Toshiba launches world's fastest microSD memory cards

3 Comments

Toshiba Corp has launched the world’s fastest microSD memory cards, compliant with UHS-II, the ultra high speed serial bus interface defined in SD Memory Card Standard Ver. 4.20. Sample shipments for set manufacturers of smartphones and other mobile devices, and for chipset vendors, began on Friday.

The new microSD memory cards will be available in 32GB and 64GB capacities. The maximum read speed of 260 MB per second and the maximum write speed of 240MB per second in the 32 GB cards and the maximum read speed of 145MB per second and the maximum write speed of 130MB per second in the 64 GB cards, are all the fastest transfer rates in the industry.

Compared to Toshiba’s current 32GB microSD UHS-I cards, the write speed is improved approximately 8 times, while the read speed is improved approximately 2.7 times. The faster transfer speeds can contribute to shortening the time it takes to download large data movie and music files to smartphones and tablets. It will also allow camera users to shoot digital still images continuously at high speed.

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.

What might the "class" number for these be?. When I got my smartphone last year, I installed a "class 10" SD card that was the fastest available at Yodobashi Camera at that time. How will these compare?

I believe that it will be class uhs-II and we will be able to record high quality 4K

Currently one can get a class 10 UHS-I compatible card with speeds averaging 40 mb/s, this is different from a simple Class 10 card which has a much lower read/write speed. In any case one's intended device has to be capable of utilizing that option. Got one micro-sd yesterday with 32gb capacity for 2050yen in the backstreets of Akihabara.
