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

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!
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?
I picked up the Moto G 4g LTE version recently hopping on the fact that they added an sd card slot. Anyway, I purchased this http://www.amazon.com/SanDisk-Ultra-MicroSDHC-Memory-Adapter/dp/B007XZM6VG/
microsd card hoping for some nice expansion. But for some reason whenever I insert it it says damaged sd card, tries to format it, then says blank sd card, and basically loops this process. Now here's the weird thing, this sd card works fine (can read and write) in other people's phones, but just doesnt seem to work in mine!
I even tried my friends 32 gb microsd card and it worked (it was a slower class 6 varient),I tried *my* sd card in that persons phone, and it mounted and worked fine, the sd card works in my PC also.
I'm wondering if I need a slower speed card? Maybe class 6 or 4. Because I read up on another guys problem on here, his is freezing but he got a slower 32 gig card and now it works without a problem. I know he was having a different problem but I'm wondering if the phone is having an issue with class 10 cards.
Anyone having the same problem or have any idea what might be going on?

Hi,
As I mentioned on the "other guy"'s topic, I experienced this kind of issues with my previous phone, which were entirely solved by replacing my 32 GB Sandisk class 10 card with a 16 GB Samsung class 6 card. AFAIK, fast cards may cause malfunctions with some Android phones, because of the access response times.

Had the same issue. resolved by getting a different brand and lower class. all issues resolved.
I'm using this card bought thru Amazon for 17.99 ------Samsung Electronics 32GB EVO Micro SDHC with Adapter Upto 48MB/s Class 10 Memory Card (MB-MP32DA/AM)------
I have had 0 problems with it and high benchmarks, I use to use Sandisk but after multiple problems with multiple cards over they years I have completely abandoned them for Samsung and have yet to have a problem.
The problem comes from that, some cards won't fall back to lower performance level and thus causing issues for the device that it is inserted in.
Some devices does not have problem with that tough.
Another reason could be the file system used, but that's less likely, although not very rare.
And one more thing is that brands like SanDisk, Samsung, Kingston etc are the actual developers of the SD technologies and sometimes you may get a product that is using newer technologies, which often causes troubles.
I purchased same Sandisk micro card from Amazon as OP did. I got same results. It is sitting here on my bed with RMA on it to back to Sandisk. Just got a new speck sheet which was posted from the motorola forms that says the following:
Micro SD UHS-1 "The card will work, BUT the Moto G 4F/Lte WILL NOT SUPPORT UHS 1 - SPEEDS.
So it appears, a slower speed card is in order. I just had to purchase a Samsung 16 gb class 6 card. Would rather have had a 32 gb but could not find in class 6.
Random and Sequential of my 32gb Samsung Evo UHS-1 in my Moto G LTE using A1 SD Bench
Thanks so much for the input and advice guys! I was too impatient to order another sd card and wait for it to ship so I went and bought a random 32 gig class 10 card from a brand i've never heard of called "Monster digital" and it works perfectly. So I'm not sure what really fixes it, if it's a brand thing or size or speed or what. But my change from my non working sd card was Speed: UHS-1 -> Class 10, and Brand: Sandisk -> Monster Digital
Regarding the SD card issue. I tried with three separate phones with a 32gb class 10 and and a 16gb class 4 -- failed on two of them, but works fine on one of the phones. So there is definitely a build quality issue ( and/or difference ) between the phones, aside from the mentioned 'supported sd card class.' Both of these cards work fine on all other devices ( pc/laptop/tablets including old SD card readers with adapters )

Wanted to give an update. Tested with four devices now ( 2 black, 2 white ) and First one ( white ) worked, next two did not work, but the fourth device ( black ) it worked to detect 32gb sandisk without fail. So there is _definitely_ a difference between them from device to device -- maybe even assembly line quality control issues depending on week of manufacture, who knows.
Very interesting (and puzzling). Do they all run exactly the same version of Android? Are they all exactly the same model (eg. XT1032) and the same internal storage capacity (8/16 GB)?

Oops, Moto G LTE is 8 GB only, sorry.
Yes.. exact same model/capacity and OS, all ordered within the same 1 week period ( two being RMA )
Can verify that the XT1045 4G LTE performs very well with a 64GB SDCard inserted internally, ALSO..with a 32GB MicroSD card inserted into the USB / Charge port..and runs both very well, and with both cards mounted..

I have a Moto G LTE on order, and am wondering if the various problems people are seeing are due to the file system used on the card: exFAT or FAT32. I would assume the newer SanDisk cards are formatted with exFAT. Does the flavor of Android on the phone support exFAT ?
Another issue I've found in the past with some other devices and ROM's is that if the card is formatted as exFAT, it might need be set up as a primary partition and not a logical drive (using MiniTool or some such).
But we'll see what happens when the phone & card actually arrive
As far as I'm concerned, my cards were all FAT32-formatted, both the malfunctioning SanDisk and the Samsung that worked well. Nothing to do with exFAT vs. FAT32 then.

Exact same 2 cards ( check my previous post ) , tested on 4 (four) MOTO G LTE , 2 Samsung and a Camera and a Tablet worked only on 2 of the MOTO G LTE's + all the other non motorola devices. It cannot be the formatting or even the make of the card if it's a compatiblity issue.

Try a slower card (class 6 fort instance).

Just got my moto G 4g delivered today and My 32gb Sandisk Ultra (which I had for 2 years in 6 different phones) won't work. looked it up, saw this thread and I'm kinda sad that I have to buy a new sd card for this when I paid a premium to have the ability to use a sd card in the first place. Nonetheless, I'll take the safer route you guys talked about and try for a lower class speed. Just ordered a samsung 32gb (not the evo model) class 6 from amazon for about 19.25 after tax. it should be here on the 25th I'll let you guys know if it's a good one to use. I knew kit kat didn't play nice with sd cards but this is ridiculous.
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.
Broadcasted from Zeta Reticuli
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.
