I bought this card from Amazon: http://www.amazon.com/Transcend-mic...YX8U/ref=sr_1_5?ie=UTF8&qid=1322469285&sr=8-5
Although I've noticed my write speeds when transferring 700mb-4gb type files only to be 2.32MB/sec. Reviews on amazon show that others are getting 4MB/sec...
no... but i saw this browsing the web... http://www.adorama.com/IDSMICSD32G.html?utm_source=ET&utm_medium=TransactionalEmail&utm_campaign=2point0Product1 its cheaper...and the site has great reviews...
I have the same card and my speed is around 4.2MB s. Have you try testing the speed of your card on a PC?
You can also try to format the card in the PC. I've seen it helped with my other micro sd card for the Motorola Photon.

how should i format it, in FAT32? i formatted it with the phone after i got the card.
i also notice that if i transfer files while in clockwork mod recovery, it'll transfer at 3.5-4MB/sec, but back to only 2.35MB/sec when booted up.
Yeah just format it to fat32. You can also try "sd formatter" program for windows.
Have you tried the Android app "sd card tester" to test the card speed? Do that test first to see if the problem is indeed with the micro sd card.
From my experiences with micro SDHC in the Nook Color, there is no substitute for SanDisk cards. Their class 4 card is faster than everyone else's class 10s.

Just to clarify this fact, as it depends what you use the SD card for.
If you are running an Operating System from the SD card Sandisk have been found to have very fast random read/write speeds, but if you're recording video etc a Class 10 is better. The reason is an OS needs to write and read data from all over the card but recording video writes sequentially.
If you're not running the OS from the card, a higher class of any quality brand card will serve you better. If you are running the OS from the card, like many of us are with our Nook Colors (and lovin it), get a Sandisk Class 4.

Hi all
I have had a SanDisk 4gb microSD HC card for ages and it's worked perfectly. I recently bought a SanDisk 8gb one and have a permanent problem with it. When inserting it, sometimes my TP2 either fails to recognise it or if it does, sometimes it freezes some functions. The main problem is that the clock completely freezes. Unfortunately, it doesn't happen every time.
I put the card into a Card Reader on my laptop and ran a CHKDSK on it and it came up as OK.
Has anyone encountered the same problem or any solutions as to how to fix it. If I go back to the 4gb, it works fine so it's not the slot or device but doesn't look like the card either. I can copy stuff with my laptop over and back to the card no problem.

I have a SanDisk 8GB Class 2 SDHC card, and have no problems with it.
Try doing a full format on the card to see if that helps after copying all your files off it.
In addition to that, reflash your phone with a Stock ROM and then flash it with the current ROM you are using. Do this without having any card in the phone.
Also, If you have a can of compressed air lying around, use the nozzle tip and blow into the microSD card slot of the phone to try and clean it out.
Hopefully this helps.
No problems here. I started with a Sandisk 8GB Class 4 microSDHC and now have a Sandisk 16GB Class 2, and haven't had any problems with either one. I'd try a full re-format of the card and see if that helps.
I started with the Vodafone Stock ROM before changing for Deepshining v12. Could a ROM version cause issues or maybe the Radio ver ?
And how can I tell what Class my SDHC card is ?
C
i use a 8gb sd card.. no problems with it..
My 8GB Class 4 SanDisk MicroSDHC works perfectly. Sounds like you have a faulty or counterfeit card.
I'm using an 8gb class 4 Dane Elec (sp?) micro sd, and it works fine.
To see what class it is, look at the card. Does it have a circle with a number inside of it? It will either be 2, 4, or 6. If there is no circle with a number it's most likely a class 2.
I had the same problem which i actually solved by backing up the card and choosing to format it via my PC, check it out too.
I did a full format of the card using FAT32 but still no different. My card is a Class 2. My understanding of counterfeit cards was that they could only store a fraction of the supposed total whereas I can fit 8gb on this.
C
I started with a 1gb class 4, then 8gb class 2.
now im using 16gb class 2.
Ive never had any problems with any of them.
Sounds like a problem with the card.
You could buy another 8gb and try that one. But you'd have to fork out more money just to see if it is the card.
Best i can suggest im afraid
Hi all again,
I've tried the 8gb card now in a HTC Kaiser (never knew it could take an 8gb) and it works perfectly. Therefore, it must be something with my Touch Pro2. So would it be the ROM or the Radio which could potentially screw up access to the 8gb card ?

