Well, I have two microSD's.
1- Fake microSDHC & unknown class 8GB, : > worked only cotulla's system but too slow (the newer devs version doesn't work) it needed two hours for first boot, and the second time half hour. the newer devs versions will add about ~20MB Data and will stop. but cotulla's continues to complete the process witch means android boots and works, but slow.
2- Genuine, Transcend Class 10 8GB, : > Very Perfect! too Fast speed!, powerful... needs about ~1 minute or less first boot, & second time about ~10 Seconds! amazing!
I Very Recommended to buy the Transcend Class 10 once... it's very perfect very speed! also cheap, on amazon about $15.
microSDHC Transcend Class 10 8GB ***** 5 Stars for boot Android
yes.nwo i will list the cards that i used.
1.all kingston 's tf card is ok. all can successfully get into the system. the entering time depends on your card's speed. class2 is the slowest,but can be used.
2.most of Sandisk's cards cannot be used. althought you can format it by using the tools, it cannot get into the system. the mistake is that the memory module is different from the others. but Sandisk 's speed is faster than other cards,which have same class speed.
3.samsung and toshiba all OK, can fluently use, just class2 is also fast like class6...
4.some of the none name card can be used, like nokia's normal card,some cards that is given when you buy you mobile phone.
sorry for my poor english..

Indeed, Class 10 Transcend is very good. However, I still have to manage android boot optimization because a lot of installed apps are slowing the start-up process, even with the class 10 µSD...

Of course, that's right!
but about slow start-up process, second time is ok even restart android. but I could know why shouldn't first time be ok? also... it's not brand's problem.. maybe because SDHC are like that... or NAND?
thanks!
i just ordered the TS8GUSDHC10 on amazon for 13euros, will let you know if it works good
I have two of them, both working pretty good: 13M/s write and 18M/s read

Strontium 8Gb works
I have a Strontium 8Gb HC card don't know other details but it works even with winmo folders.
Only all the android files should be in root.
Nice, now you can install (if you want) this app: SD Tools on HD Mini to see details of your card
and this on PC, to measure the speed Crystal bench mark (Portable Edition (zip) for Windows
Here's Manual
So if you have 2 or 3 cards, with this you can measure and compare and know what is better for you
Note that Random Write 4KB (QD = 1) is the most important when it comes to Android port (wich boot and runs on the Micro SD card)
installed SD Tools and these are the results
Manufacturer SD08G
Write speed 5.3MB/s
Read speed 14.3MB/s
Class ?
I tried installing android on 3 cards that i have, but failed.
The cards i used are:
-sandisk 2gb, the one that comes with the phone. (It is reported not to work so i dint care)
-no name 2gb sd card (no class info, but it seems to be class 2) which was provided stock with a nokia phone. I expected this to work since mooncmn had reported it working in the earlier thread.
-transcend 4gb class 2 card
I have formated all cards in sd formatter with full overwite and format adjustment off and then format fat32 on winxp and then i copy the files into phone. All this i do in "disk drive" mode. Then i remove the usb cable and load haret.
I tried out several versions of android as well:
-googlecode : I tried it multiple times on all 3 cards waiting minimum for 10 and upto an hr. When i reboot to wm i can see data.ext has stopped at 30mb on all cards irrespective of the time i let it load.
-munjeni and cm6 : both had the same problem as above, it stops at 30mb which is strange. in munjeni's version it stops at a point which i have attached the pic.
cortulla's port : This version actually worked but had to wait for atleast 2 hours first boot and even then it ran extremely slow, which was unusable.
As for base rom i'm using nsourm's latest WWE rom. Does this have an effect on android?
Ultimately i think all 3 cards are incompatible, ill try it out on other cards. Anybody have a suggestion for a 2gb card that worked for you?
Thanks
EDIT: Transcend 8gb class 2 worked for me!
Hi Everybody,
today I tested 3 SD cards. I stoped booting time of Android from run Haret to first Android "Lock Screen". Here is my result:
1) Kingston 8GB Class 10
Android booted in 1m 30s
1) Kingston 16GB Class 4
Android booted in 1m 28s
1) Sandisk 4GB Class 4
never booted
And... I solved all problems with Android on my HD mini, because I dropped my phone and is broken... I ordered new display from eBAY (20$), so I hope, will be functionaly.

