[Q] Pros and Cons of sd-ext?

Hi!
Just would like to know the pros and cons of formatting into ext4 on my SD.
As far as I can find :
Pros : Supports files larger than 4GB as Fat32 cannot
That's about it I think...
Cons : Windows cannot natively detect such a partition
Why I ask this is I just saw a this post

I'm ready to go ext4 if there's any performance gain, who wouldn't? But what gain is there, and what would I lose in return?

You're mixing things up here a bit I think. Sd-ext referrs to having a partition on your sdcard to allow support for Apps2SD (basically being able to move apps to your SD card and run them from there in order to free up space); you'd basically repartition the card so that there's an ext3/4 partition for apps and a FAT32 partition for data.
As for the ext4 filesystem, it does allow for larger file sizes and is also a bit faster but you're correct in the fact that you won't be able to natively mount it on a Windows system.

But don't we already have Apps2SD in GB, + all the apps that do it for you. How is this different, apart from some apps that can't natively be moved? And why is it faster? Internal memory should always load faster, should it not?

GB has the ability to do Apps2SD but it requires the partitioning as, I believe, a symlink is set up so that partition on the sdcard acts as a part of the devices internal storage.
As for speed, just moving apps to your sdcard won't speed up your phone; what that poster you quoted was talking about (most likely, I'd have to see the original thread) was converting your devices partitions (/system, /data, /cache, etc.) from ext3 to ext4. ext4 is a bit faster however some ROMs do not fully support it.
Sent from my T-Mobile G2 using XDA App

Ok, let's clear this up. GB has Apps2FAT32 (a2sd) natively. A2EXT is completely different but none of that is the point of the OP's question.
When it comes to our phones - there is almost no notable performance gain when using EXT4 over any other EXT format. Our phones don't utilize FAT32 internally - just on the sdcard. EXT4 is designed for use with massive file systems. A couple Gigs really doesn't access it's full potential.
While the question is interesting, I'm not really sure what you're planning on doing. Don't format your sdcard entirely in EXT format, and don't attempt to format your phones partitions as FAT32. The result would be... just don't do it.

Just read this on the portal
http://www.xda-developers.com/andro...hd2-data-successfully-moved-to-ext-partition/
This has two main advantages: larger sized data partition and more speed as EXT is inherently faster for I/O purposes.

How do I go about formatting a section of my SD into ext4, with existing SD data intact.
And how do I move apps that area already in my phone's internal memory to the ext4 partition? I know there's an option in ROM Manager and CWM, but just don't want to mess anything up

As far as I know, only two ROMs actually support the real A2SD: PyroMod and MexDroid. It's recommended you format the EXT partition to EXT4 before you actually flash either of those ROMs, and you have to rename MexDroid in order to get A2SD working.

Thankfully I am already using meXdroid~ Guess I'll just wait for the new version in the next few days to do the formatting. Can I backup all my apps with Titanium Backup, flash ROM (wipe data/cache and dalvik cache), restore with Titanium.
Or would I have to reinstall every app again so that it goes into the ext4 partition?

There's a script to accomplish this on pretty much any ROM. It *should* work on current ROMs too. It's called 'darktremor a2sd'. Still find it amazing people forget about that one when this question comes up because it's one oldest methods of obtaining a2sd.
I'm still not understanding the OP's question. Are you wanting to do this for an IO performance gain or for space? I can understand doing it for space if you have a ton of apps but if you're doing it for performance it's a waste of your time. You're internal partitions should already be in EXT4 format (use 4EXT Recovery if they're not).

I'm doing it for the performance. Have been using 4EXT for a few days and loving it. Already converted internal memory to ext4 from ext3. If further partitioning my SD card for performance is really not noticeable, then I guess I've got nothing to worry about

[Q] ext4 What is it?!

I have been using a custom ROM for a while now and I have been seeing in the thread that many people are using ext4.
I have asked many times in the thread and recieved no reply.
So my question to you is what is "ext4" and what bennifit will it be to me as a Desire owner.
Thanks

1. Google is your friend
EXT4 is a file format used by Linux (Android = Linux). When threads talk about EXT4, they are referring to creating an EXT4 partition on your SD-Card e.g. have 14GB FAT32 and 1GB EXT4 (from 16GB SD-Card.. 1GB is always non-existent)
What having an EXT4 partition enables you to do, is to have Apps/Data2EXT scripts which move apps to the EXT partition, giving you a lot more internal space.

Moving some of the app data to the sd-card is different to having an EXT partition and A2SD.
If you activate A2SD, the system will install and store your apps on the EXT partition, and your internal memory will not be filled up, and will remain at xxxMB. Furthermore, with an EXT partition you can use D2EXT, which makes your phone use the EXT partition as the data partition, so if you have 1GB EXT4, your phone will see 1GB memory.
If you use the inbuilt "move to sdcard" function, it only moves some of the sd-card to the android-secure folder on your sd-card, however your internal memory is still used up.