Well, I just bought an 8 Gig Class 6 Ridata Lightning microsdhc card...that got pretty good reviews, actually... and which also tests out to be a Class 6 card on SD Card Speed Test. The huge problem, for me, is that when I plug the card into my card reader on my pc, which is rather new..., I get TERRIBLE transfer speeds...even slower than any Class 2 that I've used. Any ideas? Should I request a replacement even though it's testing out as a Class 6? Is it my card reader? Is there any requirement for an internal card reader to read sdhc cards? Anyone with any insight would be very much appreciated. Thanks!

It might be your card reader/computer. On my Class 4 I get speeds that surpass the transfer regular speed. If you have a sd card reader in your laptop/desktop try updating the drivers. If the reader goes into the usb slot, then get a new reader, or try out a different computer...This will help isolate the problem and your headaches.
Thanks, bro...

Yeah, thanks, I'll try finding drivers for it, there's an ! in device manager under USB...so I'll try to get it to recognize the hub drivers.
I bought a 32g microsd class10,but the problem is when i try to pass all my files from my other microsd,there a missing files like clockworkmode,and i cant open some of my pictures,i put the micro sd in my inc2 and download the clockworkmode from alpharef or rom manager and i can see the file but incomplet also if i try to pass my stock rom i can see the process but whn i open the clockworkmode and look in the save file there not any stock rom in there,if try to go in to recovery mode dont let me jist reboot and i have to select reboot.if ltry to save my current rom using rom manager its look like is doing something but the download bar dont do nothing,and then i check the saved rom and its in the file but imcomplite i dont know what to do with....thanks...
What is the brand on the card? It may look good, at 32gb class 10, but if its not from a decent manufacturer it may not be worth the small price you paid.
Personally, I stick with pny or sandisk.

I bought another microsd 32g class 10, But this one is PNY and work great i dont have any issue transfering my files.I boughted in Newegg.
Thanks for the FYI on Pny.
I know they are a cheaper brand(price-wise) so I tended to avoid them for more name-brands.
is it a simple COPY > PASTE affair to upgrade to a new card?
i read in the past that other phones used the sd card for swap and such, which needed different procedures to upgrade but the Inc2 doesn't have any of that dependency
i picked up a 32GB Class 4 Sandisk card which should be arriving tomorrow. Hope the upgrade goes as smooth as yours
ps. you should do some benchmarks of your pny class 10 vs the OEM card. as i understand it, the sd controller in our phones aren't rated for class 10 speeds, which is why i didn't bite on the faster (more expensive) class 10 card. it would be interesting to see a comparison though.
you can use something like AnTuTu Benchmark or SD Tools. both available from the market.

This. a class 10 is kinda pointless for a phone. i remember reading somewhere on here about how any card above a class 6 will slow the phone down.
Also that off brand sd card was probably not a 32gb nor a class 10.
I bought something similar off ebay a while back and it ended up being a card that was labeled 32gb class 10 but the benchmark stated it was a 200mb class 2 or something like that. They take these already labeled 32gb class 10 cards which failed the test off the line and resell them as such although they are not.
glad you got your money back
i used AnTuTu Benchmark with the OEM 16gb class 4 card.
read: 4.4 MB/s
write: 16.6 MB/s
the Sandisk 32GB Class 4 card I picked up, according to the reviews, have above-standard write speeds for a Class 4 (something like 5-6MB/s). i'll post up scores when it gets in but i would suggest this one just for it's brand name and consistent reviews