You need to install new rom (including spl, radio...etc)... Allready confirmed by guys who instaled new rom that all forking perfect now after instaling new rom and radio!!!
RUU_Photon_HTC_Europe_1.36.401.1_Radio_Signed_32.2803.05.06_0.63.05.36_Ship.exe
Working perfect with RUU_Photon_Vodafone_SPA1.41.164.1_Radio_Signed_32. 2807.05.06_0.63.05.41_Ship.exe. Newer ROM and Radio
I've tested Transcend 8Gb class 10 for several days
my conclusion:
compared to my SanDisk 4Gb class 4 is the Transcend at least twice as SLOW in booting Android and apps, is LAGGING a lot and drains my batt very fast!
I'am very happy with the SanDisk

i've recently got my hands on a VOX/s710 phone
my last phone before this used micro SD cards, it was a nokia
when i try to put my nokia micro SD into my VOX, it doesnt recognize, but, as soon as i put it on a nokia, other phones like a palm, etc, it recognizes
is there a problem between nokia branded micro SD cards with HTC?
i tried another brand of micro SD and it worked perfectly
any ideas?
cheers
Initially I tried a NOKIA micro SD card with my Vox and it worked fine.
hum, tks for the reply
so no clues at what the problem might be?
guess if i dont resolve this, ill have to buy another micro SD card
May be, you give a try by formatting the card using a card reader from a Windows PC. That might help.
Yes, make a backup and format to FAT32 (also useful if you want to flash from sd card)! Then put your files back on the card and try again!
thanks for the tips
fortunately, i dont have any indispensable information on the microSD card, i didnt use it a lot, since it was a 1G card, and i had a 2G on my older nokia.
i'm going to try and format it and then post the result hopefully it will work
but since i dont have a memory card reader right now, im gonna try and put it on my old nokia, connect it to the pc and try to format it from there, or format it from inside the nokia phone.
ill figure out something
thanks again for the tips
cheers
=========
tks for the tip tryed it right now, and now its working fine
many thanks both of you for the help!
I have 2 GB microsd card installed. Is it possible to install a 4Gb card or more? Who tried? Does it support SDHC?
Funny thing, I've got an answer from htc support, they say 2Gb is the only possible amount supported

I dont know exactly how to do it search the forum, but i know that there is a thread that says that partion 4gb (using WM5torage that thread tells how to) and then you can use it.
the vox supports SDHC microSD up to 8Gb, found this in www.pocketpc.ch (will post the link l8 when back on my pc).
i'm using a sandisk SDHC 4Gb fat32 formatted, works perfect! i will buy a 8Gb soon and post the results here .
edit: http://www.pocketpc.ch/htc-s710/39075-8-gb-micro-sd-htc-s710-moeglich.html the forum is in german there....
remembered to post this note, after fomarting the sd card, it worked well
just another question though, you guys are talking about 4 and 8 gigs sd cards
doesnt having a much bigger sd card slow down the phone? i've heard of such rumours but never got the chance to tested myself, and since i'm willing to make a sd upgrade i would like to know if its better to stick with a 1 gig or 2 gigs sd card, or i can go ahead and get a 4 or 8 gigs?
cheers
so, finally i bought this fine 8Gb microSDHC from sandisk, and i works just perfect.

i never tried with a 1 or 2Gb card, so there i cannot say. but on the otherhand i did not remark an diffrence of speed with the 4 or 8Gb card, they're just as fast as usual (in cellular device or in pc with cardreader). the only thing i can say, is that cards from cheap(er) brands are always slower than cards from quality brands (such as sandisk, as example). and also SDHC cards should always be faster than 1 or 2Gb cards, because they have a newer controllers (not 100% sure about this point, i think i might have read that in c't).
i hope i could help a little bit...
Dang, 8GB cards work without driver patching? That is champion. I'll be ordering myself one soon.
Yep, can confirm 8gb card works fine, have had one in mine for some months now...
Now what about 16gb? was that article written before 16's were available even the sandisk site seems to be out of date saying nokias that are supposed to support 16's only support 8?
anyone actually confirmed 16's don't work?

