What MicroSD Classes Work with the Desire...?

My question was concerning my 16gb Class 6 card (which actually appeared to be corrupt/broke'd anyway)
I asked about compatibly with the Desire...

Thank you for contacting us.
In regards to SD Cards
I can help you with that.
The card that you are trying to use is not compatible with the phone as the class is too high speed for the device to be able to keep up with the speed. I have included a link to a webpage with the sd cards that are compatible with that device.
http://www.expansys.com/a.aspx?i=196001
If you look under the accessory tab then down the bottom is compatible memory.
I trust that this resolves your query, please do not hesitate to contact us again if required.

I'm sure I read some threads about class 10's working fine in the Desire?
The link seems to suggest only a class 2 or a class 4 will work...

I'm using a class 4 without problems so far.
On a dutch board I read a guy was using a class 6 on Starbust so it should be possible I think.

I've just bought a 16gb class 4 Sandisk and the speed tests show it as being quite a bit faster than my class 4 (non Sandisk) 8gb card!

I'm using class 4, working fine

I'm using a 8GB class 6 card with Custom ROM and A2SD with no problem. Been over 6 months now.

A lot of class 10 cards have issues, class 6 seems to be the most reliable thus far. Some people have had good experiences with A-DATA 16gb class 10.

So from user experience - a good Class 6/10 card should work just fine?

For C6 yes.
For C10 Mostly yes... but usually class 10 is not really faster... so save the money.
Just my two cents.

I'm using Transcend 8GB class 6 without any problem. Try to format by gparted or similiar. Are you using it for any other purpose than storing photos, music or etc? For example for data2sd or apps2sd?

I just bought a transcend 16gb class 6, working perfectly so far with no problems.

I bought a 16gb class 6 to use with data2sd but struggled as the card was broken - so i've sent it back and just have the 8gb class 2 that i got with my phone now - and on stock rom again, so it is just photos and music and froyo app2sd at the moment

basically all branded cards will work fine, the thing you shoud be concerned more onthe capacity you are gonna use. It aint worth buying a 16GB sd when u cant fill even half of it with useful stuff

If speed is your thing then get a class 4 or 6 but I had SD mounted as read only with a class 4 8 gig Kingston SD, so I swooped with a buddy of mine for a class 2 SD from a Nokia n95, no problems since then.

[Q] Anyone here use a Class 10 SD card for Android?

I'm looking to upgrade the crummy 1GB SD card in my wife's TP2 to something faster. I was wondering if buying a class 10 card was worth it or if I should just stick with a class 6 or lower. Does the SD slot in the TP2 even support a class 10 card? Would a class 10 card be noticeably faster than a class6?

Not for this project. IIRC Nate said class 4 seems to be the sweet spot, the higher the class the worse it would be running XDandroid, but even some class 4's work better than others. Walmart has 16G class 4 sandisks for around $20, not too bad if you ask me

C10 cards are supported, but some have had issues. I would not recommend a C10 card for Android use. I doubt the phone itself will be any faster...

Cool. Thanks. So get a class 4 then? Is it worth it to get a 16 over a 8GB? My wife doesn't put much on her phone really and she streams all of her music.

Yeah I've got a Patriot 16Gig Class10 SD card that I picked up on sale months ago. I have been running XDAndroid on it since then and haven't noticed any benefit over my old 4gig class 2 card.
Not sure if it's related to running andriod but at first I was having issues with the card corrupting and losing all data on it, having to format it to be usable again. Formatting a few times with the HP tool seems to be helping.
I had a similar issue with my last phone (HTC Hermes) which would only work with good quality (Sandisk) SD cars, and failed with cheap chinese flash memory. The issue was that the phone wasn't able to remount the card properly in winmo when coming out of sleep, and the filesystem would become corrupt pretty quickly with folders disappearing and files having wacky filenames. Sounded like it was more of a hardware issue than anything.

Yea I use a class 4 card. Some have reported oddness with class 6, so it seems like the type of card matters as well... Because others with C6 cards say they work just fine. I've even had some people say C10 cards are fine, but most seem to have issues with C10 cards. Don't get some cheap knockoff, get a name brand.
As for size, that's entirely up to you. You can have up to a 32gb card. 512mb minimum .

I have a Patriot 16GB C10 card here too, but I no longer use it. It was constantly getting corrupted, the kernel logs were filled with I/O error messages. I'm now on a Sandisk 32GB C4 card and no more problems.

