I've just bought an microsdhc from sandisk, and I'm well aware that it's half as fast again the internal SD.
So it will be a nice boost if I can move all installed applications to the external SD. But I don't know how to do it. Could you guys give me some instructions?
Thank you in advance

not necessary at least now as we have 2gig of space on the internal sd to install apps.. and i have 1.5 gig free with almost 60 user apps installed.

I'm not concerned about the space.
I mean we can boost performance if we move all the apps to a faster drive (my sandisk ultra microSDHC class 4 is noticeablely faster than the internal SD)
I found an instruction here: simplehelp.net/2009/09/28/how-to-partition-your-androids-sd-card-to-install-apps-on-it/
but I think it was only for G1 or N1
You cant install apps on SDCard (been an issue for a loooong time in Android), but now its possible with Froyo, which should be available in ~3 months.
Apps2sd will come on Froyo, some custom roms on other handsets (2.1) have it.

Hi,
I have two partition 14 gb Fat32 and 2 gb Ext4 and I want that all installation goes on ext4 (without using internal strorage) so in this case what should I choose Apps2Sd Or Data2Sd?
thanks.
I wouldn't bother with data2sd unless I had a card of class 6 or higher.
I very much agree Class 6+ to get the benefit
Well you would want to choose data2sd, if you want as much to be on the sd-card as possible, however it is usually quite a lot slower than using internal, and there is no reason to leave internal completely empty.
Also you can't run everything from the sd-card. The system-partition will still be on internal as well as boot and so on.

Thank you mortenmhp,
I have sd-card of class 10, will still be a lot slower than internal?
thanks.
I use class 4 and have done from day one with droidzone's roms and it runs great.
I use a class 10 8GB card, and use Apps2sd. Dont really feel the need to use Data2sd.
Ive got alot of apps and still got some memory left so its all cool
Well it might not be too slow, but only do it, if you need the space, in which case it's a good solution.
But the more you move to the slower memory the more time will be spend accessing it.
But I'll encourage you to try it out for your self, as it's very individually(just make a nandroid backup and try different rom solutions) personally with my sd-card there is no way i'd use it for everyday use(flashed it a few times, and always got a slow and lagging system), while other people seem to have it working fine
Ok I will try,
Thank you mortenmhp...
Your question should be which do i need?
People rarely 'need' data2sd - apps2sd is 'usually' enough!

thanks for the infos
how do you know what class your sd card is?
there is a figure 2 or 4 or 6 or 10 in a circle printed on the sd card or you can install sd tools from market to benckmark it ( 2 means 2 mb/s , 4 means 4 mb/s,... aso )
i'd say go for apps2sd then if you need data go for that after

Normally you need a magnifying glass because it is a tiny number............. see figure.

I now use data2sd with MIUI rom and a class 6 samsung sd card £16 from play.com
I would defo recommend this card, I didn't think from class4 to class6 would be that much difference I was wrong. I can now record videos without a single lag, phone is easy 10x faster and smooth, also MIUI is superb rom
Hi,
Most of the times a class 6 or 10 is much "slower" than a good
class 4 like the sandisk mobile ultra of 4Gb (The one of 8 Gb is slow !!).
The problem is that te typical test of writing/reading to/from a single file doesn't guarantee the behaviour of the card when used intensively.
When many files are involved, things change dramatically and a good memory controller is a must, and many of the class 6 /10
don't have one.

I have a 8gb sandisk class 4 in a stock desire and am getting 6.8 meg read and write when I test
Hi,
i have the problem of not enough memory OR a slow system. Currently im using a class6 16gb microsd with default app2sd from the rom (JB spazedog), but the app data fills up the internal memory nonetheless. If i move everything (not just apps) to the sd the system is getting slow and unresponsive.
It is worth getting a faster sd (class 10) and moving everything to sd or do i have no choice but keeping apps to a minimum?
Thx

No, but it would probably be worth to change to some rom which is not in beta and fits in /system small enough to have /data big enough to keep dalvik on nand and give more space for apps.
When using 6class and 10class i feel no significant changes in speed of app2sd area.
running speed test, write speed is usually about the same, read gives little higher results.

I'm using ICS Spazedog and DiskManager is working fine. Sometimes I have to switch pages when looking at app storage to get it to work. Maybe it didn't install properly, maybe your partitions need to be aligned, maybe the SD card needs to be reformatted. Could be quite a few things doing it.
Nope
Class 6 -> 10
If you use App2SD, definitely no.
If you use Data2SD, it is possible to see some differences.

In terms of memory, you have to keep in mind that using a2sd means sending the dalvik (if you choose so) ans the app to the sd-ext. While it allows to more internal space, it still decreases.
The sd-ext partition is practically limited to 1024mb by the desire inter storage size too, meaning that going over 1gb of sd-ext size wouldn't be better.
Now like erklat said, it is better to switch to more stable ROM as JB ROMs offer few space and their behavior have not yet been standardized.
Recap: In terms of memory, it is not necessary to change to an upper class, but it is always a nice harmless improvement.
In terms of speed, I have seen that changing to class 10 gives great speed changes in terms of massive gaming:
Due to the higher read speed and also with the read ahead bumped I was able to increase greatly the loading time of such games as Modern Combat 3 and Nova 3. I was surprised since I thought that it was because of the processor mainly that it was so slow. There is an increase in performance when switching to an upper class, but frankly you cannot notice it unless you benchmark the results by testing with a ressource eater app.
To recap: It is worth the change only for the read speed. I'm not sure but I think that write speed is somewhat limited somehow by the hardware. (I'm thinking about windows here, if someone could confirm that please. )

I am using class 10 transcend 8gb for spazedog JB rom and class 6 transcend 8gb for cm7 rom. No issues.

Planning on getting either a 32gb or 64gb depending on the price.I planned on using app2sd mod to use the micro sd as my main storage instead of the 16gb internal storage. And the micro sd card has to be in FAT32 or EXTFAT format.
1.What the real big difference between class 4 and 10? Beside the price? Is class 10 speed much noticeable or just a minor improvement from class 4?
2.Since i plan on using this as my main storage. Will opening app/games, playing music, viewing video/picture and saving picture on a class 10 be a lot faster than class 4? Also how about coping the files from pc to sd card? Any difference?
3.What brand would you recommend? Is there a difference between a sandisk class 10 and lexar class 10 beside the price?
4.What format do micro sd card come in? If it not FAT32 or EXTFAT, can i change it to FAT32 or EXTFAT?
1. Speed. Class 10 has much faster r/w speeds.
2. Not sure how big a difference itll be. Read speeds should be good enough on either for apps. Its hd video and such that will require higher write speeds though.
3. Dont much care for sandisk oersonally. But I think theyre the only ones offering 64gb. Never tried lexar but Samsung memory has always been the best for me. Jus make sure you trust the seller.
4. FAT32, for most. ExFAT for 64gb. Yes you can reformat.

Hi,
my phone is quite "slow" because I must have INT2EXT (without +) because of data/data are too big when using INT2EXT+..
Currently I have quite old 2GB SD card and I would like to know if it will be better with Class 10 SD card 16 / 32 GB?
Do you think it will be much better or not as much to pay money for new SD card?
Thanks
I have ADATA Class 10 UHS-1 32GB card with 1GB INT2EXT4 partition and it is fast enough in my opinion. I don't remember but it seems to me that the speed of memory card is similar to the internal memory. Anyway phone runs great when apps uses less than half of second partition. If they needs more phone is getting a bit slower. I'm using CM 10.1
