Here's my CDM results:

--------------------------------------------------
CrystalDiskMark 2.2 (C) 2007-2008 hiyohiyo
Crystal Dew World : http://crystalmark.info/
--------------------------------------------------

32GB Lexar	64GB SanDisk
Class 10 UHS Class I
microSDHC	microSDXC

Sequential Read : 261.447 MB/s	313.112 MB/s
Sequential Write : 534.885 MB/s	432.224 MB/s
Random Read 512KB : 513.374 MB/s	519.218 MB/s
Random Write 512KB : 982.998 MB/s	791.061 MB/s
Random Read 4KB : 5.389 MB/s	3.569 MB/s
Random Write 4KB : 360.648 MB/s	295.704 MB/s

Test Size : 100 MB

I ran both tests on the same machine, using the same SanDisk USB card reader. These numbers seem about 10x higher than I'd expect, but they still show that the microSDXC has faster reads & slower writes than a class 10 microSDHC.

Your CrystalDiskMark results are useless since you didn't turn of cacheing all we see is bloated burst speed from your ram , none of these flash cards can get in triple digit range.

Got mine today, phone formats it to fat32.

Nice, two confirmations now! Mine should arrive tomorrow, day after at the outside!

I heard it also works with NTFS using fuse module !
[Galaxy S II Accessories] Trev186:
What is that?
[Galaxy S II Accessories] tuvi123:
if you want NTFS with your 64gb sdxc / 32gb sdhc etc.. (after you format it to ntfs) :

1) read these (the compiled module + inst):

2) also take a look on this kernal (it has ntfs support):

http://xdaforums.com/showthread.php?t=1263838

it works also on the 64gb sdxc as I have heard (for me it works on my team 32gb sdhc bought from ebay, I can copy 10gb hd files and watch them with my phone, also works with mhl cable on my tv)

make sure your kernal support tthe module and make sure they were built from the same sources (all 2.3.3 kernals that are from samsung update 1 sources support this, however 2.3.4 kernals built from update 2 source need a new compiled fuse module).

Calling anyone with a SGS2 and an Evo 4G

If someone has an EVO 4G lying around, can you try the FAT32 formatted 64GB sdxc card in that phone? I'm wondering if it will recognize the entire 64GB space. Thanks!
[Galaxy S II Accessories] Trev186:
This works on the Evo 3D !!!! LOVING IT Now I can ALMOST fit all of my PS1 games!

:D

I imagine this will work with most phones as long as you format it correctly.

The only issue I had was I have the CM7 alpha for my Evo 3D and it could not reformat my SD card

I swapped to my wife's non rooted phone and it formatted the card properly.

I honestly think this belief that our phones would not work with SDXC cards was a misconception because all the manufactures marketed them as "up to 32 GBs" They did that cause that was all that was around at the time.
[Galaxy S II Accessories] NZtechfreak:
Confirm mine is also working, loaded 47GB onto it so far.

I'm certain you are right Trev186, ever since the 4GB ones came out I have always been amongst the first to adopt the new ones and they have always worked despite the marketing (which I agree is because the older ones were previously the highest capacity). I thought it could have been different here since its a new standard, but apparently not. Will try in SGSI, Transformer, and Sensation tonight.
[Galaxy S II Accessories] 3waygeek:
Your speed numbers look about 25-30% higher than I've been seeing; are you overclocking or running a custom ROM?
[Galaxy S II Accessories] punshkin:
haha my friend who spend tons of money on the 32GB iPhone4 is raging all over the place now :D

especialy since 32GB prices are about to drop LOW :p

Leomars rom , phone is not overclocked , alittle undervolted. CPU speed will not affect IO operations that much , but Kernel Scheduler will i am using "CFQ" good balance for IO and CPU operations.
[Galaxy S II Accessories] NZtechfreak:
Ah, thanks for that, your benchmarks are also a bit higher than mine...

Incidentally - this card works in my Sensation and my GF's SGSI too.
[Galaxy S II Accessories] RMXO:
Thanks for the reviews & feedbacks. I'm so going to get this card for my Galaxy Note when it's released.
[Galaxy S II Accessories] :
Any chance you have an EVO 4G you could test it on?
[Galaxy S II Accessories] NZtechfreak:
Sorry, I don't have one :( To be honest I'm kinda expecting these cards to work in lots of devices now that its worked in everything I've so far put it in.
[Galaxy S II Accessories] darks1der:
Works fine on my DZ, I'm running the myvision4G rom.

