Hi,
I have my SD card (class 6) merged with my internal storage. Every app I move to the SD card lags like hell! They work perfect when on the internal storage. My storage is starting to fill though as it's only an 8GB device. Any ideas? I've been thinking that if I get a class 3 uhc SD card (they reckon they're up to 60 MB/s) but I'm not sure is that the problem?
Thanks for your advice.
Class 10 should be bare minimum. I am pretty sure the class 6 card is the cause. Uhs 3 is recommended.

I would concur with @Gravemind2015 your card is too slow... Although I think a minimum UHS1 card is required to make it usable due to the higher write speed than a Class 10, but I do agree a UHS3 is recommended.
A Class 6 card is just too slow for use as adopted storage, I would convert it back to portable until you can get a new card or it will constantly lag on you.
Thank you for your help
I've bought a UHS Class 3 card, installed it and it's solved the problem.

The card reader in the 3rd and 4th generation G devices is UHS-1, it's write speed is limited in real world use is limited to about 45mbps, or about 1/2 to 1/3 of the embedded storage chip... You will always have some lag by comparison. Will a U3 card be better? I can't answer that definitively since it would vary based on your specific usage.

I'm thinking of getting a new SDHC card for my Universal (currently running Tomal's v8.2). I'm leaning towards getting an 8Gb MicrosSD card with adapter for convenience, and obviously have the choice of class 2, 4, or 6 - there's not much price difference.
However, OllieD's SD settings ap mentions Type-I and Type-II, and I don't know what this is. I'm assuming it's nothing to do with the SDHC class?
Should I be ok getting a class 6 card, or are there compatibility issues I should be aware of? I'm likely to purchase the card from eBay, so if somebody has bought a MicroSD that works find from there, then please provide the info of type and seller.
Cheers,
Steve.

Hi Steve,
OllieD actually has coded the UI for me. Thanx to him.
Type-1 is actually the driver in compatibility mode of Class4. You should try first the type-2 driver if it's a Class6 card and select type-1 in case type-2 doesn't work well.
regards
Is it safe to assume that those using class 4 cards should select Type-I?
Just to throw a bit of added confusion into the mix; according to SKTools, my 8Gb class 6 Sandisk MicroSDHC runs about 40% quicker using the Type I setting, than it does using Type II.
Cheers,
Steve.
I've just done some benchmarking with PocketMechanic SD-card benchmark and I must say that my Adata microSDHC 8GB "Turbo" class 6 card (in an SD adapter of course) also works significantly faster with "Type I" set. In some cases it's even 2-3 times faster.
Agreed, this is what I have found. Type-I is faster for my 8GB class 6 card.
My 4GB card was about same speed with any setting.
And my 2GB MMC card was fastest with Type-II.
I tested my card: Kingmax 8GB SDHC class 6
It is 3-6x times faster with the Type I setting.
My V-Gen 4GB SDHC is unstable with type II, need to be re-inserted all the times. but, it very stable with type I.

Yeah, I found the same with my 8G SanDisk Ultra-II. I always select Type-1 now and have never had any problems.
Only thing I would add, if you're playing with ROM's and have to DOC-format the device, make sure your SD card is out and safe somewhere before you start resetting the device into bootloader mode.

Hi
I bought a Kingston 8GB SDHC Class 4 card today, I used a Class 2 before, anyway, I copied a lot of music (about 4GB) to the card from the computer but I don't even get close to 4MB/s only 1.38MB/s, have I done something wrong or is it a problem with the card?
thanks
If you're copying file to your phone over usb it will be capped at 2MB/s. It's the phone's fault, not your card. I bought a 16gb class 6 without knowing this and now I have to take my memory card out if I want to take advantage of the write speeds.

You may have been scammed. To know for sure, you should run the h2testw program against the new card. It's quite common for scammers to pass off 2GB cards as 8, 16, or even 32GBs. They can program the card to tell your PC that they are bigger than they actually are.
The h2testw script can test this by writing 8 1GB files (approximately) to your card.
Good luck!
Hello!
I bought Kingston 16gb class 10 micro sdhc card and I tested it on my nexus one getting result 6mb/s and in unbutu getting same results. Both was directly pluged (Not Usb). I closed every running application in nexus one and I got same result. I also tested in different partitions and in ext2 I was getting little slower result than in fat32. But both were same or under 6mb.
Is there something wrong with the card or is it issue with nexus one that android 2.2 doesnt support class 10?

please include where it was purchased, how much, and if there are any serial numbers/stamps on the card. there are known fakes in circulation (even brick and mortor retailers) fyi.
http://www.verkkokauppa.com/popups/prodinfo.php?id=1244 , bought for 101 euros. Serial in the card: SDC10/16GB N0206-001.AD00lF Taiwan.
ANd on adapter reads CHINA
wow thats really slow i have a 16Gb class 4 and i get 7 ~ 8 mb write speeds when the card is in N1 and connected with usb.
I would assume it's the card because as I and someone else stated above, get higher speeds with a lower class card.
As stated here:
It's my understanding that the "Class" simply refers to speed rating and thus should not effect compatibility. As long as the card supports the microSDHC standard and isn't any larger than 32gb it should work. You should also note however that in the past, vendors have claimed a higher class rating when the card did not actual perform that fast. I suggest buying from a trusted vendor with a good name.
32GB SD Card
Anyone tested the 32GB card, I know it's only class 2....
Android Class 10, SDHC3.0 compliant ?

