Get it while it's hot! (in stock as of 8:19 EST) :good:
DEAD as of 3:00 am EST

Got it ordered. I check it every morning waiting for that price. I will have a 32gb Class 10 for sale on Wednesday!

Thanks, I have been on the fence with 64 gig so many nock offs.... Order is placed

Guys, be warned that SGS3 DOES NOT support UHS-1 (i.e. class 10) cards.

There's a thread some on here where the exact card is supported.

does not support, but it works fine if you format the card in the phone. exFAT does not work, however, so you are limited to files < 4gb in size. Kind of defeats the purpose of having such a large microsd card though

UHS1 is simply a speed classification typically used by high power cameras. C10 refers to the minimum write speed of 10mb/s.
This card will work in exfat format for stock GS3, however cwm or twrp recovery only supports fat32 which this card will format to.
I have used this card before so don't be reluctant to to purchase it.

I have been using this exact card since the date I got my GS3 (mid June). It works well with everything and never crashed. It also works with backup and restore within CWM. YMMV though. It is exFAT formatted.

Phone will format it as fat32 and all will be fine. Tested and works well.

What are you guys talking about? Have anyone actually tried this out?
I have this exact same card UHS-1 Class 10 (not the old Class 6 one) in exFat format and everything works fine in CWM and in Android.
EDIT: BTW, I formatted the card with SDFormatter on my PC, not on the phone.

S3 doesn't support UHS-1 speed but it does support exFAT format. The card itself came as exFAT, S3 won't even ask you to reformat it as FAT32. Just pop it in and everything works 100%.

Sweet, just nabbed one. I check the price every day also and was just about to post it here...beaten to the punch as usual .
ps anyone want to buy a Zune80gb heh heh

Is there a good way to utilize an "external" sd card to store apps and nandroids? It seems like the GS3 (and maybe just ICS/JB in general) is setup to use the "internal" sd for everything.

Yes, the latest version of cwm official supports internal and external nandroids.

Cool, thanks. Any idea about Play store apps? I checked the reviews on Apps2Sd and they were all complaints about how it can only see the internal memory partition.

SD formatter is awesome software. I had issues with a 4speed card jumping in my canon. The SDformatter, made it stop. Dunno how it works, but it does.

Saw this on another android blog this morning and picked up a 32 for the gf, and a 64 for myself. Thanks for posting guys.

Too bad it can't be shipped to Canada. :crying:

Be aware!
I bought the very same card at the beginning of the month and after 2 days of use the Card stopped working...
The card became unusable and I had to fill a claim with Amazon since the seller didn't reply to any of the emails I sent...
Just my experience guys...

[Q] Everything to know about Sandisk 64 GB microSD card.

I should be getting one today so for right now I'm just asking questions to be prepared for when I do get it. What should I know about it?, What should I format it in?, I heard you can't have apps on it, is that true?, etc.

I just got a 64 GB sdxc card last week. I'm running PA with a CM10 base, which doesn't support exFAT. So I've had to format it to FAT. It does work like a charm though.
Sent from my SGH-T999 using xda app-developers app

It should come formatted as exFat, if you intend to use the card on Touchwiz based Rom's and Windows XP+ operating systems, that will be fine. If you want greater compatibility or intend to run CM10, you need to reformat with FAT32. The only real downside with FAT32 is that the max file size is 4GB. I highly suggest using the SD Card formatter. https://www.sdcard.org/downloads/formatter_3/
Enjoi the new card.

I would recommend sending it back. Formatting a 64 GB micro SD card was a bit useless to me as it's performance was awful and functionality was lost.
Its like buying a Ferrari and putting a ford focus engine in it. Do not waste your time formatting it to FAT32.

Any proof of this? I don't believe there is any appreciable performance difference between FAT32 and exFAT. Again, really the only functionality LOST from going from exFAT to FAT32 is the 4GB file size limitation. I can't remember the last time I came across a file that size. You do gain compatibility with almost every modern OS and almost all embedded devices (cameras, printers, etc etc) by going to FAT32 however.