i guess we have to wait some time to test it
at work, some weeks ago, i discussed this with a dev. and he meant that from the hardware side it should be no problem, but maybe the driver needs to be updated. i'm not sure, but as i know the driver adds support for sdhc, no matter of the size of the card. he's not a sys dev, he does apps and branding, i'm only test-ex and advanved user, so correct me if i'm wrong (i'm still learning ).
edit: found following on http://www.wisegeek.com/what-are-sdhc-cards.htm
The new 2.00 specification should last a bit longer, as it allows SDHC cards to reach a maximum capacity of 32GB.
Click to expand...
Click to collapse
so i think, if the device supports that specification (and the vox does), it should support cards up to 32Gb.
and again some info about speed:
The SDHC specification 2.00 calls for cards to be classified according to the minimal sustained DTS as follows:
Class 2: minimum sustained DTS of 2MB/sec
Class 4: minimum sustained DTS of 4MB/sec
Class 6: minimum sustained DTS of 6MB/sec
SDHC cards are classified to guarantee a specific sustained DTS. This potentially saves consumers money, as flash cards are priced not only according to capacity, but also to speed. For example, if a product's maximum DTS is 2MB/sec, dishing out extra cash for Class 4 or Class 6 SDHC cards would be a waste of money. Conversely, devices that can utilize the 4MB/sec or 6MB/sec DTR (i guess the author meant DTS, kel187) will perform significantly better with Class 4 or Class 6 SDHC cards, respectively.

my 4Gb card is Class 2 and my 8Gb is Class 4. i did not recognized any diffrences in speed advantages, neither on the mobile nor on the pc. so the vox and my cardreader must be class 2 devices, what a pitty ^^
So today i brought a 8gb Transcend Class 6 mico sd card for my raphael. So i went back home and try it then i found it not detected on the file explorer but it says expansion slot in use when i go to Settings>About. Thanks in advance.
[email protected]
Transcend is not recomended by HTC. i am also having same problem with my SD card which is made by Transcend (4GB capacity). it detects when you put it in phone for a longer time, but you can not write/save/copy anything in it. it will say FILE CAN NOT COPY, MAKE SURE THE PHONE IS PROPERLY CONENCTED AND SOURCE FILE IS NOT MOVED BLA....BLA... BLA...
when i checked with HTC team, they advised me to use micro SD from SANDISK.
well the weird thing is when i insert the card on my friends phone(HTC TYTN 2) it detects it instantly after inserting it in. But when i insert it on my phone it doesn't work, btw i also tried another card from my friend, it a sandisk 4gb and it worked. hmm this seems top be a uncommon issue.
I ahve the SAME exact problem with the 8GB Transcend Class 6 Micro SD that I just bought for my phone. I've had no issues at all with the 4GB Transcend Class 6 card that I currently have. On the other hand, I had a 4GB Sandish Class 6 that would not work in my Raphael but would work just fine in my Kaiser.
Appearently the card worked randomly but i can't copy any file to the card for some reason.
look for something called SDformatter by panasonic i had similar troubles with a couple sd cards till i found this program.
they all work now in any phone/device.
Is there any specific setting to set in the program Panasonic formating program? Erase enable or whatever? I had my SD card working for about 2 or 3 days and now its not detected again.
I have similar my 8GB does not get recognized and if does it's only for a matter of minutes then corrupts but my 2GB reads fine, but the 8GB is fine in Kaiser already used the SDformatter to which makes it read till corrupts again within minutes...
Going to try some other cards out in local shop before purchase will take laptop to transfer data while there.

I have read in a lot of post that Transcend 8GB class 6 card have problems to be recognized by Rapahel.
I also have one. On my Kaiser worked well.
With stock rom it wasn't recognized by Raphael; with Energyrom it is recognized, but i used for few minutes, because i feared that something bad could happen..after reading all these post.
I usually use a Kingston 2gb card.
We were unlucky buying these cards...

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.

Anyone tested the 32GB card, I know it's only class 2....

