[Q] Could my video recording be laggy becouse of my SD card?

Hy, i have a routed desire running auras 7.6.1 (i think, anyway the latest of his roms) and a kingston class 6 microsd. I have testet the sd on my laptop right after i got it and it could sustain a rate of 7mb/s write and around 10 to read. Now i formated it twice, reinstaled rom and record at 800x600 even if i choose mp4 or h.264 i get an anoying 1 sec frreeze at each 20-30 sec of recording...i mean recording never stops....i can see that freeze only at playback. I tought its the player so i have copyed the movie to pc and i still get the same freeze on pc too, so im thinking its a writing problem on sd card or something...
Ps if i plug my phone to pc and use it as mass storage device and upload a file to phone i only get a sustained speed of 1,5-2mb/s is that ok or is it rly somthing wrong with my card as i suspect...
Excuse my poor english and typing mistakes i send it from my desire thanks.

There seems to be a problem with SD card speeds in Froyo / Sense ROMs. You could try a non-Sense ROM, e.g. CyanogenMod 6, Defrost or OpenDesire - I had similar problems to you and got around them by switching to CM6. If you decide to try another ROM it might be worth using the "SD Card Speed Test" app from Market to benchmark before and after you change ROM.
Let me know how you get on...

Hy, i have tested the sd card with that aplication, i get 2mb write and 4mb read. I have instaled cyanogen and another rom without sense, speed went from 2mb write to 3mb write and that was all...i have tryed it without an ext3 partition also and speed was the same... so i went back to sense rom... since the speed improvement its not much. Maybe someone can recomend me an sd card wich works at greater speeds with a rooted desire, and maybe a place where i can buy it from UE thanks.

that's strange. I have a class 4 Kingston 16GB card and I get 6mb write and 5mb read!

You said earlier that you have a class 6 SD card, so you should be getting at least 6MB/s. Do you have something other than your phone that you can test your SD card in, for example a card reader? That would help you to work out whether the problem is with your SD card or the phone.

if u can recomend me a software to test it in windows 7 x64 i can test it in my laptop

Hy, well problem is solved for me. I have tested the card in laptop and i was geting a 2mb/s write and sometimes jumped at 3-4mb/s max. So i sent it back, and got an A-data 8gb class 6. I pluged it straight into phone, recorded a video and worked flawless, i installed android sd card speed test and i got a write of 6mb/s and 7mb/s read. Afther that i did an ext3 partition on it, and got same write and read speed, so problem was the SD card. Thanks.

[Q] My Desire lags terribly after switching from class 2 to class 10

Hello,
I have bought a Kingston MicroSD 16gb Class 10 card from eBay, although I was a bit concerned(because its eBay), I have received the card and tested it with H2testw v1.4.
The results:
Warning: Only 15475 of 15476 MByte tested.
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 10.6 MByte/s
Reading speed: 18.4 MByte/s
H2testw v1.4
Ive been using Starburst Lite + data2sd rom, and when I got the new card I have reinstalled the rom just like I have installed it the first time (partitioned the sd card with fat32 and less than 2gb to ext4).
Now, the phone keeps lagging, and everything is slower, and I have no idea why.
The weird thing is, when I tried to play Modern Combat 2, it was way faster than with the class 2 card.
I have tried testing the card through the phone with Sdt (SD Card Tester) and it says the card has a write speed of about 2-3mb/s.
I have not tested read speed.
Why am I expriencing this? is it because the way I have reinstalled the rom? is it because the card is fake(even though the program I used to check the card said it was alright)? is it because the facebook sync/google sync?

You phone might lag during the first hours after installing a new ROM, I've had this too.

I had a similar problem with a Patriot class 10 card. I changed to an A-DATA class 6 and have had no problems at all using the StarBurst Main rom. My class 10 card in the phone suffered horrible write speeds, but amazing read speeds (no good for data2sd). The class 6 is WAY better.

ooie: I have installed the rom on the new sdcard last night at 19:30pm, and now its 10:17am.
OpusX11: It's a kingston branded card, and they're considered to be quite good as far as I know.
Also, I have tested the card with my pc, and it had better write + read speeds.

many issues have been reported already with class 10 cards and data2sd coexisting u can check here. i have a class 10 kingmax and have no problems though. since u're using sibere's data2sd (Starburst ROM) did u align to MiB when u created ur partitions, have u done the optimization trick mentioned in the data2sd OP?
Edit: i don't see why u reinstalled the ROM , wouldn't just partitioning the new card do the trick ?

To be honest, I have no idea whats MiB or the other link you're talking about.
I have installed the rom the same way I have installed it on my other card, the class 2 sandisk, which worked quite fast.
I have reinstalled the rom because i'm new to android and I wasn't sure if I had to install it or not so I just did it all again.

if u partitioned ur microsd with Gparted there is an option "align to MiB" (MiB= mb)
the optimization link is from the data2sd thread
this is a line from starburst thread "Data2Sd Re-Installer
If you ever reflash the Rom alone after the Data2SD is installed, some essential libraries required by Data2SD is lost. To restore them, flash the Rom in Recovery, followed immediately thereafter by the Re-Installer.
so go to the thread and download the data2sd REinstaller, flash ROM and then flash the reinstaller without leaving recovery, then reboot and see what happens.

I agree that Kingston normally is a very good brand, i use their RAM quite a bit, but when it comes to microSDHC, not so sure. Search this site for Kingston problem and you'll see the threads I was referring to.

