interface defined in the SD Memory Card Standard Ver. 4.20. They are available in 32GB and 64GB capacities and offer the fastest transfer rates available.

The new microSD memory cards 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 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. This is an 8x write speed improvement and 2.7x read speed improvement when compared to Toshiba's current 32GB microSD UHS-I cards. 

These faster transfer speeds reduce the time required to download large data movie and music files to smart phones and tablets. It also enables camera users to shoot high resolution digital still images in a continuous high speed shooting mode

Toshiba said sample shipments for set manufacturers of smartphones and other mobile devices, and for chipset vendors, started April 16.

In recent years, with the development of high-function smartphones and tablets, the trend is towards higher resolution photos and movies, and multi-function applications, leading to demand for larger external memory and faster transfer speeds. Looking to the future, Toshiba will continue to meet market demands by enhancing its line-up of UHS-II compliant microSD memory cards.

Toshiba said the new microSD memory cards can be used in a variety of applications including, smart phones, digital still and video cameras, audio players, tablets.  The entire memory card line features cryptographic security and high-level copyright protection functions.