Class 10 should be supported, but they are usually SDHC3.0 card which is new I think...
I have a kingston class 10 as well, same issue, read speed is good but write speed is rated as 2gb, I tried to change the sector size to 4k and still the same.
For those thinking it's a fake card it is not! when I place the card in an adaptor I do 10MB write and close to 16MB read so this is a class 10.
I am not sure if it's the SDC tester app that is wrong or the phone
but since the phone behave fairly well compared to my class 4 card it could be the application. I will do some internal transfer tomorrow to see how fast they go
me too

Hi guys
i recently received my Sandisk Class 4 16gb micro sd card, but im getting pretty slow speeds with it.
Its currently in FAT32 format.
When transferring files from my computer to the card via the usb cable, im getting 3mbps, which is much slower than what ive seen others get with a class 2 sandisk microsd card.
Also when i test the card using 'SD tools' in the app market it says it should have write 5.7, read 10.4, which is not what im getting and still slower than results ive seen others get with class 2 sandisk microsd cards.
I also have an old 2gb Verbatim card (with no class markings), which is currently in FAT format (not FAT32), that came free with an old phone, that seems very quick when transferring files, much quicker, and in SD Tools it gets - write speed 2mbs, read speed 17 mbps.
Questions -
What format should i set the card to maximize performance (not using app2sd)?
Is a smaller capacity card of the same class faster?
(is a class 4 8gb faster than class 4 16 gb?)
Is FAT faster than FAT32?
Is my card defective?
Should i return it for a class 2 as they seem to be faster?
Hope you can help
For starters, which of those 2 file system is really faster don't matter because you cannot use FAT16 on your 16GB card. FAT16 only supports up to 2GB.
Also, class 4 is suppose to be faster than class 2.
sounds like you got a fake Sandisk Class 4 16gb, a knockoff market imitation with low quality component
what is the actual speed test result of the write?

Thanks for the reply allgamer, I've seen many of your posts on these boards and your very helpful
My actual write speeds are 3mbps, when transferring from my pc to the phone via usb cable.
I got the card from play.com so I didn't expect it to be fake. Are there any other tests I could do to confirm its authenticity?
Should I try different file systems like ext2 or fat etc?
3MB/s for a class 2 card is pretty good. I don't what you can expect more from that.
I have an Kingston 16Gb Class 4 and the writing speed from pc -> phone is like 2MB/s, much slower then it should. But in SD Tools its shows 4 or 4.8 MB/s writing speed.

The card I got is a class 4, and being a san disk I expected better write speeds.
What is really confusing is why the 2gb card (with no class markings) I got free with an old phone is much faster at transferring files via usb despite it getting a much lower score in SD tools.
Can anyone explain that?
Hi,i've bought a micro sd for my nvidia shield k1 (micro sd: class 10; 90 mb\s; toshiba exceria U3; 128gb). I format it like a internal memory and i moved some apps on it.Simple apps like aptoide crashed,some doesn't start and games doesn't load or lag. Why?
The micro sd is: https://www.amazon.it/Toshiba-Sched...=8-1&keywords=toshiba+exceria+micro+sd+128+gb
A U3 is usually good.
Go to the play store and look for A1 SD bench. Then test the speed. Maybe your SD card's write speed is too slow.
I can recommend: Sandisk Extreme 128GB Class 10 SDXC u3

Format as external, eject and test in PC with h2testw.
Now my sd card is ok now (i didn't touch anything).Another problem: when i try to do a record screen on the tablet it says me: no space of archiviation available.But i have mounted like a internal memory and i have now 128 gb of space.Why i can't record?

Thanks man,the results are 11mb\s write and 40mb\s reading.Now the sd card works apparently good
11MB/s write speed is too slow! I've one of those slow cards too and I had to replace it. The current write speed of the Sandisk is over 45MB/s.
I presume your card is too slow for screen recording. I couldn't download and watch videos simultaneously with the slow card. Also, the download speed was quite slow.

I am using the same SDCard currently in mine. Having a few issues with adaptable storage, however runs fine as external.
