Anyone using the Transcend 32GB Class 4 MicroSD card?

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.

32g microsd

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

Did you unmount the old on from your phone, stick the new one in and format the new one first?

Micro Sd card reader: Any reviews for a fair priced fast one?

Has anyone found a inexpensive yet fast Micro Sd card reader?
I just got a Sandisk 64GB and would love to find something that could reader and transfer files to it as quick as possible. I looked at DX.com but a few units mentioned slow speeds. Anyone have any they can vouch for?

I have a Sandisk 64GB and several reader/transfer USB devices. All of them tell me the SD needs to be formatted. My SGS3 accepts media file transfers on the card though. All my readers can read my 32GB SD cards and transfer files with no problems at all. How are you getting files (other than media) to transfer between your PC and 64GB SD card at any speed, even slow?
* * *
Figured it out after reading more SD card posts...
My XP laptop needed an MS update to read exfat. Got it and everything works now.

I got this one from Amazon when it was on sale for $28 as the lightning deal of the day.
http://www.amazon.com/gp/product/B00A4A1TYM/
It comes with a USB 3.0 SuperSpeed microSD card reader (that just sweetened the deal) best of all, this card is rated a UHS I class 300x
I would have gone with 64GB but I'm glad I didn't since you have to hack your ROM to use it as your internal storage on Samsung devices. This is one thing HTC does right atleast. They let you combine your storage, why can't Samsung do the same...
the speeds are very impressive though, it outperforms my Class 10 8gb microSD
I get 41 MB/s read and 24 MB/s write (with the USB 3.0 jack)
with USB 2.0 it cuts those speeds down in half

[Q] 16GB Class 10 Micro SDHC, only 2MB/s write speed

So I have this SanDisk Ultra 16GB Class 10 microSDHC Card from Best Buy, which was on sale for $20 when I bought it two months ago. Formatted the card as soon as I put it inside the phone. I started to transfer some music albums from my PC and the write speeds are very slow, averaging only 1.8 MB/s. I'm not getting anywhere near Class 10 write speeds. Don't have a USB SD card reader that supports SDHC, so I don't have the option to take it out and use the SD adapter. I tried using an SD speed increase app and changed the cache to 2048 KB, but same result. Didn't want to bring up this issue until now.
Anyone have any solutions to this? If it helps, I'm running CM 10.1 (Android 4.2.1), Nitest 12-31 kernel for CM 10.1 Preview Build.

Makes a huge difference because you will need a usb 3.0 port on your computer for that to work

I don't think so. My Transcend 4GB C10 and Lexar 16GB C10 are writing at 10MB/s just fine on USB 2.0 reader and ports.

My Take...
1.Transferring multiple small files will always be slower in transferring speed than a single big file.
2. Using your phone as an alternative to sd card reader will be a lot slower at transferring files to your PC. I always prefer to take out the memory card out of my phone and connect it with an sd card reader instead of attaching a direct usb cable to my phone.
3. install "SD Card Tester" from the play store, try to close all the other open apps and test your memory card with it within your phone. My results with my Micro Center branded class 10 card were ~6MB for Writing and ~7MB for reading of 348MB test file... I'm sure though if I test it again with my PC it would meet the advertised 10MB writing speed.

When connecting the device via USB cable, don't expect the transfer speeds to be that great. MTP is the default transfer protocol if you didn't change it. If you need to move files off of your MicroSD card quickly, its best to remove the media card from the Note 2 and put it into a card reader. As for the gallery app on the device, from what I have experienced is if you are using the card for the first few times it may take some time for the picture thumb nails to enumerate completely, especially when you have a lot of photos/videos.
This is purely from experience. I hope this helps a bit.
