My findings with an AData 32gb UHS-1 card - Vibrant Accessories

My 16 gb PNY class 2 card was getting too small so I decided it was time to upgrade. As far as I could tell the Vibrant doesn't actually support UHS cards, but since I'm only a couple months away I just got one anyway.
I tested the cards with CrystalDiskMark in two ways, via USB in the phone, and in my laptop with an older SD2.0 card reader. The only Android app I could find that did anything other than sequential reads was AndroBench, and I couldn't get it to point at the external card. I'm on ICS, not sure if that was complicating the issue. If anyone knows of an app that does random r/w operations, let me know.
Sorry for the PNY/AData confusion in the screenshots, the UHS-1 card is AData and the Class 2 card is PNY.

Biggest Micro Card?

Whats the biggest micro card this phone will support. Are 32gb / 64gb even made?
i ordered this 16gb one, if there are 32 or 64 i want to know too
Kingston Technology SDC2/16GB 16 GB microSDHC Class 2 Flash Card
At the moment the largest card is 16GB.
16g is the largest, but 32g is coming out soon. My guess is that they will be quite expensive and no word on speed. While the class (speed) is in write mode only, it does make a difference when using the camera or writing files to the card.
I got a Ridata 16gig Class 6 microsd three days ago and works great!

The largest Rhodium supports is 32GB.
SDHC specs out at 32GB max.
I think only a few companies make 16GB Class 6 cards. Transcend being one of them. I don't think you can get 32GB ones just as yet and no way you can get a Class 6 one anyway.

and i think before they release 32gb SDHC they'll go the SDXC way with 64 & 128gb model.
if you plan on getting a Transcend card for use with a GSM TP2, be careful. There have been reports of Transcend cards not working well with the TP2. I personally experienced it, when my Class 6 8GB card would randomly disappear from the phone, or when music would skip during playback. Switched to a Sandisk Class 2 8GB that came with my BB Storm, and haven't experienced a single problem.
And also, note that the Transcend card worked great in my BB Storm, BB Bold 9700, LG Incite and Samsung BJII before this. Nothing wrong with the card, just with the TP2.
16gb is the largest built. 32gb is the largest theoretical that sdhc supports. youll need sdxc for more than that. i wonder if rhodium will support this in the future. old htc devices (and samsung) that could only do regular sd that capped at 4gb could do sdhc with a rom/driver update. sdxc supports up to 2tb which will be interesting to see.
The 32g microsd is long over due. Every so often there will be a press release that the 32 will be release within the next month or so. The projected time frame will come and go. There was a PR stating that 64g was in the works.
if a 32gb microsd card is sold i will buy it. i have an 8gb and could get a 16gb surprisingly cheap but i wont buy a stop gap knowing a 32 might be out soon.
I just got my 16gb no name cheapie from hong kong micro sd card for my tp2 in the mail. I spent numerous hours setting it up with the programs I wanted on it music and such. I had used it for about an hour or so and all the sudden the phone went crazy.. somehow the card corrupted it self im guessing cause the phone no longer recognized it or anything on it.. I removed the card and put it in my card reader to my laptop nothing was on it but a mess of folders all with the name ".." I thought maybe I had done something wrong so I formatted it and tried again. same thing happened the next day. I now reverted back to my 8gb sandisk and havent had any problems with it.. I guess its a get what you pay for kinda deal. Maybe there is something I can do I would think flash memory is flash memory but I guess they have their diffrences. Just wanted to share my .02 on my experience I would like to get another 16gb because bigger is better but ill wait it out and see what is to come next.

Samsung Focus 16GB Class 10 MicroSD

I just wanted to give everyone a heads up. I just bought a Samsung Focus this morning and love the device. The only issue i am having is that it will not detect my class 10 16GB microSD card. I have other 8GB cards and they detect fine but i cannot get the 16GB to work. I have tried the 16GB in other devices (laptop, HTC Hero) and it detects and works fine. So i dont know if it is a size issue or the fact that its a class 10 card but my windows phone will not detect that it is installed.
If anyone has had success with a similar card please let me know.