Thanks for the heads up

Just as a side note, where did you get that battery meter in the notification tray?
[Galaxy S II Accessories] chiefroastbeef:
That is the Leomar (well now, CheckRom Revolution) Rom with the Super Revolution theme. Absolutely the best rom and kitchen app out there.

I will see if the Transcend and Kingston 64gb micros are any cheaper. :) I would love to load the Office season onto the the micro SD, my music takes up my 32gb card. It would be awesome for plane rides.
[Galaxy S II Accessories] misterxzibit:
Can someone use the fuse module or whatever, and format his 64gb microsdxc card to ntfs, then do a test so we can see any read/write speed improvements ?

Hi,

pls post a benchmark for the NTFS formatted card.

Thank you
[Galaxy S II Accessories] Evo4sickness:
Whats up 3waygeek thanks allot for posting this I read through all the posts and didnt find anyone trying and confirming an Evo4g working with this and really wanted to know if anyone has done it before I buy the 64g thanks let me know since its been while since anyone has posted on this.
[Galaxy S II Accessories] Trev186:
I don't have an evo 4g BUT sdxc did work in my nexus one once the card was formatted properly.

The nexus one is older than the evo 4g and also made by HTC so I am pretty sure it will work.

The only issue you may have is your phone may not know how to format the SD CARD to fat 32

In that event another phone may be able to format it for you or you can try a pc application to format it to fat 32
[Galaxy S II Accessories] Evo4sickness:
Ok great thanks for info yeah if it worked with the N1 than the Evo should have no problem for sure.

[Galaxy S II Accessories] 3waygeek:
The SanDisk is billed as being UHS-1 and having read speeds up to 30 MB/s, and is available only at that speed. The Kingmax is supposedly available in class 6 or class 10; however, I haven't seen any of the class 10 Kingmax cards for sale anywhere.

FWIW, the SanDisk gives me SD Tools ratings of 5.9 MB/s write, 18.1 MB/s read.

thanks for answers and help
[Galaxy S II Accessories] Evo4sickness:
Yes a british person he was the one that started to try this out with a allot of different phones.
[Galaxy S II Accessories] Trev186:
Listen all u gotta do is put the card in your phone.

It will say "cant read it do u wanna format it ?"

The reason being is cause it is formatted as exfat instead of fat 32.

Your phone should then proceed to format it after you say yet and it will then be fat 33

I have done this on even a nexus 1 so I am sure it will work.

As for buying cards for cheap from other sources be aware cause there are a lot of fake cards being sold

bought one the other day at that price it turnt up yesterday and works great , much faster then my sandisk class4 card too
[Galaxy S II Accessories] Evo4sickness:
These new ones are all rated at class 6 right. I Figured they have to be to be running 64gs
[Galaxy S II Accessories] buxz777:
yeah mate mine is class 6 , transfer speeds are between 6-7mbps when i transfered my 32gb card data across to the new 64gb card via my pc

it took just less then 1 hour to transfer about 28gb of data which i was very happy with (movies/pics/mp3s)

just be carefull of fakes that will no doubt pop up soon enough , amazon direct is a great place to buy from , it is 110% genuine

as others have said just format it via the phone 1st in -- settings -- storage -- sd card , this will put it into fat 32 ready to be used :-)

Micro SDXC works in SGS2 ,However just so you know "Transcend Ultimate SDXC" is not "MicroSD" but a full size SD card , it will not fit in SGS2.

ah yes i dont know how i make mistake must be tired after work....thank you :eek:
[Galaxy S II Accessories] iromek:
Series, Movies, Music, Videos... 32GB is not that much. I'm hoping that the SGS3 will have a 32GB or even 64GB memory built in option (with MicroSD exp of course for even more). This is the main reason I won't even consider the Galaxy Nexus and why I was so very disappointed in it.