Yes there is proof all over the internet. This is the first thing that came up when I went to Google. http://www.differencebetween.net/technology/software-technology/difference-between-exfat-and-fat32/
Having a 64 GB micro SD card formatted to FAT32 will be a degradation of overall performance. FAT32 is not optimized for large disks and read write speeds are effected because of block sized on the disk and fragmentation of files. If you don't believe me, just go buy one and see how it performs.

Even in your link it says very little to the performance differences between the filesystems. Also keep in mind FAT32 was very much widely used with traditional hard disk drives well past 64GB with little issue.
Fragmentation can and does happen with all modern filesystems. Remember when Microsoft touted NTFS to be fragmentation proof? Again, if you look at the link I posted, it has graphs and charts showing little to no significant performance difference between exFAT and FAT32.
Fragmentation is also less of a concern because the card in a SGS3 is strictly an external storage device, not a random read-write access system partiton.
I have 4 of these cars and love the extra space they give me. They have proven to perform at least as well as any 8, 16, or 32 GB card.

Just got it and I don't see why people make this seem like it's so difficult to use. I put the microSD card in the phone and that was it. I started to move some songs from the phones internal storage to the card. I swear I came across so many threads where people acted like you needed some sort of full page tutorial on how to use it. I understand if you're using different ROMs but if you're just using the Stock ROM there's like nothing difficult at all.

Hello, so I received my 64gb sd card also and everything seemed to work perfectly. I had backed up my old 16 gb card and copied songs and pictures to the new one.
Then it started to act up on me. I would be listening to music and after a while my phone can't read the sd card anymore. It would tell me that the music file was not the right format. I also checked the sd card with the file browser and it shows nothing on the card.
I have read that people have trouble getting the phone to read the sd card from the get go saying that it's corrupted but I don't have that problem. Mine reads fine but then stops. I have it as exFat and also have formatted through the phone but no luck. Would formatting it to FAT32 fix the problem?

So far I haven't experienced any problems and hopefully it will stay that way.

I had just went thru this with a new 64GB msd card and fubar'd it beyond belief. I tried putting the card into my PC and it said the card was corrupted, formatting it would not work/fix it ~ in short it was a PITA.
I exchanged it for another.
Once I got my new card I promptly put in my Galaxy Note (which will tell you that the card is not reconized and needs to be formatted), formatted the card, put my phone into UMS mode and transfered all my files to it. Once that was done I took the card out of my Note and put it into my SGS3. The card no longer has problems going from SGS3 to PC to any other device and I get all my storage space. Problem solved.

So this thread has been dead for some time. Sorry for the Jack, but no point in opening a new one since this one has some useful info in it.
Here is my deal. I bought a 64gb SanDisk on Cyber Monday bc of some link that someone put on here. Got a great deal - $38 but it was on back order for flippin ever and I just got it the other day. I have already reformatted it and copied all my crap over to my PC waiting for it to be transfered.
I am running a personal kang of LiquidSmooth RC7 with LeanKernel v1.6 (they are by far the most stable combo for me). The problem is that it will not mount the 64gb card. I always thought it was Kernel dependent, but not so sure about that anymore.
*I have switched to KT's kernel and it doesn't mount it either.
*So just to do some checking, I mounted it in my tablet (Transformer FT101), worked fine.
*Is seen and recognized in my PC.
*The guy that sits next to me at work has a VZW SGS3 (Stock/non-Rooted) and it shows up just fine.
*I flashed Darthstalker (Twiz) and it showed up.
*I flashed Xtremepedia (CM10 base) and it did NOT show up. Tried stock kernel that came with it, LK and KT kernels and all 3 were a no go.
So what I know it that it will work with TWiz (but we all knew that anyways), it will not work (for me at least) with KT or LK kernels. I abhore TWiz ROMs (No offense to anyone but I like AOSP better/ not a big fan of PA or PAC-I already have a tablet).
Here is my question. Is anyone running an AOSP ROM and using a 64gb card? I will be downloading and flashing these this week but wanted a jump on one that someone knows for a fact (meaning they have a 64gb in their phone now) is working.