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

Sorry

Hi folks,
I recently purchased a Lexar Class 10 32GB card for my HTC Desire. In case anyone else was considering the same card, I've written down my experiences with it, such as they are. I've not had it long enough to give any long-term feedback, but I'll update this thread if I encounter any long-term issues with it.
I've also posted this review in play.com but will take a while for it go through their review system.
---
Price: I have been keeping track of this particular Micro SDHC card for a while and when the price dipped to 54.99GBP I took the opportunity to purchase it. Since then I notice that the price has gone up again, so it was a timely purchase.
Delivery: Ordering and delivery was smoothless (ordered on 22/03/2011 and arrived on the doorstep on 28/03/2001).
Usage: I already have a 16GB card in my HTC Desire and required more memory. The Class 10 speed was not a strict requirement, but makes data transfer much faster. There are no compatibility issues with the HTC Desire and am happily using the card at the moment. For those who like to root the phone and so such things, I've partitioned the card using ROM Manager and am currently using Oxygen 2.0.1 with an sd-ext partition and there are no problems using the card.
Data transfer speed: I used h2testw v1.4 to test the card and the results are given below:
Warning: Only 30522 of 30523 MByte tested.
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 10.3 MByte/s
Reading speed: 16.1 MByte/s
H2testw v1.4
For what it's worth I used the Micro SDHC card reader that came with the card on my laptop, which is running Windows Vista. As you can see, the write speed matches the Class 10 specification.
I was not able to achieve the same write speed then writing the contents of the old card (which was first copied to my laptop) to the new card using the card reader on the laptop. I only achieved around 5MByte/s, or thereabouts. This is probably due to the smaller file sizes compared with the file sizes used by h2testw.
Hope this helps.
...and it would be interesting to see it acting here.
How fast does it read using the SD Card reading speed fix?

Thanks for the URL. I'll have a play with it in the weekend and check the speeds.
I got mine too, got around the same results as above. I should do a review soon!
Opinions
Since there are no more reviews on this...guys who bought this card, could you please post how it behaves with the phone?.
Have you noticed any changes like:
- faster video playback
- no lag while recording 720p video
- games and apps loading faster
I'm really considering buying this card, but judging the Amazon reviews the transfer speed for some users is lower than with a class 6 card.
Thanks
32GB? i thought Desires could only read SD cards up to 16GB?
No, I have a 32GB fitted with no probs (yet!).
I'm not a speed merchant, but do not notice any issues.

Everything is smoother for me. I get ~10MB/s write speeds.

Sent from my HTC Desire using XDA Premium App
...got this card yesterday...
...I'm currently running RCMixHD V3.6.1 ROT D2EXT rom on it, partitioned FAT32+EXT4+EXT4+Linux Swap as specified by the requirements of the rom.
Due to the nature of the D2EXT rom running entirely from the EXT & swap partitions off of the SD card, a slow 'lower class' sd card will end up creating a performance hit on the phone.
However, I can confirm that after using it for 12 hours... the D2EXT rom is running very fast and stable on this SD card.
In fact, I would go far as to say the rom running faster than its optimised DATA++ variant.
Thanks to this SD card, I now have a rom that basically has the speed and stability of DATA++ roms but with the added bonus of having over 1GB internal phone memory courtesy of D2EXT... ^_^
I thoroughly recommend this SD card if you can get it... and install Robocik's D2EXT rom on it.. ^_~
have this card as well with my miui rom D2EXT. runs a treat, games have no slow downs.
got the same speeds as been mentioned already here. Def a step in the right direction i say.
I trying to get good speeds with sdhc class 10 micro card.
with stock froyo I get 10 write and 8 read speed.
after patching the fix "kernel_2.6.32-frankoid" the write speed is go down to 7-8
but the read speed is incrased to about 20 with I mesured with sd tools program
But when i conect phone to pc write is max 5 and read max 14.

Hi folks,
I recently purchased a Lexar Class 10 32GB card for my HTC Desire. In case anyone else was considering the same card, I've written down my experiences with it, such as they are. I've not had it long enough to give any long-term feedback, but I'll update this thread if I encounter any long-term issues with it.
I've also posted this review in play.com but will take a while for it go through their review system.
---
Price: I have been keeping track of this particular Micro SDHC card for a while and when the price dipped to 54.99GBP I took the opportunity to purchase it. Since then I notice that the price has gone up again, so it was a timely purchase.
Delivery: Ordering and delivery was smoothless (ordered on 22/03/2011 and arrived on the doorstep on 28/03/2001).
Usage: I already have a 16GB card in my HTC Desire and required more memory. The Class 10 speed was not a strict requirement, but makes data transfer much faster. There are no compatibility issues with the HTC Desire and am happily using the card at the moment. For those who like to root the phone and so such things, I've partitioned the card using ROM Manager and am currently using Oxygen 2.0.1 with an sd-ext partition and there are no problems using the card.
Data transfer speed: I used h2testw v1.4 to test the card and the results are given below:
Warning: Only 30522 of 30523 MByte tested.
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 10.3 MByte/s
Reading speed: 16.1 MByte/s
H2testw v1.4
For what it's worth I used the Micro SDHC card reader that came with the card on my laptop, which is running Windows Vista. As you can see, the write speed matches the Class 10 specification.
I was not able to achieve the same write speed then writing the contents of the old card (which was first copied to my laptop) to the new card using the card reader on the laptop. I only achieved around 5MByte/s, or thereabouts. This is probably due to the smaller file sizes compared with the file sizes used by h2testw.
Hope this helps.

