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.

We need to know which file system those cards are formated in order to reach the high speed. If it is exFAT, then those numbers are pointless as all the smart phone storage currently formatted in FAT32 which is much slower.
Awesome, now just tell me how to fit one in my One X.

They have 32gb built in Rom, for me its smart move as I have had probs with sd slots on previous phones
Sent from my HTC One X using XDA
sorry guys I ran thru and posted at all the lte phones I knew off top of my head , I thought only the nexus didn't have an sd card ..
so how will flashing roms via recovery and such work here just never wipe the ext-sd ?

It's a proper partition as opposed to a virtual partition like transformer prime. Wipe is fine, just don't tell it to wipe sd partition.
Only issue at the moment is that recovery doesn't have UMS, so if you don't have a booting OS and don't have backup/rom on phone then you are in a bit of a pickle Will be resolved when recoveries get more advanced. Very early days.

I bought recently a Qtek S100 and i want to buy a 1024 Mb memory card.
A friend told me that MMC is faster than SD is that true???
Tnx for the help
Paulo
other way round, generally sd is better....hence the slighly dearer price
MMC can be more problematic than SD on XDA range in my experience.
I've just ordered a 2GB Adata MMC card to use in my Magician. From other threads http://forum.xda-developers.com/viewtopic.php?t=24988 I've read that the Adata 2GB SD doesn't work but the MMC does. There are also problems with other 2GB SD cards. Speed wise I don't think you'll see any difference even theough the MMC is rated faster since the phones only support the slower interface.
defaultly sd should be about 8 times faster then mmc but some newer mmc cards were suppose to be much faster then older ones not sure
but thing mmc are on the way out along with CF and SM and other older flash types
Well I was thinking MMC was on the way out until I recently looked at buying a card. It seems the latest MMC cards are the "the fastest in the world" at the moment. I think they are being pushed again as some phones (Symbian based Nokias I think) only support MMC and not SD as the MMC is thinner. MMC currently go upto 266x (40MB/second) and the fastest SD I've seen is 166x (25MB/second) mind you the quoted speeds tend to be for reading so not sure how the writing fares.
http://www.geekzone.co.nz/content.asp?contentid=5139
All that said they are only going to be fast when used in a USB2 reader that supports the latest MMC standard. ( I think they need to move a nybble at a time rather than 1 bit )
guess it is a matter if HTC devices support that faster MMC cards then
and if they work if they work at full speed
My MMC arrived today 2GB works fine in my Magician (with orginal ROM). £74 including p&p not bad at all.
As for the 200x speed, this is not supported in my card readers (let alone the Magician). This is because the card supports 3 modes:-
1) Original serial / 1 bit at a time mode (which I think is the one the Magican uses)
2) 4 bit mode one nybble is moved at a time as with newr SD cards
3) 8 bit mode one whole byte is moved at a time and there are an additional 4 contacts to support this.

So I guess I'll be buying a new card reader for my PC to help speed my music copying.
but it would still be slower on the pda i guess
not that the SD interface on any of the pda's can utilize the
speed that even normal SD cards can run at
I've searched for this but no real confirmation:
Would my EVO 4G support a micro SDXC 64GB card? Anyone actually done this?
OR, is there any way to get my EVO above 32 GB of internal memory? Just want to fit all my music...
pretty sure the max for android is 32gb...try it and find out. should be 32 though
Yeah I don't think the evo will handle a SD card larger than 32gb...
Does this even exist yet? I didn't think microSDXC was on the market yet. I've seen SDXC cards, but haven't seen micro.
That said, I really do wish that some of the newer phone coming out would have support for this (since it's backwards compatible with microSDHC cards), just for future-proofing. Then again, maybe cost effective microSDXC cards are still far enough away that it doesn't really matter.
I can not find any 64gb micro SDXC cards available in the world, I'm googling and turning up nothing.
They better hurry, because Apple is about to have 64gb phones and customers expectations will be to match them.
Any updates? I know the 64GB micro SDXC works in the Galaxy S2 phones if you format the card as FAT32. Anyone brave enough to try the same in the Evo 4G?
I'm pretty sure it will work - mine works in my SGSI, SGSII, Sensation, and Transformer.

