Toshiba claims the fastest microSD cards in the west -

Toshiba has opened the kimono on what it calls the fastest microSD memory cards in the world.

These microSD memory cards are the first in the industry that comply with the High-Speed UHS-II Interface Standard. This is the ultra-high speed serial bus interface that has been defined in the SD Memory Card Standard Ver. 4.20, and allows users to choose from 32GB and 64GB capacities.

Being UHS Speed Class 3 (U3) enabled, these new Toshiba microSD memory cards will enable high-quality 4K video capture at constant minimum write speeds of 30MB/s.

It will mean that the card can be used to record 4K2K video, live broadcast and content on high-performance cameras.

The 64GB cards have 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. Comparing them with Toshiba's existing 32GB microSD UHS-I cards you would see an 8x write speed improvement and 2.7x read speed improvement.

Sample shipments for chipset vendors and set manufacturers of smart phones and other mobile devices are available now, but no one has mentioned any pricing yet.
