Toshiba Intros World's Fastest MicroSD Card

Toshiba America Components revealed the "world's fastest" microSD memory cards. These cards are the first to comply with the UHS-II interface standard, the ultra-high speed serial bus interface defined in the SD Memory Card Standard Ver. 4.20.

"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," states the PR. "This means that 4K2K video, live broadcast and content can be recorded on high-performance cameras."

According to Toshiba, the new microSD card comes in 32 GB and 64 GB capacities. The 64 GB model (THNSX064GBK5M4) boasts a maximum read speed of 145 MB/s and a maximum write speed of 130 MB/s. This transfer speed reduces the time required to download large data movie and music files to smart phones and tablets.

The 32 GB model (THNSX032GAJCM4) is a bit zippier in read/write speeds, providing a maximum read speed of 260 MB/s and maximum write speed of 240 MB/s. That's an 8x write speed improvement and 2.7x read speed improvement compared to the current 32 GB microSD UHS-I cards.

"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," states the PR.

Sample shipments for chipset vendors and set manufacturers of smart phones and other mobile devices are available now. Currently, there is no information about when these cards will be implemented into hardware nor when they're available to the public.

    must be tons of little nand dies inside (instead of 1 big die) to reach those write/read speeds

    So all they are giving us is the maximum speeds and expect us to buy this crap?
    This is the Kingston SSD bait and switch all over again.
