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
Related
I'm really confused, first with all the different a2sd variants and ones that are made by Darktremor or other people or the FroYo version. This is as much as I know for this app.
Secondly, I really couldn't find any information on doing partitions manually or setting ALL partitions to ext since I have a linux box, I really don't care to use windows to copy over files or whatever. I have a VMware box to do that on my windows machine anyways.
Third, the ClockworkMod recovery has NO options to do the partition following Darktremor's faq, and I don't know if I should install another recovery after flashing my hboot to 0.93 S-OFF (Alpha)
Mind you I only had my android for about 6 days and this is my first one, so learning curve is hard.
Please help
1) the names can be confusing but old apps2sd is an ext partition on your SD card that appears to the system as internal storage. Froyo apps2sd is using Froyo to transfer mapps to the fat32 partition (normal partition) of your SD card. You just need to use context because people tend to use apps2sd for both.
2) you can use gepart to partition. You need a fat32 partition for apps to write to and for any personal data because Android looks to that partition for that kind of data. I have my SD card as 5 gb fat32 and 3 gb ext3. Fat32 goes first.
3) go to ROM manager. Partition SD card. Choose size....there is only 3 sizes though.
If anything I wrote is wrong I'm sure I'll be corrected.
Sorry to hijack the thread, but since this is related to a2sd in general I might as well ask it here. What's the effect of having a2sd+ on your battery? Would it lower battery life due to cache and apps being stored mainly on SD instead of internal memory? I observed that this was often the case when I store always-on apps on SD back on my old Windows device.
So no way of not using a fat32 eh?
It still seems I don't have much space left after using the Rom manager way. I have 120meg free on internal mem.
Could I just format using linux mkfs? I want to make the apps partition about 2GB to hold more apps. Though it seems some widgets can't take putting on SD card, it dissipates.

Widgets must be installed on internal storage, or they wont work.
If you want an easy method to make a ext 3 partition use ROM manager premium from the Market. It will make you automatically an ext3 partition with a maximum of 512 mb which is enough (put swap to 0). Just keep in mind that first inside ROM Manager you need to select the option Flash ClockworkMod Recovery, and after that go to the SD partition option otherwise it wont work. And also remember you need to have the PREMIUM version otherwise it might not work
Now if you want to have more than a 512 mb you can use gparted. It is a livecd which means that can work on linux, mac or windows just reboot with the cd inside and is quite straightforward to use. Hope this helps.
Hello guys, any thought about that issue maybe?

Hi -
I'm getting ready to install CM7 onto my phone, but I'm needing some guidance on getting more storage space out of it. I was going to opt for the App2SD_+ script, but reading through the forums, a lot of people seem to be recommending S-Off'ing the device and installing CM7 partition tables? How is this better? What are the steps? What does S-Off allow you to do that App2SD doesn't. Is this safe and fully tested?
Thanks.
With CM7 Layout you will have plenty of space for apps in internal storage (300mbs aprox). Using this layout all your apps will run in internal storage which in theory is faster than your SD Card, getting more perfomance. However with this layout you can't flash radios using recovery due to a small cache partition, and some ROM's will not fit in new layout, beacuse you will only have 130mb for System.
If you want to do it, go to http://alpharev.nl. It's fully tested and safe. The only risky part is flashing new HBOOT when you S-OFF.

So if I understood correctly, using CM7 partition tables simply gives you more space on your internal memory (as opposed to making the system think a segment of the SD card is 'internal memory'), and by such, the apps you install on your phone are faster, and the method is overall more safer (less likelihood of corrupting SD card etc.)
What if I wanted to have more than 300mb of internal storage to install apps (say 1 GB)? is App2Sd the best method for me?

Yes, check Cyanogen Mod post At the bottom of first post.
Also, you can flash Darktremor A2SD afterflashing CM7 (without boot). After first boot, use connectBot, terminal emulator or simply ADB shell, a type
Code:
a2sd reinstall
Glad i found this post as i was just asking this in another forum. I'm using the stable CM7 and was looking for the best option between:
S2E for CM7 (easy to use)
Darktremors Script (used it on Gingervillain and pretty easy to use)
Custom MTD Partitions (as per your post, also heard it's faster and more stable)
Still researching but any opinions would be appreciated.

CyanogenMod7 gives 302MB of internal memory after clean install.
CM7 partition table is required.
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.

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.

Hey,I am going to "clean" install CM 7.2 Stable.I am done with Custom MTD Partitions and want to set up an ext partition on the SD card and move apps there.
Preparing for "S2E"(simple2ext:https://play.google.com/store/apps/details?id=ru.krikun.s2e&hl=en )
I have got 2GB SD Card.
What should be the ideal configuration for a 2GB card in terms of :
(1)Ext Size
(2)Swap size
And what should it be ? Ext2 or Ext4 ?
According to this :http://forum.xda-developers.com/showthread.php?t=1432459
“Choose Ext2, Ext3 or Ext4 for partition type based on whether your kernel supports Ext4. If it does choose it! If you don't know choose Ext2 to be safe.” Now how to find out whether your kernel supports it or not ?
Does "swap" really make any difference ?What’s up with this “swap” partition ?
It’s so confusing.Some people claim that “swap” is like virtual RAM and more RAM means a more efficient (and faster) device.
Here are the posts supporting “swap” :