Ok, so i checked my partioning and it seemed like i checked the align to MB thing.
Ive reinstalled the rom, and then Ive installed the Data2SD REinstaller, made a reboot and the phone just freezed at the green htc logo screen.
So ive installed it the way i did the first time and it works again, but slow.
Perhaps its the card? Or the Desire compatibility with the card?
I thought my phone would become super fast, but now it operates even slower :-\

I´ve flashed RCMixHD Data2ext with a Kingston 16 GB class 10 Card.
First hours the ROM feels very laggy, after "sattle down", it runs fast and smooth.

Well I've tried to wait one day but it was still laggy..
It says made in taiwan on my card, where was your card made?

mine is from china

I havent found a solution yet.. i have tried to reinstall starburst a few times, and tried to installed the standard edition instead of the lite edition, and its really slow and frustrating..

You had the class 10 kingston too?
I am beginning to think its the sd card, after I read that its not just about the class but also about the random write speed

Desire freeze with 8GB SD Card

At the beginning sorry for my poor English. The problem with the phone looks like. When I was 4 GB SDHC card everything worked as it should be. But I wanted to change the 8GB SDHC card and I now have the same problems. The phone hangs (only helps to draw the battery), sometimes I have a message about the lack of SD card. I tested on different softs (Cyanogen, InsertCoin, Ace007, MIUI). At first I thought this is a problem with the card. But the two times I was in the complaint and the third I bought another card. Generally, the problem occurred on two cards, Kingston and currently on SanDisk.I have no ideas and the phone is unusable for weeks.
A few data:
- Desire GSM
- Android 2.2.3
- Kernel 2.6.35.14-gingercakes-0.9
- Radio 35.56.00.32U_5.17.05.23
Sierran.

i have sandisk 8gt memory card too and i dont have any probs.. weard, tried to format memorycard with phone?

Yep. Now i flash 2.3 from RUU.. I don't know what's wrong

@UP
Sorry for up but i really need a aneswer :< Today i have 3 freezes in music player app. Now software is orginal froyo 2.2 with stock Hboot.

Try another 8GB card, If everything was fine with the 4GB one, the card should be the culprit.

I tested 3 brand new SdCard's 2x kingston 8GB sdhc class 4 and one SanDisk 8GB sdhc and SanDisk is 100% orginal.

Last @up. If no responde then i close thread.

Hello,
I have the exact same problem.
I have a HTC Desire (GSM) which came with a 4 GB sd card in it, I never had any trouble with it untill now.
I just bought a 8 GB SanDisk sd card to replace the 4 GB one and now the phone freezes from 5 to 10 times a day.
The 4 GB card was a class 2 one, the 8 GB is a class 4 one.
I have to eject the battery and reboot in order to unfreeze the phone.
I was using latest Redux2 ROM, I tried latest cyanogen mod stable thinking the ROM was the origin of the problem => same problem again.
If someone knows how to fix/work around this problem I would be really gratefull
Thanks XDA guys !

[Q] usb speed lower than via card reader (micro-sd card)

hello everyone, first of all few informations:
ROM: Runnymede AIO 2.5.1
hboot: cm7/r2
radio: 5.17.05.08
all works very fine for me, except plugging the phone to my pc...if i copy files to the storage over usb cable to the desire, its about 1-1,3 mb/s and stocks every 2seconds, so if i start to write something to the phone, the computer says for example 1,3mb/s, then the copy dialog stocks at this point and after few seconds it refreshes (windows 7 64bit)
but if i plug in the micro-sd via cardreader, i have min. 10mb/s writing speed and no "freezes"...
i dit try out other usb port, same thing here...card is a new samsung micro-sd 16gb class 6, before i had a sandisk 16gb class 2, thought it was the problem of the card, but now with ne new one its all the same, so i think its definitely a software problem, not hardware.
also i tried the "sd-booster" app and set the cache to 2048kb, but no improvement
anyone who knows that problem or has some ideas?
thanks in advance for solutions

That's probably kernel related.

so what kernel(s) could i try? atm ive got 2.6.35.8-snq-111118.
also, how do i flash new kernel? same as for example radio in fastboot?

I get the speed decrease too, I think it's normal, that's why I always take out the sd if I need to copy any larger files.

yeah sure but i think thats pretty annoying according to the fact that you have to turn off the desire for removing the sd card.
and i thought the usb transfer rate should be at least a BIT faster than 1mb/s with freezes...

you can use 4ext recovery and use the USB Mass Storage feature of it
i have a rate of 5-9MB/s

[Q] SDCARD file system damage issue

Hi,
I experienced following problems :
- flashed on my G3 (D855) Lollipop and after reboot, ADATA Premier Micro SDXC 64GB UHS-I got unreadable ... via Recovery software I got some of the data back, but big files were damaged (I thought it was related to Lollipop...)
- I flashed back to Cloudyfa 1.2 (can't live without XPOSED...), and experienced sudden restarts, while after the restart the sdcard was always unreadable... reformat always fixed it (using exFAT)
- so I thought that ADATA Premier Micro SDXC 64GB UHS-I is faulty and I will got it replaced under warranty
- but to be sure I put it into another device and it's working fine there since week !
- so I thought maybe there is some problem on LG G3, I purchased card Samsung Micro SDHC 32GB EVO Class 10 and guess what - again for a week so far running fine, without damage.... both cards are formatted under exFAT, I have tried to format ADATA it in the phone as well as in the computer....also performed quick and full format - no difference. Performing hard core test in the second device where the sdcard ADATA is still running fine - no issues (benchmarks, manually forced reboots etc.)
So what do you thing, where is the problem ? I can't explain it myself...

my phone did the same problem...
I found a solution. Connect you Sd card to you PC and delete the LG Backup... File it should work back
