Toshiba is upping the ante in the microSD card department, launching new high-end cards that they're calling the "world's fastest". Using the new UHS-II SD card specification, these microSD cards are designed for 4K video recording, giving cameras too small...

People really have to appreciate this endeavour. Toshiba was able to create an ultra fast storage device the size of the tip of your finger... You basically have the capacity of an old 3.5 inch HDD (64GB) from a few years back in an ultra small factor. Truly amazing. I can never wrap my head around how they did it.

Lol, afaik, my local favorite gadgets store in the Philippines which sells cheap electronic products made in china (and imported by the store), has yet to carry class 10 microsd hc cards. most microsd cards are still class 4.
I didn't even know the existence of uhs-II and its 'older sibling' uhs-I before reading this article by tim schiesser.
I'm so still in stone age, figuratively. :)

Thats impressive at that size and form factor. I mean thats Gen II SSD speeds on something so tiny which is very cool for photos, phones, and raspberry Pi's or the likes.

Naturally it'll be very expensive initially but prices will drop significantly eventually and that's when I'll hop on the bandwagon.

CD-R King ? hehe. UHS-I is here for a long time but it is just too expensive and people doesn't seem to care what Class of the microsd card they've buying. they only care about the capacity :) Even CD-R King sells UHS-I(Sort Of).

guilty as charged. :)
every tech gadget/accessory I like costing less than 2000php I buy at cdrking, usually less than three months warranty. attention: DTI Philippines.
other 'more expensive' things I buy at regular store for the more complete warranty option (usually one year).

I'm missing something here:
These new microSD cards are rated for UHS Speed Class 3, indicating minimum write speeds of 30 MB/s, which makes the small form factor storage suitable for sustained 4K video capture for the first time. The UHS-II specification supports theoretical maximum transfer rates of 312 MB/s, so Toshiba isn't reaching the speed barrier just yet.

But before that:
The cards will be available in 32 GB and 64 GB capacities, the former packing maximum transfer rates of 260 MB/s during read and 240 MB/s during write, and the latter with 145 MB/s read speeds and 130 MB/s write speeds. Toshiba claims the 32 GB model is eight times faster than the company's existing 32 GB UHS-I microSD card, which is a pretty significant improvement.

Is the former spec, (class 3), when the card is used with a standard microSD slot? Because 145MBs, is clearly class 10+.

What is the point of designing these in microSD anyway? Does anyone really think the optics in a device as small as the future, "iPhone 7 4K", will be able to do justice to HD at that resolution.

IMHO, standard SD is small enough to easily lose anyway, so what's the point?

Class 4 is standard today, the other Class 6, 8, 10, and up just really don't seen the difference. Before the Class ID Tag it was X150 speed. There are a lot of Class 2 out there for Mobile MicroSDC or SDC. The Reader/Writer would have to up to speed too or most see okay with Class 4.

Can't loose the microsd if you store it the plastic sleeve. Most can be place into a full SDcard holder to make it so. I had one of my 16GB SDHC fail to open the pictures on it back in 2012. Today 2014 I was able to access the data and transfer it off the faulty SD card to the HD then over to my NAS.

32GB find for large SLR or DLR if you take a lot of pictures. Higher than if you going to store a lot of data on your smart phone like Windows 8.1 phone can handle 64GB. I am only using 16GB in it. I have way to many 16 GB would total over 500 GB but again those were for my 40 tablets and 10 smart phones. Each tablet and smart phone needed external storage.

Anyway tech will improve and we have come a long way so far!