I bought a mustang 32gb microsdhc class 10 card, that am not satisfied with.
It say it will do minium 10mb/s but it does minium 8mb/s
and at max it dosent even go over 10mb/s
While i bought an A-Data microsdhc class 6 that mostly write at 10mb/s
I have a Desire HD and recently started using Lexar 32gb Class 10.
Using SD tools on the phone it says 11.3MB writing speed and 20.8 read speed on average!
When tranferring contents of my previous SD card from PC to the new Lexar using the USB adapter included the transfer speed never got above 10MB/s.
No problems yet. Runs smooth
here is my finding compared to my previous SanDisk 8gb Class 6 card... not sure if im impressed or not..
So does this match other people experience.. im currently on none Rooted Froyo.

I find the files copy quicker to SD cards via a USB adapter. apart from that, I don't like Lexar SD cards very much, I've had better experiences with Sandisk and Kingston, though I've never had a 32GB one, just 16GB and below.
I bought this for my phone, and it is not working Lexar 32GB Mobile Micro SDHC Card- Class 10
I don't know what cards would be compatible with this phone, but in the past I've found that formatting a card on my PC has sorted non-working ones out on my phone. Have you tried that?
Yes i've tried formatting it in all possible formats.
sandisk worked
The sandisk one worked for us:

known bug - microSD not working
According to several Nokia.com discussion threads, this is a known bug with the 820. The card might work for a few minutes, but soon goes corrupt. The card can be re-formatted OK in a PC, and phone will recognise it again (but only for a few minutes). If you've changed the settings to store photos etc on the card, the camera will also stop working when the card goes corrupt (because it can't store the pics anywhere).
Apparently a patch is due one day to fix this...

I can confirm this through experience. Pretty bad issue since the phone only has 8GB of internal storage.
I have tried the following cards and have had the same exact experience:
Sandisk Ultra 64 Class 10
Kingston 32 Class 6 (I think)
Trancend 16 Class 10
For me, the SanDisk Ultra UHS-1 with 64 GB works fine WHEN I reformatted it on the PC to fat32 with this tool: fat32-format.softonic.de
Before, the phone recognized it, but crashed and I couldn't move files to it. After formatting, no more problems
I have this card here
SanDisk Ultra 64 GB MicroSDXC Class 10 UHS-1 Memory Card with Adapter (SDSDQU-064G-AFFP-A)
Worked as soon as it was inserted to the phone and I have several videos and photos on it. 58.X GB formatted capacity. I would not recommend using a card that is NOT listed as compatable with the phone.

Not at the present time ^^

I got an update on the 19th, when the phone restarted everything worked with my Lexar 32GB Class 10(i'd actually forgot that I had it in there), so the issue seems to be solved now.

TurboTuck, thanks for the info.
Have you loaded the microsd with more than 10Gb? Issues usually occurs when more than this amount is loaded to the card.
...mine is working perfectly with a 16 GB class 4 microSD sandisk card.
Anyone tried a 32Gb class 4 microsd?
Just to throw in my .02.. I reflashed my 820 last night and the SD card is still working fine.. It is an 8 gig class 4 I believe. I have a 16 gig class 10 somewhere that I will need to try.
I'm still holding off on really celebrating, though.
Kingston cards work always for me
16GB class 10 here
I bougth a Sandisk 16Gb class 4 and it´s working perfect.
I already loaded it with 12Gb and has no lag at all.
I have 32Gb class 10 from SanDisk. It works perfectly not in 1308 and former.