You can use the 64GB card, you just need to reformat it as FAT32 instead of exFAT. Yes I have a 64GB card now, Yes I've used it with a plain vanilla AOKP/AOSP Rom both in my SGS3 and in my Sensation previously. All worked fine if the card was formatted as FAT32. I highly suggest using the SD Card Association formatter utility. https://www.sdcard.org/downloads/formatter_3/ I also like to stick with 32K clusters for Android, works well for me.

my 64GB card was working fine for awhile in my S3, stock and FreeGS3 r6 and r7.
All of a sudden a few days ago it failed to mount. i'm sure FAT32 will work i'm just extremely curious why it stopped.

FYI, here's my reasoning behind the 32K clusters. This bug may or may not still exist in 4.x, but I don't really care, I'd rather avoid the whole thing than to test it out. Call me lazy. Again, the best way I've found to do this is to use the aforementioned formatting utility, it will let you format FAT32 partitions larger than 32GB and let you choose the cluster size.

Pretty Much the Same problem
I am running liquidsmooth RC9 with leankernel 3.0.52 and my D2TMOB refuses to mount my 64gb SanDisk. I flashed the stock rom back the sd card works just fine. Then I flashed back liquidsmooth and formatted the card to fat 32 and it doesn't even recognize the card. When I format it back to exFat it tells me I have a damaged card. Can you someone please point me in the right direction?

I am sorry I won't be too specific but I read somewhere on xda that aosp based roms will not read extFat because it is a proprietary format. So one has to format one's extSDCard to fat 32. The easiest way to do that is downloading the GUIFORMAT software from the following link W W W. ridgecrop.demon.co.uk/index.htm?guiformat.htm. Makd sure you fixed the typos on thatt url... The only way I can post a link. Once you format it to fat 32 and you are done. Just insert the sd card on your phone, mount it from the storage menu, and start enjoying your extra storage.

I bought this card on black Friday for only $30. I just put it in and it works fine. Sandisk also makes an app which you can see everything on your phone and sd card easily plus ability to transfer files to either one really easy. Highly recommended only of you can get it for a good price. In Canada at best buy etc its like $200 which is insane.

just had a 32gb sandisk ultra micro sd die in sg4

Bought this ultra micro sd class 10 sandisk about a year ago. Had it in my htc amaze until may 1st when I got the s4. Today my sd dissappeard. I ejected and inserted multiple times but the phone wont even acknowledge it has a sd card in it. Bought a new identical sd card and it was recognized right away..
plugged bad sd into computer and the computer didnt acknowledge having it plugged in until the 5th time I tried.
was able to copy all my files thank god. 24gigs of work and info almost lost..
anyone else think the sg4 did this some how or could it just be a rotten sandisk micro sd?
input greatly appreciated.

SanDisk had issues with the 32/64GB MicroSD's; im on 64GB number 3 right now, which has worked fine for about a month (the first two would randomly dismount usually once a day on my Atrix 4G and also stop responding on my PC randomly), this one does not. Try getting it replaced or getting a different brand. Normally SanDisk is pretty rock solid (i use sandisks exclusively at work as they are the only certified cards for the recorders i use, and the only brand ive never had problems with. i use mostly CF and also sometimes SD/MicroSD)
Honestly i think the MicroSD thing is all SanDisk related; specifically to 32GB and 64GB Class 10's (the gray/red units). The older 32GB Class 4 black MicroSD's dont have issues.

Crazy update. 2nd 32gb ultra micro sd un mounts and mounts every 9 seconds. Or if you tap the card or shake/move phone slightly it un mounts and re mounts.. I put in a 1gb sandisk black class 4 micro sd and shook and tapped phone over micro sd and it did not unmount at all stood in fine.
this is terrible quality on sandisks behalf. I dont even know if I have receipt for them. I bought both at bestbuy tho...

I bought a SanDisk 64GB microSD card at BestBuy. So far so good works like a charm...*knocking on wood*. I had a 32GB Lexor that I used in my Sensation 4G and it died on me after about 2 years. Was not able to recover the data either. I did backup the data every 2 - 3 months, but still lost a lot of data. :crying: With the S4 I'll probably end up backing up data about every 2 weeks just to be safe. The free 50GB from Dropbox came at the right time.