Just don't get a C10 card... I think that's what people should take away from this.
Some have said C10 cards are fine, but most say they are not. A few have had issues with C6 cards, but most say those are OK. I've never heard of people complaining about C4 or below cards - hence the reason I recommend anything C4 or less.

c10 sd android
My company name is WinDroidz and all I do is mod android and windows devices... and I have always seen huge performance gains with c10 cards, c2 sucks major, its just the transfer speed the card can move data at and clearly more speed no matter how u look at it with an SD card. Is crucial... I always used patriot c10, or topram and pqi c6 cards for android SD on windows devices and have only seen a posative result.. this is based on my personal experience of Modding more Devices then I can remember.... not from what I read somewhere or was told by someone... SD card data transfer is the slowest method of data transfer of all other common used methods... there are graphs if u Google it that show sdhc c2 cards lined up against other transfer methods like USB, ide, sata etc..... to put in perspective how ridiculously slow SD cards really are, once u see that u will understand why your phones drags ass so much when trying to pull up gallery after cache has been wiped if you have a ton of pics etc.... so if u are having problems with a higher class SD its probly not the SD and is something else you are doing, or maybe the brand as I can only vouch for the ones I've used... (wouldn't care personally about brand as pretty much everything is same manufacturer with restamped brand and packaging.. Kingston is Japan... currently using a c4 Kingston 32gb in my desire HD (wish it was a c10 but kinda pricey for that size and brand) I recommend c10 8gb for $30 on Amazon if u are using some kind of android SD rom.. or any device if u want better transfer speeds and it is very noticeable... no matter what speed u get though it will never run like nand android.. like HD2. So lets just hope the nand development for other devices continues like clk or magldr did for hd2 cause the hd2 with clk and full rom manager support is amazing

16GB class 10
Using 16GB class 10 and have had no problems related to the card, with FRX07.
I personally cannot think of any logical reason why a class 10 card of good quality should ever be a problem.
I just installed and ran Angry Birds Rio. It is slow, but works. Kind of fun to play in slow-mo!

i use 8gb c6 and haven't had any problem so far.

My 16GB RiDATA Class 6 Micro SD has been great, no problems.

may be your memory card carry viruses so try to format it and then format your cell phone also(reset configuration with erase memory card)....may be this could solve your problem...

I see that you guys all use a class 10 card. Is there really a big difference compared to lower class cards?
My phone worked smooth enough with the stock 8GB class 2 card, and my current Transcend class 4 16GB doesn't harm the phone's performance.

class 4 is enough, on phone you will not see any DIFRENCE.
When you connect your phone to PC over USB and conect it to mass storage, you will see then POWER OF CLASS 10. faster uploading to PC, and faster dowloading from PC.
On phone class 10 and class 4 are the SAME.

Well, I noticed a difference and prefer the class 10 all the way.

Hi hi Ok I have a problem and hoping someone can help...
I purchaced a kingston 32GB class 10 memory card and plagued with issues since having it.
My setup is...
Arc LT15
.42 Firmware
Advanced stock kernel
32GB class 10 memory card
Now the problem is images and videos and apps.
Apps...
They keep ramdom uninstalling if they are stored on the memory card
Videos/pictures
Any I have taken since installing the card become corrupted. Even screenshots.
IE I took a screenshot and it displayed on the phone, I went to gallary and viewed it fine.
Came to home screen and back to gallery still fine.
Left some time went to gallary and corrupt.
Cannot be viewed even by PC
This also happened to videos.
I had this problem so installed a totally fresh se rom updated via SEUS (I think)
Cleared dalvik cache and user cache etc manually installed the apps from the card etc etc used no backups apart from contacts backup
Everything was totally clean.
Even my language from swiftkey keyboard app keeps deleting randomly :/
Still getting the issue :/ Is there anything i'm missing?
Thanks,

Hey guys... read cearfully!
The class 10 approx parameters are... Read- 22 mb/s write 10 mb/s
The class 4 are Read 10 mb/s Write 4 mb/s...
So why your phones working bad with class 10?
Because those are linear read-write speeds...and you are using it only while USB connection by moovie transfer or watching... What is the rest card usage?
It is random read-write or seqental read-write used by yor apk's or fo example thumbs of stock gallery.
These speeds are for class 10 - 0.08 mb/s
class 4 - 0.8 mb/s
See the difference now? So class 10 is good for DSLR cameras or mediaplayers etc. Class 4 perfect for phone. Mine 32gb class 4 just flying!!!!!

So your saying 32GB class 10 is not supported fully by the ARC?
Jinx13

I don't get you.
SD speedtest apps give me ~10MB/s write and 20+MB/s read, so it's supported.
Also it feels faster than a class 4 (class 4 vs class 10 was tested in my X10, but Arc is even faster)
Sent from my LT15i using XDA Premium App

It is linear speeds...like you are reading or writing moovie or some one solid big file...
But the system uses random read of small files... And there class 10 looses. On class 4 compared to class 10 in gallery 1000+ photo thumbnails appears in seconds.
Try crystall disc mark software to test your card on PC and you will see. Test config is 5 tests at 100mb...pay attention at 4K and 4Kq32 speeds. At class 10 they are 0.04-0.08...

Ah
Anyways, I'm happy with my 32GB class 10
Sent from my LT15i using XDA Premium App

Ofcourse you are! I just wanted to make it clear for those who says that it is lagy or like that...