---------- Post added at 03:49 PM ---------- Previous post was at 03:44 PM ----------

They are, in fact, NOT correct. Micro SDXC will work on our SGS2 but here is what happens. You put the new 64GB card in, the phone says "sorry can't read this card, would you like to format it?" you say "yes"... the phone formats the card in Fat32 format (since it can't read the new file system the XC cards come with). And you end up with a working 60GB card (you lose 4GB ---almost 5 in fact--- due to Fat32 sector size). In fact I believe you end up with 59G working space on the card. With 128GB you'd end up losing about 9GB of space due to FAT32.

In theory if Samsung (or someone else) added the FATx (I believe that's the file system XC uses) compatibility, the actual MicroSD reader would be able to handle the cards without a problem. This is purely a software limitation not hardware.

The other issue with 64GB MicroSD cards are that they cost in the area of £100 so WAY too much... :cool:
[Galaxy S II Accessories] sammyx:
really i hate today sellers politics with unresonable, stupid and crazy prizes , 64 gb micro sd cards are not aspect ratio with price, about 3-4x more costs than 32 gb.....:mad:
[Galaxy S II Accessories] Trev186:
Thank u for sharing my concerns.

I am hoping for a 128 Gb sdxc card this year...seems they release a new size once a year.

[Galaxy S II Accessories] cowbutt:
Not really - if you compare like with like. A cheap 32GB SDHC card can be had for £20 or less, but a quality one (e.g. Samsung Class 10) is £35+. So a 64GB SanDisk uSDXC at £75 is only just over twice the price of a quality 32GB card.
[Galaxy S II Accessories] Evo4sickness:
Which would make perfect sense. Rember that the technology to do even make these Micro sd cards is no joke no to mention the durability you get with the Sandisk. I know its easy to forget what become the Average in technology but look up how sd cards are made and how they work and you will understand how amazing that little peice of metal and plastic really is.

They know how to make the card report a higher number

And what I will lose with formatting USB storage, what is included in that? Can I format card on PC to fat32 or is better on S2 do it?

Else my S2 is new.

PS. Is this true: "The only issue I've found so far is that the camera doesn't seem to be able to work out how many minutes of video or pictures can be taken with the available storage" ???:confused::eek:
[Galaxy S II Accessories] Trev186:
Root is not required.

Shove the card in your phone and let it format it. I had a hard time finding an app on windows to format my card to fat 32 from exfat.

Formatting your ext sd card wont affect your internal storage. Once the card is formatted just transfer all your files to your new card and then reboot. It should be like you never changed the card

Problems

Hi folks,

I've had some issues with this. I unmounted my previous SD card and popped the 64gb one in.

I got the warning I expected in the notification bar, and although it mentioned USB storage - not SD card - and I wound up wiping the internal USB storage. Not the end of the world - just some music that I've got backed up was lost - but it didn't touch the SD card. I can't mount the thing, I can't get the S2 to format it... any ideas?

Running Resurrection Remix 1.0 ICS ROM, i9100.

---------- Post added at 06:07 PM ---------- Previous post was at 05:36 PM ----------

I'm reformating the card in Windows, I'll see if that helps.
[Galaxy S II Accessories] dadyal:
i saw a video on youtube few days back the guy used a sandisk 64Gb card in SGS2 he put the card in and then formated it within the phone and it was working
[Galaxy S II Accessories] Trev186:
I had this problem before as well. Are u running a custom rom ? When I had a phone with CM7 the auto reformat feature did not work.

To resolve the issue I popped the card in a stock phone and had no issue.

As long as u bought a card from a credible source it should work fine

Just saw ur running a custom ics rom.

U might wanna flash back to a stock GB release and try it there
[Galaxy S II Accessories] GoatApocalypse:
Thanks Trev. I'm not hugely confident when it comes to flashing ROMs at the moment, especially since in Resurrection Remix it seems to boot into standard Android recovery mode and I have to install CWM from there... it's a bit confusing!

I'm sorely tempted to factory reset the thing and start from scratch.
[Galaxy S II Accessories] Trev186:
Do u have and old android phone lying around?

If not go to best buy and buy a phone full price power it on pop the card in and format it. Then just return the phone :)

I'm pretty sure that would work but double check their return policy.

