I'm seeing intermittent transfer speed when transferring files on the desire.
At first I thought it was caused by the aging (?) win xp. Then I tried on a win7 and the issue is there. the SD card is the 4GB SanDisk that came with the device. What happens is that I copy files over to the SD and it starts quite speedy at 10MB/s and then the file progress bar stops for a few seconds, the speed drops to about 2MB/s, and then the transfer resumes. Before the transfer is complete, the progress is stopped 3 or more times, depending on filesize.
Do you experience the same behaviour? If so, could it be because the SD is only a class 2 card? would a faster card solve this?
thank you

oh, almost forgot. when transferring from the desire to the pc
the transfer is uninterrupted and the troughput is quite high, at 8-10 MB/s. could it be a faulty card? or is this because the write speed is much lower than the read?
thanks again

I have same problem. So it's not faulty. Could be due to sd card speed, but I'm not sure. Think it was faster on my Hero with the same sd card in it.
But so far it works fine, even with the delays. I just try to ignore the delays lol
It's not a deal breaker,maibe a mild nuisance. But since I was thinking about getting a bigger faster card I'm wondering if the nuisance goes away too

Could be the fact that the SD card is only a class 2 card?
I ditched the stock card straight away for my 8gb class 6 and have had no issues with data rate.
I guess that could be the issue. Just a few minutes ago I also noticed the phone lagging a lot while copying stuff. Lagging real bad. I guess copying large movies and using the phone at the same time is a no-go
Or perhaps get a better sd card
I am using Class 6, 16 GB ... no issue with transfer speed.
I noticed that the phone is lagging only when installing apps.
Any suggestions for a good speedy SD?

Been debating whether to setup the apps2sd feature on my phone but after searching about it, not really sure if its worth it from what I gather?
is there any benefit from setting this up?
Also, will there be any negative effect if my SD card is partitioned, and I flash a ROM that does not support apps2sd?
Just thinking ahead. don't want to set my phone up for failure once I get ROM crazy (new to android).
Running DC 3.2.3 btw.
You should have at least a class 6 SD card if you're gonna do it. Basically it just frees up internal memory. You probably won't notice a speed difference on a phone this fast. However, it did improve app loading on my G1. Haven't used it on the EVO yet.

I've checked XDA for a similar thread but I could not find one. Sorry if there's a similar thread though, I'm still an XDA noob
I am using a Kingston 8GB class 4 microSDHC card and most of my apps are stored on it + music, pictures, everything. After (doesn't matter here, it can be 1 hour, 1 day, 5 minutes) 1 hour of idling (standby), the card gets disconnected and reconnects ! I have access to my music and pictures but my apps would simply not work anymore! It's frustrating to reboot my phone just to be able to resume reading or resume my Cut The Rope fun. This can happen up to 4 times a day. It's happening from day 1 since I bought it Is buying another card an option? Is it the phone's fault? Am I the noob here?
u can test it by using another microsd.. if it goes ok, then its ur microsd problem..
if not, maybe either a phone sw or hw..

Thank you very much for your very fast reply. I will get a new memory card and will see how it goes. What memory card do you use? Does your Arc behave like mine?

I use a KingMax 16GB Class 10 card and have never experienced the issue you've described.
As for getting your apps back, I would imagine you'd need to reboot.
hi, i'm using the latest firmware 4.0.2.A.0.58 firmware and I have a problem.
When I insert my 32gb microsd the phone become laggy and it seems freezed.
I tried the card on the pc, did a surface test, and it is perfect.
When I unmount the card the phone works properly.
If i use another 16gb microsd the phone still working properly.
So..what's the matter?does anyone noticed the same issue?
thank you!

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.
Hi,
Im currently using sebastians rom on my htc desire. Everone says it runs super smooth, but im having huge lags. I thought it was the rom, so i tried cool3ds room, which was said to be smooth aswell. Also with this rom, some huge lags.
Both roms use an sd ext partition to store a part of the rom. It got me thinking, could it be my sd card being too slow? I dont know what kinda sd card i have, since i got no knowledge about sd cards whatsoever.
Could these huge lags be causes by my sd card? If so, what sd card would you guys recommend to buy, for maximum performance?
Thanks in advance!
So we learnt what - that smooth and stable terms should be taken with a grain of salt here.
If you don't don't know what sd card you have, I think it is safe to assume that you have a default Samsung class 2 card, which is too slow for anything. Pull out your card and see what number is inside the small circle written on it.

@OP:
To sum up my experiences and what I read, I can recommend a Class 6 SD card from A-DATA, Kingston, Lexar or SanDisk.

Youre right, I indeed do have a Samsung class 2 SD card. Could this really be causing the lags in the rom?
It's not that Im allways experiencing lags, sometimes the rom is super smooth and other times it's soooo slow. For example, when I click the settings icon, it takes 3-4 second before it actually enters the settings menu, and when I scroll between my homescreens, it freezes for 1-2 seconds.
Could a class 6 SD card be a solution? Is class 6 the best to use? I saw some class 10 sd cards around, arent they faster than class 6?
I have a class 4 Sandisk 32gb and seems to work fine
Why not just go for a class 10 card? I got myself a Lexar 32GB from Amazon and every Runny rom is super smooth
Class 10 SD cards are not always recognized by the Desire. So to be sure, one should use a Class 4 -6 SD card. Especially Class 6 works well for all 'technologies' (even DATA2SD).
Is there a noticeable difference between class 6 and 10 when using e.g a runnymede rom? If so, which microsd class 10 cards are confirmed working on the htc desire?