Buy that card from Taobao?
hey guys. i have been trying to migrate over to the 32GB sandisk card without luck. the file transfers over just fine but my phone can't identify where the apps are (the card is recognized in the phone, including the full capacity).
i'm trying to resolve this before doing the benchmark. any help is appreciated!
Ps: i just copy>pasted from the old card to the new card. nothing fancy and no errors. and yes i do use App2SD

I think,the problem is the sd card, i had problem before with the first 32g sd card but when i purchase a 32g pny sd card class 10..i could swipe everything whit no problems.
I got a Samsung 32 GB Class 10 microsd card today and formatted the it into NTFS in Windows 7, and copied a big file, the speed met the nominal value about 13 MB/s. But I found out later that android does not recognize NTFS format. Therefore I reformatted the card into FAT32 in Galaxy S2. But when I copied the same file into the card under Windows 7, the writing speed decreases to about 5 MB/s. Later I used the app called "SD Card Speed Tester" to test the speed, it told me the card is a Class 6 card!!!
Is there anyone having the same problem? The only solution I can come up with is to format the sd card into ext2 and try again. Can anyone tell me how to do it with the phone, is there an app for that?
Thank you in advance!
I'm sorry to be the one telling you this but you might gotten a fake one...Where did you buy your sd card?
I bought it from a German company. Nevertheless, I just test the card (still with FAT32) with the original SD adapter under Windows 7, the writing speed is about 10MB/s, which is more close to the nominal value. So I think it is the problem between GS2 and the card.
Any idea to format the card with ex2 by GS2?

You should see better performance with NTFS, that is normal. Still, your speeds are unusually low.

Finally, I test the card with adapter under Windows 7 on my laptop using h2testw for NTFS and FAT32 format, both of them have the same performance, about 10 MB/s for writing. And I also inserted the card with FAT32 format in milestone, the writing speed is still about 5 MB/s, I did not test with NTFS format.
The card costs me 30 euro, and it functions normally with adapter, so I don't bother to return it. However, I am warning you guys, do not buy SAMSUNG 32 GB Class10 sd card, it can only achieve around 5 MB/s with FAT32 format.
Derp.
If you can fill the card it's not a fake, the only problem here is your expectations from the i9100's sd card reader.
I bought a new Sandisk Micro SDHC 32GB UHS1 to increase a write/read speed to/from sd-card. But the problem is the sd-card steadily unmounted when I listen to the music or watch the movies. I think it‘s because of the class of the sd-card.
Can anyone confirm that this doesn‘t happen with the other class of the sd-card (with the same capacity of 32GB)?
I‘ll be very grateful for this.

I have a 32gb class 4 SanDisk MicroSD HC card, and I've actually never had any card issues at all, ie unmounting, corrupting, or anything weird. I've seen higher class 32gb cards, but I know how rare it is to have a microSD that doesn't ever give you any problems, so I'm sticking with my slower class 4 that has never let me down since I started using it about 5 months ago.
Well, I found the problem. Our devices are compatible only with microSD cards that have 2.0 interface like classes 2-10. UHS1 cards have a new 3.01 interface, therefore our devices don‘t support the new interface.

It's supposed to be backward compatible, but I guess things don't always work how they are supposed to.

I agree. With my Sandisk 32gb (Class 4), I formatted it as FAT32 with 64kb clusters from a card-reader on my PC.
I had unmounting issues as well, but I believe I incorrectly disabled something when I was debloating my Nitro...Once I started using CM9 though, the unmounting issues went away.
* If your Nitro is stock, then I would suggest trying to format your card from a PC and trying again.
* If you're rooted, stock rom and did some debloating yourself...Try getting your phone back to stock and see if you still have issues
* If you're rooted and would like to try a new ROM, definitely try CM9, that will take care of the bloat and potentially the unmounting issues.
Hmmmm I just bought a UHS-1 card, haven't opened it yet. Is this phone for sure unable to take advantage of it?

Try heading to http://www.sdcard.org and download the SD Card formatter. Format the card and see if it makes a difference (Needs to be done from a Laptop/PC). I know I had to do this with one of my external SD Cards and it started working again, but I did not have the same problem as you.
