SD Card Partition sizes with Apps2SD

Hi everyone,
i was just wondering about what partition sizes I should set for my memory card using Apps2SD as I am a little unsure. I am currently using a 8 GB SD Card.
I was thinking to set it up with a 32mb swap, 512m-1gb ext2, and the remainder as fat32? Is that suffice? the ext2 size I assume is the space I would dedicate for the installation of apps.
Then after that, should we convert ext2 to ext3?
Please advise
Thank you.

I wouldn't use swap at any time. Your phone has 578 MB of Ram - I don't know how much is left for the running system after the substraction for radio, 3d,.... but it still should be around 400MB. Using swap would just slow down your phone.
A 256 MB ext partition for programs is enough.

Kind of depends, I will for sure get a bigger partition then 256MB, some games are 20/30MB in size. Will be nice to not worry about those anymore!

I just installed apps2sd then started installing was I meant to do different? lol

Hello guys,
I'm a newbie with Android.
I've not understood: with A2SD I can "migrate" all apps to sdcard or there is a way to choose what to have on the device and what to have on sdcard?
Thanks,
ghale

I have this question too. are all the apps going to the sdcard or you choose where to go ???? or when the phone memory fills the sdcard is used ???
and another question I have is if the sdcard apps are copy paste backup able

I have read that if set to 0, no swap partition will be created. The default is 32MB.

Im not using a swap.
I just created my ext2 using gparted on Linux. I resized the original fat32 and then used the free space to create ext2. No data was lost on original partition after resize

Hi there,
im not a big user of apps and won't end up installing many to the sd card. Would you suggest I set up the partitions as follows:
0mb swap, 512m-1gb ext2, and the remainder as fat32?
I have also read that if you convert EXT filesystem from EXT2 to EXT3 after partitioning, it results in better stability/performance, and by converting the EXT filesystem from EXT3 to EXT4 results in best stability/performance.
Can anyone clarify this please?
Thanks again in advance.

EDIT
Found it !

This is where i'm getting confused... this article, for example, states to allocate 32 MB to the linux-swap partition, 512 MB ext2 partition, and remaining free space as a fat32 partition (for an 8GB SD Card).
It also states this is the most common setup...

I used 980mb for my a2sd not swap and everything seems to be working just fine

Im just thinking... the Android OS is designed to do this for you, when it runs low on free memory it starts closing apps based on a ranking system for deciding which is 'least important' to avoid actually running out. If you later switch back to an app that the OS has removed from memory it will be reloaded from internal storage which won't be as quick as if the app was still in memory, but on the other hand it won't be any slower than if it was being loaded into RAM from the swap partition on the SD card.
Actually, I can't see swap helping... Either the Android OS will avoid running out of physical memory as it's supposed to and never actually use the swap partition, or worse it does actually use it as if it was extra physical memory (unlikely, I think) which will interfere with the sophisticated memory management scheme that's already there. Is this the reason why Android phones don't ship configured for swap? maybe because the OS is already doing something better that makes swap unnecessary?

guys I just flashed apps2sd and installed is that wrong? what else do I need to do

As long as you followed the correct procedure (accessing recovery, installing the Apps2SD.zip file via recovery and set the partitions), then you are set.

Well, what would be the point of installing Apps2SD then if you did not allocated extra space to the ext2 partition
Backup everything on the SD Card before attempting:

I didn't know just flashed it, sorry to be a pain but what's the process now? hard reset? will I have to reinstall apps2sd? first time I've ever used it

You will not need to hard reset, just access recovery again via Linux and select the option to Partition the SD in recovery mode, enter the partition sizes you want, then you may want to select the option: convert ext3 to ext4 for improve stability/performance. Yes, use the Gold Card SD.

That depends, does the rom suggest a partition type to use? And what do you intend to use the partition for? And fyi clockwork mod recovery can partition your sdcard
sent from my android powered beast!

Step 1. Read the forums, use the search function & ask the Oracle(The all knowing all powerfull Google)
No no, that can't be right.
Step 1. Launch ROM Manager.
Step 2. Partion SD card
(I believe this makes an ext3 partition)
LOL
Back up your SD card fist duh!
In mini partition
I would format the card. Then right click and create each parition from the unnalocated space. Fat32, then ext2/3/4 depending on your rom, set all of these as primary. Now make a Linux swap and set as logical.

Swap Parition ?