I bought a samsung 64gb since i read a bunch of reviews that said the Sandisk 64gb would randomly lose all the data on the card and the card would just die. Some said a week after getting it, others said months. I didn't want to risk losing all my pics and stuff

Glad I'm not the only one having issues. I bought a 32GB card and had a bunch of issues with it. It would unmount randomly and the gallery was always slow to load up the contents. I bought a 16GB one and it's been fine. Very fast to load, no issues. I ran an hour long SD card test on it Saturday and it passed with no issues and decided to try it again and so far it's been perfectly fine.. Weird.

i had the same issue with my S3 and my SD card it would just become unreadable out of no where..
if your stock then the only reason i can come up with is nolonger valid
I think i'm going to start utilizing these instant sync apps (G+, Dropbox) just out of fear of losing pictures

There are already multiple threads on this. if you get a damage sdcard warning, plug the card into a PC, open cmd & type chkdsk /r /f <drive_letter>. it will take time to fix your sdcard. Backup your data & reformat if you wish. I get this occassional but with chkdsk I'm have no worry since I can repair & already have backup in place.
With that all said, it is disappointing to have to go through this. What I noticed so far is that it's only happening on my exFAT & FAT32 formatted 64gb sdcard for me. I never had this kind of issue on my 32gb sdcard.

I think this might work
I've been having issues with my 64gb sandisk ( unexpectedly removed error ) & remounting or formatting has not done the trick until now. Formatted card to fat32 with my PC which I have done multiple times & still had issues, but now after a fresh format to fat32 using my PC I decided to format with OUDHs recovery under mounts and storage - format extsd & have absolutely no issues as of yet. No more errors finally. Lmk if it works for you guys.

Thats weird. I've had the same problem with my 32gb sd card i thought it was just the sd card but it seems like a lot of other people are experiencing this as well...

So which Micro SD card DOES work? Please Report in.

I thought I would start a thread on which Micro SD cards were recommended vs. those that fail early or are simply not compatible. I saw a thread earlier that appeared to show that some cards (and sizes) were better than others.
I can report that the Samsung 64GB card (says Class 10, HC, 24MB Read, 7MB Write) does NOT work in this tablet. I was able to use it just fine in my Note 2, and a laptop. However, the card doesn't work properly in my 2014 Note 10.1. An older Pansonic 16GB MicroSD card worked just fine however. I've tried formatting it in other machines, and it's still a bust. Currently, these cards are selling like wildfire on Ebay for $30.
So, what DOES work for a 64GB card? Any help is appreciated by myself and I'm sure a lot of others reading this forum.
Thanks in advance.

I have got a SanDisk 64GB card in mine. Also got the same type in My Note 3.
The SD card issue seems a bit odd, both of my cards were also fine in my older Note 10.1 and the Note 2. I've never had a problem with either of them

Hey guys, thanks for the info. After some research I discovered that this was indeed a fake card I ordered from Ebay. Looks like this is a common problem as the packaging is *almost* perfect and you really can't tell the difference without some serious research. Luckily, the seller refunded the full amount back to me. Based on your feedback here I've ordered a SanDisk Ultra from Amazon.
Thanks for the help and & Happy Thanksgiving!

A really good way to check them is to simply try to fill it up. Only 4G of data will be saved and readable, whereas the other 60GB is corrupt.

It's sad that a lot of people get duped into buying fakes. But sites like ebay don't/can't do anything about it.
Memory cards/Usbs should only be bought from reputable sellers only (Amazon, Currys, Play.com etc) as there are wayyyy too many fakes out there.

I'm currently using a Transcend 64GB SDXC UH-1 Class 10 card which was formatted using the tablet.
It works fine except for one annoying problem. When transferring large, singe or multiple files, say 1.5GB+ HD movie or a huge amount of photos, from internal to external storage, the device would freeze. After it starts up again i notice that i can no longer access my SD card even though the device says it's still mounted. The only way i can fix this is by removing and reinserting the card or rebooting the device. Although there's no problem transferring files from a computer straight to the SD card.
Anybody encountered a problem like this? Is there anyway to fix it?

