Does anyone know the performance differences between the 4?
I only had a class 2 card, and that's all I can use ATM, and I want to know what the differences you can feel. Some ROMs need different user.conf settings from me to get similar speed results from them. What are the differences really? How noticeable are they and who came up with the class 6 standard for ROMs?
well i have a class 6. b4 that i had the stock 1 gig. i noticed a diffrence especially in the department of apps2sd. things were smoother for sure baicly the class tells you how much data it can read and write in a certian amount of time. read this for a better explication:

I know that, but what I am after is performance on the G1 .

Hello Friends,
Wanted to ask you all if Class2 Sd Card is suggested for app2sd.
The whole reason of buying a 8GB SD Card was to use apps2sd.
But after buying i realized its a class 2 and when I flashed Dwang-v1.11 ROM my G1 is running very smooth.
The latest v of Dwang has apps2sd.
This post is to confirm my understanding and create awareness about the Class 2,class 4 and class 6 SD Card.
Thanks in advanced as I have always got amazing response from all u guys.
Class 6 is recommended.
Yep Class 6 all the way.
The class of an sdcard is a measure of the *minimum* performance.
Not the maximum.
A real good class 2 card can be faster than a bad class 6.
Or, it could be relative to chip yields. Basically, not all chips produced will be exactly identical, some may just happen to work faster than others.
In other words, a lucky class 2 card is fine. The recommended minimum of class 6 increases the CHANCES of having a good experience with it.
I also have a class 2 card, 16gb. All normal Android roms run great with it, but don't even think about running Hero. Your phone is so slow, it's unusable. No problem with any of Cyanogen's roms.
I used an 8GB class 2 w/ apps on ext2 for ages, didn't have any issues. The performance wasn't noticably different when upgrading to an 8GB class 6 w/ ext3. You'll be fine.
Any way to turn off the apps 2 sd on Cyanogen's mod
Hello,
I just flashed my phone with the latest Cyanogen's mod 4.2.14.1 and experiencing a lot of lag while opening any application.
Even the dialer gets stuck, messaging is getting stuck.
It would be great if the apps run on the rom rather then through the sd card till I get a class 6.
Any help is highly appreciated, as I have started avoiding making calls from my G1 due to the lag.
Else suggest a better ROM if there is no easy solution to turning off apps2sd
Worst Class 2

Hi AdrianK,
Thanks for sharing your experience but may be i got the worst quality of class-2 mmc as mentioned by lbcode, which might be causing this problem.

The system applications are stored on the ROM, not on the SD card.

Most roms now, if you don't have an EXT partition, will skip apps2sd.
thanks
Hey thanks will try removing my ext partitions...
Thanks a lot for the help friends
quick question, and im sorry if it has bin answered but... is a 16 gig class 2 sd card stable enough for a sense ui rom to work on a G1 with no problems??
or what a good sd card for the sense ui roms to work as good as the cupcake or the eclair roms?
thanks
For swap, which you absolutely need with Sense, you should use the fastest card you can get, which is currently 6 (although there are some C10 cards floating around, I don't think anyone here has tried them in the Dream).
Honestly on a card like that Sense will not be usable. I have CM6 running with a 64mb swap partition on a class 2 card and I still get the homescreen reloading 50% of the time.

HM, i see...so class 6 is much more stable workin' in other words.
so even if the sd card has alot more space, its still lags since its class 2?
i have cm 6 workin' on mine aswell, and its 16 gb.
but it some times loads up from time to time...nothin' big... i just haven't tried one of those hero sense UI roms on it since i recently got the card and i wanted to know if it would work as good as the cm6 rom( froyo) rom i got on my g1...
Class for sd card's is how fast you can read/write to the memory card. Class 2= 2MB/S and class 6=6 MB/S. It doesn't matter if the class 2 is 128 GB and the Class 6 is 2 GB, the higher class sd card will always perform better. The write limit to my phone is somewhere around 3.5 MB/S, so a class 4 will satisfy that. A class 10 is pure overkill unless you have an HD 1080P camcorder that needs the extra speed.
Heya Guys,
I'm completely new to SGS and Android in general
Bought my SGS a Week ago and im quite satisfied with it so far. ( Got almost stock froyo -- TouchWizGTG launcher and a voodo lagfix )
I wonder now, if there is a major speed improvement with a class 10 microSD Card with the the SGS over the class 6 card. Is the device even capable to handle a class 10 card and is it worth the buy, will it reduce lags? oO
Well, thank you in advance \o/
The speed of the microsd won't affect your system speed, because no critical files are placed on it.. (long time ago there was a lag fix that moved stuff to sd, but the newer ones don't do that).
The only difference would be reading/writing to the SD, and unless you're going to be doing stuff like high res video recording to the sd or something, I really don't think it matters.
The internal SD card is class 6 or so btw, and it works fine. You probably won't notice a difference.
i have my external SD card at class 4, 16 gb, no problems seen in terms of read / write speed.
Oh! Thanks for the fast answers!
Think I will buy a class 6 then. Thank you very much! U saved me alot of money
Hey folks, I used Generic Nook-2GB-SDCard-CW3010-VGCM7InstallerAsALTinMultiBoot-v6.zip to load CM7..but I was wondering if I can load other SD bootable ROMs with this? I would like to try others if I can. The reason is Im having issue with CM7 being finiky on my NC, like lag opening, not being able to open Market. Any suggestions to these issues too? Thanks, really appreciate the help.
You would need to wipe the SDcard before you can try other ROMs.
Also mainly not the ROM causing the lag and unresponsive but rather the SDcard class/manufacture. What kind of SDcard are you using?
it is a PNY 4G class 4...i saw that the class 2 are much better.

It isn't that class 2 is better than 4. Normally the opposite is suppose to be true.
The issue is the class ratings just tell you the sequential write speed of the drive. Which is nice for copying data to the drive, but isn't helpful in determining if the drive is good enough to run an OS off of.
As this thread shows...

The 4K write speed is really important if you are running a ROM from the SD card. And Sandisk does a LOT better at this than other SD cards.
So in this case a Sandisk C2 would likely be better than a PNY C4.

I agree with Ravynmagi - I am running CyanogenMod on my NC using a Sandisk C2, and it is very responsive. I have found others to be not quite as good.

help me decide
I don't think u will notice any significant increase in performance with class 10 sd, well maybe only when u copy/move stuff from/to it...
But for browsing your mp3's and gallery from your phone, class 6 will do just fine, trust me

But for a A2SD or Data2SD configuration in hd2, class 10 sounds to be more suitable.... ain't in?
Well, there is no such big app on android that needs 10 MB/s read/write and/or needs such big amounts of memory which would require it to pull large amounts of data from sdcard...
Class 10 cards are just waste of money since no app can utilize its full potential, hence u don't really need it that much. But if u can get your hands on one, it won't hurt to have it...
But performance wise, u wont really notice any big difference
any good application for measuring data transfer rate on HTC HD2.
suggestions?

I'm not aware of any SD testing apps for WinMo and WP, you have to find them by yourself.
