Samsung Introduces 64GB UHS-I microSD and SD Cards
by Stefan Constantinescu on August 29, 2012 8:04 AM ESTSamsung has just announced two new memory cards, both capable of storing 64GB of data. One is a full sized SD card, suitable for devices such as cameras and camcorders, while the other is a microSD card, perfect for use inside a smartphone or tablet. Said cards are UHS-I certified, with the full sized card being able to deliver 80MB/second read speeds and 40MB/second write speeds. The smaller microSD card is said to deliver 70MB/second read speeds and 20MB/second write speeds.
Both cards use 20 nanometer 64 gigbit NAND chips and they're expected to hit the market in October. Pricing information hasn't been announced, though it's safe to say that they're not going to be cheap.

SD cards that behave more like SSDs will become more important as mobile devices get faster and faster. Many of "modern" SD cards are just plain horrid when it comes to random I/O.S_Constantinescu - Wednesday, August 29, 2012 - link
The thing is more and more devices are now sealed, so ... what's that going to do to the expandable storage market?Lonyo - Wednesday, August 29, 2012 - link
Well, Samsung make phones as well as flash, and they are one of the few with a MicroSD slot on their high end phones (e.g. S3).While many others may be neglecting MicroSD cards, Samsung will typically have an incentive to include a slot for one on their own phones, which are also some of the most popular phones, so it's not like the market will disappear.

I'm not sure what is meant by 'cheap' here but they won't be able to price them extremely high either. Sandisk has 64GB UHS-1 microSD cards that go for roughly $1/GB. Even if the claimed specs are different because of different UHS implementation, they will have to compete with those cards.mwarner1 - Wednesday, August 29, 2012 - link
I was wondering what the difference was between these 64GB cards and the (Red/Grey) Sandisk 64GB UHS1 MicroSD card currently living in my Samsung Galaxy Note was, so had a look for the file containing the benchmark I did on it.My card benched as follows:
12.8MB/s write
34.1MB/s read
I guess 20 / 70MB/s is a nice improvement ... although not really necessary in my phone I wouldn't think!
I also wonder how they will market this, as both cards will just be labelled UHS1 and the average consumer won't know the difference.
