Toshiba shows off 'world's fastest' microSD cards

Toshiba has just unveiled the world's fastest microSD cards, cards that the company claims can handle 4K video.

Available initially in 32GB and 64GB versions, the cards are rated at UHS Speed Class 3 (U3) and they are the first to use the new UHS-II interface standard.

Notes Toshiba: UHS-II with U3 means support for "high-quality 4K video capture at constant minimum write speed of 30MB/S. This means that 4K2K video, live broadcast, and content can be recorded on high-performance cameras."

The new announcement is of great significance to the industry, given that product makers will no longer have to sacrifice valuable space to accommodate bigger cards, like full sized SD.

Toshiba claims the 64GB card has a max read speed of 260MB per second and write speed of 240MB/s while the 32GB has 145MB/s and 130MB/s, respectively. Compared to previous cards, the new specs "represents an 8x write speed improvement and 2.7x read speed improvement when compared to Toshiba's current 32GB MicroSD UHS-1 card."

There was no word on commercial availability or pricing.

We're so far away from standardizing the implementation of 4K to every household that by the time we do get to that point.............these lame ass cards will be done better 10 times over.

Waste! Besides, 4K is not worth the jump from 1080 for most people as the difference is NOT night and day. It's subtle to say the least but rather negligible.

At the very least, the difference is NOTHING even close to the transition from SD to HD.

I don't know much about 4K because I have no need for it so I have not done any research on it but if a blu ray is 25-50 gig won't a 4K movie be larger in size?? Will 32 or 64 gig be enough?? If someone could explain it to me.

I feel 4k is more for bragging rights than actual quality. My 22" 1080p monitor has higher ppi resolution than a 52 " 4k tv. This is akin to the stereo amplifier makers talk in terms of frequency range of 20Hz 20 20,000 Hz. What is the actual range that a human can hear? In ld time photography there was something called "circle of confusion" related to perceived depth of field. This deals with limitations of human sight. Similarly file size does not really matter. I have watched 1.5 mbps ripped BluRay movies of 42" 1080P TVs. These amount to something like 1gb / hour. At 4 k resolution they might expand to 4 gb /hour. My $ 100/- media player can stream a 1080p, 14 mbps 5.1 video from a standard HDHC card without a glitch. Why won't the card feed a 4K video ?
