Speed difference?

Hello guys, I've got a 2GB MicroSD in my G1... if I buy a brand-new 4GB MicroSDHC class 6, will I have some improvement in general performance of my phone? I have done the partitioning and all that kind of things... thank you!

assuming you are using a class 4 or lower then the answer you will get from XDA is mostly yes.
Some will agree and some will claim placebo effect but my personal opinion is the faster the better.

I've done some test and the maximum speed of my card is 6,4 mb/s.... will the new card improve the GENERAL performance of the ANDROID operative system? Or I will have only some stupid improvement in camera photo saving?

Depends.. the only advantage I see in upgrading your card without using it to store your cache or expanding the amount of apps you can have installed is watching and recording, video and photos, and more space for music or whatever miscellaneous files you choose to store and access

Ok thank you

Apps2SD - Class 2 SD Card ?

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

[Q] Class 6 or Class 10?

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

16GB Class 10

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.

Class 10 Micro SD Card

anyone using class 10 cards on their salsa?
does it help with performance?
any significant increase in speed?

#1. Class 10 SD card means the card is capable of transfering 10mb of data per second.
#2. Will it has noticable performance increase? Well, it depends on which divice you are using it with.
Talking about salsa, I think it wont be able to achieve a noticable difference in perfromance as compared to class 6 SD cards. Reason being, Salsa's overall configuration is not one of the highest. Being said that, it may not have high transfer rate while working with SD cards.
Salsa devs can add more info on transfer rate of salsa.
Check the SD standards official website to learn more about SD cards. Here is the link

Thanks for the information

Yep
It works... I got a 16GB Class 10 card. Much faster than other cards around. Even class 6 is good enough.

I don't think so, the speed of the divice will depend on the slowest process. It will only give higher speeds when using in usb storage.

not in this case, ive used several s cards of various speeds and classes, and each have there differences, hence why when we use them in this phone for a specific reason...a set on is best. ie class 6 or above for usage with ext3. and it does work