In addition, moving apps to sd-ext partition doesn't break app widgets like the stock app2sd method that Gingerbread use.

Reason: With A2SD / DATA2SD / etc. Android still "thinks and tells" the Apps are still installed in the internal memory (at least this tells me my logic).

backup your sd card 1st
then use only 4ext recovery (requires s-off to change recovery) or gparted to create your partition (step 5 here)

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 !!

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

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

SD Partition on 32 GB card?

Hey guys,
I've searched around a lot but haven't found anything explicit to a 32 GB card's ideal partition table. I've read somewhere that the ext3 shouldn't be larger than 2 GB, is this really the case? Or is it device specific? And if thats the case, can the MT3G3 handle a larger than 2GB partition? Also, is there a point to having a swap partition? I know on Linux systems it helps with memory and the XDA SD partition guide mentions that we can have one if we wanted .. but is there a point to it?
My second question is ... should I get data2ext or a2ext? Or some other tool? The choice is pretty confusing, esp since it seems that some of them do the same thing?
I'm thinking about making the partitions equal between FAT32 and Ext3 (if swap won't make a difference).
PS - Its a Class 10 Sandisk card.

don't know what a mt3gs works with, 32 should work but no larger I doubt. as for an ext partition there is no reason to make it smaller than internal memory and 2gb should be more than enough, I have never even used more than 1gb but 1~2gb should be the perfect point.
not sure if any of the roms here support ext4, if they do I would recomend that over ext3, it won't ware the card much fast (the extra journaling does but not much)
personaly kinux swap doesn't help much, not even on the g1 but give it a shot and see if it works for you, will help with multitasking
use apps2ext for sure, not data as it will be slow

I'm not sure if creating swap on sd is supported on this device (at least, CM7). When I tried to partition SD using Rom Manager the device didn't see my ext partition if I selected swap partition size more than 0.
As for apps for managing ext partition usage, s2e app worked for me all right on CM9 and CM7. If you device is running CM9 you should be extra careful with such software. In example, Link2SD caused much trouble for me - constant app FC and I had to reinstall the system.
And be careful - it seems that s2e wipes ext partition at the first mount.

If im not mistaken, your kernel has to support using a swap partition.
Look into darktremors apps2sd. A. Lot of folks seemed to like that. It allows you to choose different setups if I remember right. (A2sd, data2sd, etc)
Data2sd would prob work ok since you have a class 10 card.
Also, if you are needing more space and are running a custom rom, look up mtd partitions in development forum.
Another nice trick is bind-mount data to cache.
Mt3gs does not support higher than 32gb. Ext4 support I think is available but only through kernels or scripts.
Hope that helps.

Different ROMs support different a2sd scripts.....you will have to find a script compatible with your ROM.
I use A2SDGUI on my phone.
A swap partition acts a virtual ram for your phone if you run low on ram memory.Not required though.

Thanks for the replies everyone
I'm running CM7.2 which has built in moving to SD but this hardly does anything :/ I've only got around 7 apps half of which I can't even update cos its running low on space :/
Quite a few partition articles / posts, etc mention ext3 no larger than 2 GB and a swap of 0 MB :/ I've got the CM kernel that came with the last stable release (in June this year) .. does that support swap? Is there even a point of adding a swap of 0 MB .. might as well not make a swap partition at all right? I'm partitioning using Gparted on my Linux! I think S2E supports that!
Seriously guys, thank you so so much for all your replies

Update: Link2SD didn't work. S2E worked on S-ON with a 28 ish GB FAT32 Primary Partition and a 2048 MB i.e 2 GB EXT4 partition.

best way to partition is with gparted or 4ext recovery. 512MB is quite small, i'd recommend larger (up to 2GB max) if you plan on having more apps, saves you re-partitioning later
generally you don't need swap, it's useless, doesn't extend the RAM unless the rom is programmed to do so afaik. don't use swap unless the rom explicitly says so, most don't
a lot of people use swap without knowing what it even is...

Maximum of 1.5gb ext4 partition is always recommended. Best is to stick with 1gb.

the actual size shouldn't affect performance, just the number of apps you can install, and depends what you use the partition for (app apks, dalvik cache and / or data)
just pick a size which you think is best according to how many apps you think you'll need. because that's hard to predict, and after rooting allows more space for apps, so go larger to be safer and avoid re-partitioning later. this sacrifices FAT32 space, so may need to be managed depending on the total size of the card. personally i find 1gb ext4 not enough, i use ~1.5GB. 2GB should be more than sufficient for most (some say it won't work, but there are plenty of users running 2GB just fine)