Are you doing a hard reset on the device after you put the card in?
I have been able to reproduce the same results with a Class 10 MicroSD from Kingston. It is not recognized by the phone with or without performing a hard reset. A class 4 32gb card was recognized with no issues.
Hmmm, class 4 works but not 10??? Class 10 == too fast for Wp7
One more data point. I am also experiencing an issue with the Kingston 16GB class 10 microSD card in a Samsung Focus. Slightly different issue though -- only 8 of the 16GB are recognized.
As you may have seen, AT&T employees are now warning customers to not install microSD cards until MSFT issues a patch. When I bought my Focus this morning, the AT&T salesman brought his manager out to tell me about the problem.
CHANGED: The Transcend 16GB Class 6 card does not work per se. Will see it all 16GB after hard reset, then after turning phone off then on again only sees 8GB of the card.
My A-Data 16GB class 6 card works.
I posted earlier that my Kingston 16GB class 10 card didn't work in the Foucs. I just bought a Sandisk 16GB class 2 microSDHC card, which worked fine. From what I've seen there is no authoritative way to predict which cards will work. However, I have not seen any reports of Sandisk cards failing.
Class 10 cards will not work til update.

it is the class not brand class 10 cards will not work til the update..
Another data point -- I saw instability even with a card that appeared to be working. I first posted that my Kingston 16GB class 10 card didn't work (only 8GB recognized). I then posted that my Sandisk class 2 16GB card worked. However over the next two days, I experienced surprising instability e.g. the phone rebooting itself several times per day. For the last two days I have been running without a microSD card and the spontaneous reboots have gone away. Other people may be having better experiences with their cards. But for the moment, I'll live with less sync'ed music to get better stability. If the spontaneous reboots come back, I'll post again.

You might want to try this card tester on your cards as they mey be bad...
It seems most cards class 6 and above don't work and class 4 is the most reliable. Ho hum!
For what its worth I've been using a Kingston 32GB Micro SDHC Flash Card Model SDC4/32GBSP since Monday and having no problems whatsoever.
Class and size has nothing to do eith it. Google for more info.
Sent from my SGH-T959 using XDA App
The reason Class 10 cards don't work and Class 2 cards do is because of the random read/write speeds. Class 10 cards promise fast SUSTAINED write speed but at the expense of random read/write. Windows phone 7 relies mainly on random read/write speeds to function smoothly. Fortunately, this means that Class 2 cards work very well! I would consider this to be a good thing however because Class 2 cards are cheaper!
Adding to this old dead thread, but was hoping to know if anybody knew if Microsoft fixed this issue yet. I just ordered an A-Data 16GB Class 10 MicroSD recently..
From a quick search, it seems it hasn't though?
Yeah, I don't think anyone has really had an issue with a card since nodo. As stated in this thread however, many people have (in the past at least) had better luck with class 2 than any other class. I've been using the sd card below for a couple of months with no issue with about 30gb of music loaded on it.

Whats the best Memory card for S3

I just got my S3 (United States) and and tried 3 (YES 3) Lexar 32 GB Class 10 cards and every one of them have failed. I called Lexar, they say to have my firmware upgraded. Went to Sprint and verified everything is fine with the phone. The cards won't work in other phones at Sprint Either. Before buying another card I'd like to know from you guys which one out there will work with no problems, speed, and size is important for me. I know I'll be using more memory than the 32gb in the future. I called Sandisk and they recommended their SDSDQUA-032G Ultra 32 Class 10 and said it would work. Sprint says they know the Class 6 works in the S3.
I'd like more than 32gb. and fast write & Read speeds.
Can I get some great recommendations from you before I buy another piece of crap. Two weeks now and I still don't have a working card. Lucky I have Amazon prime membership.