Ye I did. But notice erklats comment. He says class 2 sd cards are too slow for anything. Since I got a class 2 sd card, big chance this is causing the occasional lags.

I did not notice any lags with my Class 6 SD card (in AOSP roms). Never heard / read about anyone who had speed problem with a good Class 6 SD card when using Sense roms.
So in theory Class 10 SD card should work more than ever without a lag. But in practice Class 10 SD cards cause some lags. Don't know why, maybe their are too fast (ATTENTION: dangerous superficial knowledge).

Because sd card is only one side of the coin. Then you have your memory controller and if that one doesn't cooperate with class 10 card, congrats on money wasted.

I'm having the dreaded 'SD Card Unexpectedly Removed' issue. The card seems to work fine in other devices, but my Note 2 cannot deal with it. Mine is a SanDisk 32GB Class 4. It was working fine for weeks, and now all of a sudden, it loses the card every time the phone goes to sleep. Once the phone wakes up, it flashes the warning, then says 'Preparing SD Card', and it works fine until the phone goes to sleep.
I noticed that many Verizon Note 2 users are having the same issue...

It did happen to me with my sandisk 32GB class 4 card. I swapped it with a 16 GB card from a 2 year old
moto droid unused in my basement dump and it worked. It has been over 3 wks now and no issues. I dont think it is a device fault but sense that many note 2 users have bumped into this issue lately..something fishy.

I had this problem also. I had 32 gb class 10 sandisk sdcard 1st time I bought this phone. It was working fine for the 1st 3 weeks but after that I got that dreaded message everytime I wake my phone. I thought its my phones hardware but when my brother and I swapped cards, that message never appeared again. I currently have a 16 gb class 10 sd. My brother has tmobile galaxy s2, that message showed after 2 days of using that card. I reformatted that card and checked it for errors multiple times. There was no problem. I dont know probably some samsung phobes have issues about sdcard 32 gb and above. I have read it in galaxy s3 forums also.

I'm actually having a similar problem with my sn2 not reading my 32gb SanDisk card, I'm going to try to reformat it and see what happens. Just got the phone two days ago.
I fixed my problem by installing the new twrp 2.3.2.3 recovery using goo manager. I followed these instructions from the twrp website.
In goo manager tap menu on your phone and hit install openRecoveryScript, tap yes, verify filename displays your devices name and hit yes. The file will download and install on your device, now reboot.
Hopefully this helps people

I'm just gonna throw this out there... It kinda seems like the latest Samsung phones are happily corrupting SD cards right and left. Now, maybe some cards are more susceptible to this, but the fact remains that this is not just anecdotal anymore. We need to get the various phone groups that are seeing this issue to band together and contact Samsung for a fix.

Mine worked fine for a while, too. I'm not sure what triggered it, but I think the phone did something to it. The reason I think this is simple. I have had many devices with SD cards in them, and never have I had one go bad. This phone was using a card that I had used for months before in another phone, and within a month the card was bad. When I looked online, I found hundreds of cases of the same issue, mostly with Samsung S3 and GN2 phones. It seems too much to be a coincidence.

I am having the same issue. It is with all SD-Cards I try after some time. I have 2 32gb Sandisk class 10 that I tried and a handful of 2 and 4 gb class 4 and class 6 cards. After sometime, 20 minutes to a couple of hours I starting getting the "SD Card unexpectedly removed" Then a quick scanning s Card message. I tried formatting the cards with different computers and even using my Linux machine to see if it would fix it.
Has anyone come up with a solution yet? Should I swap the phone out for another one since I have ruled out the SD-Card as being the problem.
My 14 days hits this weekend and it is easier to get things done at T-Mobile before that time frame expires.
How about card format? All fat32? Exfat?
All fat32 for me. Phone is stock, holding out on root for awhile so I can learn why Touchwiz is so hated.

I formatted mine to exfat to see what would happen. I checked online and this phone supports exfat natively. I moved my files back on to the card after the format and then tossed it in the phone and it worked. It has been over an hour and still has not removed itself unexpectedly.
Will report back in tomorrow after I give it some time to settle.

It is still removing itself almost everytime the phone goes to sleep. The last time it actually unmounted and tols me it was safe to remove the sd card when I woke the phone up.
What cards are people running? I have 2 I am testing this with:
SanDisk ultra 32GB SD-HC U1 (comparable to class 10), 1 is formatted to exfat and is half filled with mp3's, the other is fat32 and half filed with mp3's.
The mp3's are different on each card, I have a folder of music that I always throw back on the card but thought it might be corrupted so last night I made a new folder and added fresh music to see if that was the issue.
I found the official sd formatter program from the SD Alliance to try. I just formatted 1 of the cards with it and am moving the music back now. It will be a while though. From sd to computer the speeds are 12 to 30 MB/s but from computer to sd it is 2 to 5 MB/s?
Hope to have this figured out by the end of the day.