Yes, I'm having the same issue. Except the SD card will randomly lose the files even though it still shows the card is still mounted. Just recently I was watching a movie from the sd card and this happened.
I am using a SanDisk that was being used in my note 2 for the past year (never had problems with it before).
This is especially frustrating when trying to sync files with Plex.
Anyone have any ides?

Same for me

I know I'll sound like a noob, but my 32gb Samsung micro sd card just doesn't seem to work on galaxy note 10.1 2014, yet it worked perfectly fine on my previous note. Would i have to format the card on my computer? A little bit annoying since I don't have a reader for it.

My Sandisk does not work
I have a SanDisk Ultra 64 GB microSDXC Class 10 UHS-1 Memory Card 30MB/s SDSDQUA-064G-U46A that has a lot of problems working in my GN 10.1-14. It has worked fine for a year in the old Note 10.1. The New Note would not even format it. Formatted it in my Galaxy S4, and it kind of works. Often it simply reports no files, although it will report in Settings the correct size and space available. Sometimes I have to reboot several times for the card to work. then sometimes I will try to open a file and get an I/O error. Then sometimes random reboots, especially if I try to unmount it.

I use a Samsung Pro 64GB microSDXC (UHS-1) Class 10 card (MB-MGCGB/AM) reformatted to FAT32. Works great. I've been using the same type card on my LG Optimus G for almost 8 months 100% problem free (also formatted to FAT32). I did have issues with a SanDisk Ultra 32GB in that same phone that used to dismount itself all the time and I know others that have had issues with SanDisk cards in GoPros as well.

ok, so which one of these sandisk ultra microsd cards will work in the 10.1 2014 edition, and what is the difference between them?

[Q] [Micro SD] Anyone having issues mounting a Lexar 32gb?

Hi guys,
I doubt I'm the only one here.
I got my G4 (h812 LMY47D)and im ecstatic about using my micro sd slot (S6 was the main deal breaker paying top dollars for more storage) but now I'm running into issues with my Class 10 micros sd from Lexar, This darn software does not want to mount the thing (tried several format including a full 40 minute format @ fat 32 default allocation).
The G4 detects an SD card but won't mount it. This thing works flawlessly on my old S3 so it has to be software related as using a cheap Kingston 1gb class 4 works fine.
Anyone else running into issues with their sd card?
Thanks for sharing any info or tips.

Are you sure the g4 does not require different format. Been awhile since i had this issue. Was a format issue for me.

gonna have to give them a call as their user guide states
WARNING Some memory cards may not be fully compatible with the device. Using an incompatible card may damage the device or the memory card, or corrupt the data stored in it.
Not to found about this flagship! having issues reading a descent memory brand when an old rival device of 4 years is capable of doing so...

FIX
Just taught of leaving what got me to sort this out after playing around... Fun times :good:
After tinkering around with another SD card, the LG device formatted it to FAT16.
I've formatted the sd card using http://www.partitionwizard.com/free-partition-manager.html under FAT/Primary
It created a 4gb partition and left it the remaining untouch
Popped the SD on the G4 and it finally mounted the partition
Performed an erase via the phone 2x to make sure and the entire 32gb is now accessible.
Hope that helps others having mounting issues.

I have facing same problems with my 64 GB sandisk sd card on new LG G4
can you explain the procedure to make it work

I've been using an AData 128GB for the last month or so with no problems. I turned the phone on yesterday morning and for whatever reason it went straight to my home screen but locked up and took half a minute or so to unlock and then goes to the lack screen, then I also got a SD Card inserted notification, I figured nothing of it and ignored it. The micro sd runs fine on other devices (formatted as ex-fat) but it causes that issue on startup i mentioned above as long as it's in the phone and it also refuses to mount.

I'm using the SanDisk SDSDQUAN-200G-A4A 200GB ULTRA MICROSDXC UHS-I since 2.5 months ago formatted in exfat with 128k clusters which was what it was out of the package and it works fine.

SanDisk is the only one with something larger than 128GB at this point in time and notice it's 200GB instead of 256GB as size usually doubles in capacity, heard the 56GB was used for something else or maybe not usable. I have a new 200GB card in there now. There is a 512GB card coming soon from Microdia as well.