U could also mention it to the rom dev
[Galaxy S II Accessories] Trev186:
Or I think if u let windows format it to ntfs there is a way to make android work with ntfs ....but never tried it myself.

If u have windows vista or xp I know there is an app to format things to fat 32 from ntfs (ur card is exfat so it needs to change to ntfs first)

The fat 32 formatted app sadly does not work on windows 7

So plenty of people seem to be able to get SDXC cards to work on their SGSIIs. I can't...

See for example: http://xdaforums.com/showthread.php?t=1274789

I'm using the exact same card (SanDisk 64GB SDXC microSD) and the exact same phone as in the OP in that thread, but even after I click "Format" and the phone seems to go through the formatting process, it gets up to "Checking SD card" and then just stops. If I click "Mount SD card" again, I just get the same "SD card damged. You may have to reformat" message.

Anyone else had the same problem? Anyone found a solution? The only thing I can think of that might be causing the problem is the particular custom ROM I'm using: CyanogenMod ICS 9-20120319-nightly-galaxys2. Is that likely to be the cause of the problem? Will I have better luck if I change to a different ROM or go back to the stock firmware?

Any help much appreciated.
[Galaxy S II Accessories] 3waygeek:
If you haven't done so already, try formatting the SDXC on a Windows box before sticking it in your SGS2.
[Galaxy S II Accessories] fida khan:
Hi guys. Got a a couple of questions. Would a 128GB card work and if it does would there be a drop on speed ( I assume there should'ntbe cos they're the latest mem cards so they should have fast speeds)

The reason I'm asking cos I've got a ptn 32GB card and if I'm going to upgrade I might as well go straight to 128GB. And why do some posts say that they can't FORMAT to fat32 .is it because they have flashed a ROM? Finally will a 64 or 128GB work if it's formatted to ntfc ?. Thanks

DON'T MESS WITH STEWY GRIFFIN ! (What the ....!) Sgs2
[Galaxy S II Accessories] Trev186:
Well fist of all to my knowledge a 128 GB micro sdxc card has not yet been released.

Secondly if SDXC works in ur phone now it should work for all sdxc related sizes...current limit is planned for 2 TBs

Third the only reason I have seen that people's phones wont format the card is because the custom rom they are running takes that feature out or breaks it. Which is understandable because how often does anyone use that feature ?

Even in the example above the guy having the issue has the same phone as me....he cant format it but I can. We are on two different roms
[Galaxy S II Accessories] fida khan:
Thanks trev. I did think 128s were out. But I'm sure I read somewhere in this thread that they're out! Thanks for clearing the ROM thing up. I'm on stock GB 235. So I guess I should be ok to format a mem card.
[Galaxy S II Accessories] Trev186:
Fida

128 GB SDXC cards do exist....just not the MICRO sdxc. U need a micro sdxc card to fit into ur phone
[Galaxy S II Accessories] Chairmansaab:
Hm Is 64gb Available in Indian market ? or It is available online currently ? Btw will it work on ICS ?
[Galaxy S II Accessories] fida khan:
Yeah! imagine ordering a 128GB online and THEN finding out it's the wrong one!!! What the deuce....
[Galaxy S II Accessories] Trev186:
Buy from amazon or san disk direct. I have never seen them in stores.

Also yes it works in ICS I'm using ICS.

There really is no issue I have come accross on any phone which prevents these working besides the initial reformatting the cards need.

Everything else about devices not supporting it is just based on false assumptions cause all the marketing material says up to 32 GB cause sdxc cards are not mainstream yet...basically they reference the largest card that sdhc offered ...
[Galaxy S II Accessories] GoatApocalypse:
Still no luck for me! Reformatted as both exFAT32 and NTFS using Windows 7, and the SII still won't have it.

I'm convinced the ROM is confusing it with the USB storage but I haven't got the courage to try to flash something else, or to go back to stock.
[Galaxy S II Accessories] fida khan:
So do you have 64gb card. You said your phone doesn't format. so did you format on PC and if so which OS ?
[Galaxy S II Accessories] Trev186:
My phone formatted it just fine.

I just know from exp on another phone I had which was running a cm7 alpha that the rom did not allow me to reformat the card