While according to “Cyanogenmod” (http://wiki.cyanogenmod.com/wiki/Swap_and_Compcache ) and some member swap doesn’t make any diff .on android devices.
If that’s true and swape is useless then why so many forums going gaga over it on XDA at the first place ???It makes no sense. So bewildering.
Any suggestion ?Any help would be much appreciated.
Thanks.
You should try 256Mb or 512Mb ext2 partition as per your convenience with 0 swap size.
After partitioning your card you need to install an a2sd script and use a2sdgui app to move apps.
Or else you could install link2sd app and i guess that moves apps to ext partition without needing a script.(haven't tried it though)

You've kind of answered your own question with the link you've provided, if you think swap may be worth using, backup your SD card create a swap partition and give it a run for a while, if you think it isnt then backup everything again and create a partition without it. I had swap enabled when I first created a partition but saw no benefit at all.

Moving Applications data to sd-ext slows your phone down.Don’t move “application data” to sd-ext.

Yes ,your card’s speed depends on the class of your card. An SD card's speed is measured by how quickly information can be read from, or written to, the card.Speed varies with the class of the card…Class 2 (2 megabytes per second), Class 4 (4 megabytes/second),Class 6 (6 megabytes/second) and so on…

I used ext3, what experience do you have with ext4?

It's working great and ext3 should work fine too.
Acually ext4 provides better performance with journalling.
If you use an Old CWM recovery, it will convert it back to ext 3 when you backup/restore.
ext3=ext2+journalling
As ext4 is newer file system,new features have improved the performance and reliability of the filesystem when compared to ext3.
Journaling can be bad for the life of an sd-card (coz you do more writes).If you are not worried about life of the card, and the choice is based on filesystem performance only then ext4>ext3>ext2.
Ext4 can be used with journalling switched off.So "ext4 without journalling" will be best in my opinion.
There is a debate going on over it,check that out :http://forum.xda-developers.com/showthread.php?t=800353
Currently running MikG3.11 w/a2sd so have a EXT3 partition for data (I have my /cache pointing there also). I'm looking to move to a JB rom (probably Evervolv - http://forum.xda-developers.com/showthread.php?t=1961602).
How do I need to re-partition my 16G sd to make the most efficient use? It's been quite a while so a quick 'step1,2,3 howto would be great..including suggested sizes, ext3/ext4...)
Recovery is SmelkusMod..
Thanks Tons!
You may not *need* to do anything out of the ordinary.
If your ext3 partition is of a reasonable size, you might be able to just wipe everything (except 'SD card') in smelkus, flash the ROM, and proceed from there. Nandroid first of course.
'Reasonable' means about 512 to me, others may have different ideas.
How big is your ext partition?
The main reason to repartition is if you are having mystery SD card issues or you want to add or resize partitions. If these don't apply, just wipe, flash, and go.

I would. Repartition, 0/1024, ext3, then ext4....i actually do this before any flash. Think about what a2sd does, and you'll realize that if you don't format, your system has to run through more dead data to get to the info it needs

sdcard ext3 .97 used, 1.79GB total.
sdcard fat32 (rest of the 16G)
I had thought that going ext4 was typically recommended for JB. Are you saying first create a 1G ext3, then the rest as ext4? How does that work for transferring files back and forth via usb to a win7 box?
I intend on doing this fresh.. ie, install gbapps and individual app re-installs from there.
I have a lot of opinions on this but let me just try to answer your one specific question about ext4.
(going from memory here, I'm sure someone will correct me if I'm wrong..)
When creating partitions in recovery, you will be prompted to allocate space to three separate partitions, swap, sd-ext, and 'the rest'. You have to choose a specific size for the first two, the third partition gets whatever is left. If you choose a size of zero when prompted, it will skip creating that partition.
So if you follow jwitts advice above, you will answer zero for swap, then 1024 for the ext partition.
This will skip the creation of a swap partition and create a sd-ext partition with size 1024. Initially you want to format this as ext2.
The rest of the SD card will go in the main sdcard partition and will be formatted as FAT.
As a last step you convert your ext2 partition to ext3 (and if you think there would be a benefit, you can further convert it from ext3 to ext4 in a subsequent step.)
Honestly, I installed evervolv over the exact same partition scheme you have already and have seen no need to tamper with it. Obviously others do. I leave you to make whatever decision you feel most comfortable with.
Partitioning is destructive: you lose all the contents of the entire SD card in the process so you need to make a backup first, and I don't mean nandroid. To me it's a bit more inconvenience plus the risk of losing irreplaceable data (ie pictures, music, etc).
By contrast, wiping partitions is routine and doesn't touch the main FAT partition. If you use smelkus to wipe your sd-ext partition (as implied in the oft-repeated advice to "wipe everything except 'SD card'") you should be starting with a pretty clean slate.
Maybe I've had the wrong understanding all this time, but I have been working under the assumption that "wiping" has the effect of deleting all the files below certain mount point.
The contents of your sd-ext folder are just as gone as if you "formatted". There may be other benefits to additional formatting or partitioning, and when you are planning to start from scratch, that can be a good time to do this sort of "preventive maintenance", but I was just pointing out that under normal conditions it is not strictly necessary.