I use a 32gb Sandisk Class 10 SDHC Card, this thing works. Problem with anything bigger then 32gb is that you have to use sdxc and this is only really compatible in fat32 or exfat, for both you have to format the card before inserting into the phone.
Try the SanDisk 32gb Mobile Ultra UHS-1 because it's cheaper than normal class 10 Mobile Ultra and just as fast, and I've been using it a while with no problems.
I am quite happy with my Sandisk Ultra 64GB SDXC. No issues at all.
What do I need to format

I would like the larger size. What would I need to format the bigger size. I wouldn't have a problem with that if I had some detailed instructions.
Thanks.
Sandisc Ultra 64gb micro sd xc1
Sandisc Ultra 64gb micro sd xc1 was my choice and its worked well over the last 4 years. Its the phone that has bricked after Little use in October 27/2016. Changed the battery it needed it. Now its bricked.
I have a SanDisk but I was told that SanDisk aren't good for Samsung S3's
Hello,
I'd recommend the Toshiba Exceria memory card, either with 16, 32 or 64GB. This card is a class 10 card with UHS 3. Although the S3 can't use the full speed of the micro SD, this is a well working combination.
Has anyone tried 128gb sdcard ?
I plan to buy,

I'm using a 128gb card from lexar on it and works fine..
(mine's the i747m just to clear it up...)
I have the SanDisk 64GB ultra sdxc or whatever it's called. It works very well with no issues and I have 1,000+ pictures stored on it with about 30 videos.
Quick question. Would a SD card and adoptable storage on a ROM be a good solution for the Samsung device?
Yes, a SD card is always good, especially for backups

My SIII keeps frying my SD cards!

I dunno if I've just had a run of bad luck with external SD cards, but in two months I've lost 2 SD cards! One 32G Sandisk, and just today another Lexar 8G (cuz I couldn't afford another 32G).
But it just frys them to the point where they just don't read anymore. I even try putting them in a card reader in my PC, and no dice. All my pics, music files, nandroids gone. Stuff that I unfortunately didn't back up on my pc. (Kicking myself hard)
My question is, has anybody else been losing SD cards? And, is there a program or a method that could possibly salvage any of the files on them despite them not being read by any card reader?
Any help much appreciated. Thx

I had a 32GB Sandisk microSDHC class 10 konk out less than a month and chucked it to a bad card. Sandisk replaced it. Prior to that I had a 16 GB in it for months and those were fine.
I think in your case it's just the cards going bad. I think the Sandisk 32 GB microSDHC might just have a bad batch somewhere. I got it from Amazon.com.
Yeah I think you have a bad card also
I use a 32 gig class 10 on my evo shift and the S3 shoots it out of the water, and I've never had any problems with the sdcard on my shift

microSD speed 4 Tab S

what is the speed of Tab S card slot?
I'm going to buy a microSD card and I don't know what speed should I take:
30, 50, 80 or 90 MB/s?
I don't care how fast I can copy files from PC. I just wonder what is the maximum speed of read/write by Tab S?
I dont unfortunatley have technical speeds of how quick it copies but i found that mine. Could happily copy 2GB files from internal to my UHS1 64GB sd card from samsung pretty quickly, within 1 minute.
So it is about 33MB/s. Class 10 is not enough.
So minimum Sandisk extreme?
http://www.sandisk.com/products/memory-cards/microsd/
I guess depends if you can get a UHS-2 or 3 that a tab s can make the most of? Just used A1 SD Bench and got 30 MB/s write and 13MB/s read (edit. Other way round). It is a UHS-1 samsung micro sd card. Possibly a samsung EVO or SanDisk extreme.
I have the Lexar 64gb 600x micro sdxc class 10 UHS-I 90mb/s, I have had it about 4 months now and it was previously in my Samsung Galaxy S4. I have never met transfer speeds as fast on any other microsd I have used before, nor have I been met with such stability. I have one of these cards in my Samsung Galaxy Tab S for storing any media (books, music and movies) and haven't had any issues still. I also have another in my Samsung Galaxy Note 4 I which I play music from every single day.
As I said, I have had the card for a few months now, and I have used it in 3 different devices, all with outstanding performance. The origin SanDisk microsd cards I purchase (2x 32Gb micro sdhc ultra) I had to return 3 times before I had a reasonably stable working product. I am not dissing SanDisk nor promoting Lexar. I just want to share the experiences I have had recently.
I hope this helps. Message me if anyone has a question.

Can you make a speed test in A1 SD Bench and post results (Tab S)?
A1 SD test results.
The first picture is the test results from my lexar 64gb sdxc 600x UHS-I
The second picture is a comparison using SanDisk Ultra 32gb sdhc.
Testing device is the Samsung Galaxy Tab S (SM-T700).