Hello. I am new to this forum. I am curious how many people really use a swap partition and what is the method of of using swap in htc wildire s?
I am well aware of Linux OS and understand the need of swap but in case of android does it really improves something?

Hi.I will try to explain you what i know: :laugh:
-swap partition is needed to work some ROM's,combinated with ext partitions.
-you can create swap partition with MiniToolWizard
-in same time,you can create with CWM recovery.
If you need,i will give you a link for MiniTool.
If i helped you,please click "Thank's" button.Have a nice day !!

Does android automatically detect SWAP Partition on SD Card and utilize it automatically?

Yes(i think).
Sent from my HTC Wildfire S A510e using xda app-developers app

does it? i thought the kernel had to had zram enabeled to allow swap use? i might be wrong though..

Most roms auto-detect, but I'd recommend checking with the devs before partitioning your sd card.
Also, unless you have a class 6 or upwards, it won't really do any good.

Where did u find that info?? Is class 4 mmc that bad????:s

never use a swap partition on any android phones. It does no good. The swap partition are made with your sd card which is more than 10 times slower than your internal memory. When an app is loaded or is sent to swap partition cache memory, it takes time to copy or load the files.
Android already has a system for moving unused apps to cache memory. So, let android do its job.

Just ignore his comment. We need Linux swap. Without it phone gets laggy. I tested it myself.
Download minitool partition wizard home edition. Its free Google it. After installing it and insert ur sdcard via card reader and run the program.it will show ur partitions.
You don't need to uninstall ur system. Just make nandroid backup using recovery. Re format only the ext and swap partition. Based on wat ext u had earlier. All partitions should be primary.
Then from advance recovery restore sd-ext.

@Edu: just search xda for details of swap partition. There have been number of discussions regarding it and all have ended up denying the use of swap partition. These have been comfirmed by much experienced devs, who have been cooking roms for more than 3 years. But still if you dont believe, i would recommend you to google a little and then make the decision.

But sir without it the phone gets very laggy. Means every games run slower. The antutu gpu score gets lowered.
U can easily get 645-630 3D with swap. But without it u can't cross 615. That may seem as little gain but for games it becomes a big issue.

Maybe that is because the extra cache memory are directly transferred to swap memory. Games which require huge cache memory can be of profit. thanks for the screens btw
@op : just take nand back up and back up your sd card. Try the swap partition thing and if it is beneficial, go ahead or else you know what to do

Swap Partition
Hi, i'm new here so i'ld really appreciate anyone who can really help me on this:
I created a swap partition(256mb) on my sd card for my HTC wfs. now after making series of research on swap partition, i found out that swap parttion is necessarily not needed and even if i av to use the 256mb i allocated is too much. Now i need help on how to delete the swap partition without losing my DATA ON MY SDCARD. PLEASE ANYONE WITH THE RIGHT HELP

that's kinda not possible i guess..with mini partition tool you can delete swap or ext3 partition and create ext4 visa versa..but if you wanted only fat32 it isn't possible.
either if you have ext3 or ext4..open mini partiiton tool..delete swap and delete ext3 or ext4(which one you have)
and create partition(ext3 or ext4) from remaining free space...in this your fat32 will be unchanged..
but obviously ext3/4 will be deleted..bt its okay to hv swap partition..256 MB hasn't big space..the whole concept of swap derived frm link2sd i guess..latest int2ext scripts dont need swap..but int2extv2+ need.

Copy all of your data to your pc, then format the card via clockworkmod recovery. It should remove the partition. If not you can try gparted for linux or easeus partition master for windows pal.
If your trying to keep your ext partition but without a swap then copy your data to the pc, then select partition sdcard from clockworkmod recovery. Just don't select a swap and you will be fine
Oh, and make a nandroid backup to back up whats on your ext partition

thanks dude really appreciate but going by what you said i have ext3 and already used a2sd that means if i delete ext3 definately i'll lose my data. that is what i'm trying to avoid but since you said my 256mb aint much a big deal, i think i wld leave it then.
Thanks a bunch.

Better system of partition

Hi everyone.
I have my SD Card with DATA2SD, but I've problems with fluidity and lag of the ROM (CM9 and ParanoidAndroid). ¿Which is the better system of partition for a 2GB SD Card?
Sorry for my bad english . Thanks!

Make 1gb fat32, 600mb ext4/ext2 and the remaining (at least or more than) 418 linuxswap. Make sure that all are primary partitions. For link2sd use ext2 data2sd ext4.
Linux swap partition needs to be at least equal to the size of ram.
