Samsung new UHS-1 series microSD for LTE phones - AT&T Samsung Galaxy Note I717

Samsung's memory cards were updated late Wednesday with large-scale production one of the world's fastest microSD cards. The new 16GB microSDHC card runs at the same UHS-1 (Ultra High Speed-1) spec normally used for the latest full-size SD cards, giving it performance that would previously have been reserved for pro memory for DSLRs and video cameras. Sequential read speeds peak at about 80MB per second, or roughly four times the 21MB of regular microSD cards.
The storage is ostensibly meant for LTE-capable smartphones and tablets, where flash memory speed could bottleneck the connection. It should nonetheless be useful for cameras that take microSD storage and support UHS-1. Samsung reached the density through a combination of its more recent 20-nanometer manufacturing process to build 64-gigabit (8GB) chip layers as well as a toggle DDR2 interface that can saturate the newly available bandwidth.
Release schedules and prices weren't given out, although mass production usually precedes a launch within a few months or less.

Do want.

Sweet!! I just picked up a 32GB microSD. If the speeds are noticeable better then I would consider purchasing
Sent from my SAMSUNG-SGH-I717 using XDA

me too kasanRio me tooooo *insert quiet yet evil laugh*
agent2702 I think they really will be much faster 20nm tech is like ssd or some ishh isn't it .. 80mb/sec is pretty nice
I honestly wouldn't need anything larger than 16 and I actually like when my gb of my card matches my phone's internal storage for a total "nice round number"
doubt I would ever record a movie bigger than that not with my phone anyways

That's great... I've seen the UHS-I technology in action on DSLRs and it's great. Makes a huge difference if fluid 720p recordings.
That said, UHS-I cards require UHS-I capable readers. Outside of DSLR cameras, very few devices have UHS-I capable readers, and such readers are rare even on PCs.
If you put in a UHS-I into a non-UHS-I capable reader, then it defaults to a lower speed. I had this discussion earlier when pursuing a Sandisk SD Card that had a UHS-I rating as a Readyboost card for my friend's netbook. Support said that since the netbook didn't have a UHS-I reader, the card speed didn't default to Class 10, but to class 6. So far, I believe this varies from card to card.
To sum this up, do we know if the Samsung Note has a UHS-I capable reader? As far as I know, this hasn't been advertised as a feature. Further, I'd surmise that since I haven't heard of people advertising software updates for their readers upgrading to UHS-I, I imagine readers need different hardware to be UHS-I capable.

I believe they are just calling them UHS class but all new tech based on the article . just stating that they are the equiv of digi cam cards speed and performance wise but for phones ..

@shoobie:
I appreciate the article, but, I'm going to attempt to clarify on what's required for UHS-I cards. Oh, sidenote, I didn't take enough time to look at the picture to note that the cards default to class 10, which is good .
Well, what they're saying is that UHS-I hasn't been effectively implemented into the microSDHC form factor yet, only the SDHC, as DSLRs and the like use SDHC cards or CF Cards (Since DSLRs often have enough room for a larger card reader, since you often lose performance and/or increase the price dramatically when you miniaturize components).
For UHS-I to work, according to the SD Part 1 Physical Layer Simplified Specification Version 3.01, it requires that both the host device and the card be UHS compliant. Summarizing off section 3.9.4... essentially in the past, host devices communicated with the SD card via 3.3 Volt signaling. UHS uses a special 1.8V signaling at a higher speed to communicate with UHS compatible cards.
Now, I'm no engineer, and I haven't gone through the document thoroughly enough, but as far as I can tell, it's not a soft update for the card reader, but a hardware update (or basically a new reader is needed) to be UHS compatible. This theory comes from the fact that I haven't seen anyone announcing card reader updates or flashes that allow their readers to now read UHS-I cards.
The real question is: Did Samsung have the foresight to equip our Galaxy Notes with UHS compatible readers?
Otherwise, they're just setting these cards up for the next generation of phones that will definitely be UHS compatible.
Not trying to be a party pooper, just saying >,>

Someone here says that Samsung told them the Galaxy Note *does* support the UHS-1 microSD cards with their higher speeds.

Hope you don't mind my skepticism, but... after reading the post... it reads that "Samsung finally gsve me an answer, it is compatible. "... which doesn't really mean much. UHS-1 cards are compatible in older SD card readers, but said readers do not utilize the new higher speeds for the UHS-1 speed class.
Though, who knows, Samsung might... I'll try to contact them soon, though uh, who knows when I'll get a reply, anyone else want to give it a shot?
Remember, you don't want to ask if it's compatible, you want to ask if the reader is SD Card 3.0 compliant, and/or if it's a UHS-1 capable reader, and capable of reading UHS-1 cards are UHS-1 speeds.

My thoughts, exactly.
The guy did talk about buying such a memory card and experiencing faster speeds with it later down in the thread, though.