This is not true. Not everybody wants the same thing. Apple is **** anyway, so who cares what they are coming out with.

We concur with Evo4eva's statement of fact about Apple...it's unanimous!
SanDisk is selling them directly. Expensive, but price will drop soon.

Neither does anything else, but it works.
You need to reformat the card as fat32. This will limit the max size of a file to no more than 4gb.

if you want to be precise, no phone on the market supports microsd (all variation) above 32GB, but thats on paper, sometimes the unexpected do happen in real life, and manufacturer dont like to release these info out.
Hi all.
I have a 32 gb class 6 card (Topram) which I purchased about 2 weeks ago. I partitioned it with a ext2 and converted to an ext3 and had been running Mik 3DSupersonic with a2sd with no problems. Today I was copying the contents of the card to my computer using a card reader and something went wrong. Upon inserting the SD card back into the phone it was unrecognized. I have tried partitioning it with my phone through RA Anon recovery (it completes almost instantly) unsuccessfully and also through my Windows 7 computer without success. Are there any tricks I can try or is this brand new card shot?
Thanks for any insight.
I can pretty much guarantee you have a fake card. Where did you purchase it from?

Really? It was working fine for over 2 weeks. I purchased it through buy.com from a third party seller. I doubt it.
Yeah sounds like a 2gb card hacked to read 32gb until you try filling it up past the 2gb. If you don't mind me asking, how much did you pay for it?

If you're right it had to be bigger than a 2gb because I had upwards of 9 gb on it when it was working. I paid $46.75 Here's the link http://www.buy.com/pr/product.aspx?sku=219375390
I've contacted Topram about a warranty replacement. I'll keep you posted on the outcome.

Topram is really not a very good brand. SanDisk is the only manufacturer that actually has a working 32gb card out right now.

I learned my lesson now. I wouldn't have even considered it except it had very good reviews.
i have a small question about sd cards, i have a sandisk 8gb class 4 sd card that i am using and i used the app SD Tools to test the speeds of my card and my results were as if the class of my card was higher than 4.....but i dont fully understand what speeds are for each class, from what i have read a class 4 should have 4mb of write speed, but mine ranges from 8-10 on the tests...does that mean my card is like a class 8 or 10?...if anyone could clear this up for me that would be awesome...ill put a screenshot of my test results if that would help also...

[UPDATE]
It would appear that HTC's rep's are off their rockers, someone below proved that the 32GB has a microSD slot!!!
It has micro-sd card slot. It's written in the specifications in their website (http://www.htc.com/us/smartphones/htc-10/) and confirmed by every hands-on preview.

Well thank goodness! HTC needs to retrain their support teams!
Actually...their specs make it sound like it is only the 64GB. Do we have visual proof?

Well the first lady on the phone said the confusion was coming from an error on their site. So... I mean I was told twice that the 32GB didn't have it. Do we have actual photo proof of the 32GB with the slot? Although... is the slot with the SIM slot?
HTC needs to clarify this, if I order this and wait 3 weeks to get a phone without an microSD I will be quite upset. As will others.
32GB definitely has a MicroSD slot, as you can see from this hands on:

My phone has started lagging, so I have made a storage benchmark. I have found that my sequential writes are at about 30MB/s.
I find this a bit too slow.
Unfortunately, I was not able to find any other reliable sources to compare my results with.
What is your experience with storage speed?

Here's what I got
Thank you. A huge difference!
Any thoughts on what it would be caused by?
I will try to free up some space and see how it goes.
Our sequential write speed graphs look quite different. Mine looks consistent as it probably writes same file couple of times to test, but yours looks all over the place..
I have tried changing lots of settings, deleting fotos and videos. Didn't help.
Finally I have deleted lots of unused/deep sleep apps. And guess what, the speed is back to normal.
My guess some app tried accessing storage all the time and that interrupted writing as seen in the graph.
Your graph also shows some downspikes, which I guess, is not the best sign for the performance.
I get even bigger numbers, what version you have guys? I have the 256Gb
Mine is 128GB version
128GB, wish i had 256 i need more storage.