But it isn't laggy with the class 10 when you have a good sd card.
The cheap Kingston 16GB class 10 from eBay lagged often in Astro, but no problems with my Patriot 32GB class 10 sd card

So can anyone explain why I might have problems?
From my previous post I just rebooted my phone and lost my SD apps AGAIN!!

Yep! Patriot is one of that card of class 10 that gives you a great performance in any type of R/W. There is a post here, on XDA...there said that patriot is the best card, so my answer is not for you man)))))
About sd apps loss you shold check your app wich provides managment of apps to sd card - links2sd or what it is... the promlem is not in the card.

Or check the sd if it corrupts files.

It is not that program as that program just points to the settings page to move the file.
I have decided to put my 8GB class 2 back in and that is working without problems.

I bought a Kingston 16GB class 10 - Full of problems (returned)
Then a Kingston 32GB class 4 - better results but not that speedy
Now I found for 46euros here in Greece a Samsung 32GB class 10 so I said I have to try this.. and voila! The card is perfect, no lags! The phone is super speedy now!
So I guess it have to do with the cards not the brand.. if you re lucky you will end up with a good card.

Guys, be warned that SGS3 DOES NOT support UHS-1 (i.e. class 10) cards.

There's a thread some on here where the exact card is supported.

does not support, but it works fine if you format the card in the phone. exFAT does not work, however, so you are limited to files < 4gb in size. Kind of defeats the purpose of having such a large microsd card though

UHS1 is simply a speed classification typically used by high power cameras. C10 refers to the minimum write speed of 10mb/s.
This card will work in exfat format for stock GS3, however cwm or twrp recovery only supports fat32 which this card will format to.
I have used this card before so don't be reluctant to to purchase it.

I have been using this exact card since the date I got my GS3 (mid June). It works well with everything and never crashed. It also works with backup and restore within CWM. YMMV though. It is exFAT formatted.

Phone will format it as fat32 and all will be fine. Tested and works well.

What are you guys talking about? Have anyone actually tried this out?
I have this exact same card UHS-1 Class 10 (not the old Class 6 one) in exFat format and everything works fine in CWM and in Android.
EDIT: BTW, I formatted the card with SDFormatter on my PC, not on the phone.

S3 doesn't support UHS-1 speed but it does support exFAT format. The card itself came as exFAT, S3 won't even ask you to reformat it as FAT32. Just pop it in and everything works 100%.

Sweet, just nabbed one. I check the price every day also and was just about to post it here...beaten to the punch as usual .
ps anyone want to buy a Zune80gb heh heh

Is there a good way to utilize an "external" sd card to store apps and nandroids? It seems like the GS3 (and maybe just ICS/JB in general) is setup to use the "internal" sd for everything.

SD formatter is awesome software. I had issues with a 4speed card jumping in my canon. The SDformatter, made it stop. Dunno how it works, but it does.

The card became unusable and I had to fill a claim with Amazon since the seller didn't reply to any of the emails I sent...
Just my experience guys...

Please insert a higher class SD card for the best Zoe experience.

Is what I get when I switch to Zoe mode. What would be the best class of SD card to use? Any manufactures better than others?

If you are having issues with SD Cards, post the format you are using, i.e. exfat, ext3, ntfs, etc... Also, how you formatted it, via laptop, or on the Android device itself.
I have a 64Gb & a 128Gb San Disk SDXC UH-1 & both work excellently. I do not know if it has been fixed, but at one point 64Gb Sd Cards came formatted in exFat, which Android did not support over 32Gb. Maybe they've fixed that, but I don't remember what I formatted to last, it was a few devices ago.

I didn't format it, maybe thats the issue, i just threw it straight in and started using it, I'm in work now and can't check what format it is in, i'll check when i get home.
EDIT: just download an app to check and it is formatted in FAT32.
Whats the recommended format for SD cards with android?

I done the same, but it formatted in HPFS/NTFS and now the sandisk app on see's the card as 10gb, but my computer see's it as the full 64gb, so going to format it back to fat32.
Hopefully someone can come up with a solution.

May be this thread could shed some light on this subject:
http://forum.xda-developers.com/showthread.php?t=1897260
P.S. My SanDisk 64GB card came pre-formatted and I have no issue with Zoe on M8. However, when I purchased SanDIsk Card 64GB from eBay, it showed 4 GB available space? Then I tried a generic Micro SD card 64GB and M8 would not even recognized the card due to poor contacts. I purchased mine from a local Staples and it works w/o any issues. I ended up paying few extra dollars as compare to on-line bargains but it was worth the price. In other words, you may want to try another card and see if it works.
Good Luck

I'll have a look through that thread later. My card is the non mobile sandisk ultra, but its still class 10 uhs-1, so I don't know why there is an issue with it, might contact HTC themselves and see if they can shed any light on it.
