What are the benefits of ext2 to ext3

As the thread says..
I know ext3 has journaling but any other benefit/performance gain?

How to convert EXT4 to EXT3?

As the title states, my SD currently runs an EXT4 partition, however after reading around on these forums not all roms support EXT4 yet and most want EXT3 in order to work properly.. Upgrading EXT is easy im using RA Recovery Image, however how do you go from an EXT4 back to an EXT3?
I would think you'd have to repartition the card, well thats how I went about it.
It's tricky. usually, once you upgrade to ext4 you can't go back to ext3 without repartitioning.. but there's a work around...
you can turn off the ext4 "features" from a ext4 partition and mount it as ext3....
"mount -t ext4 /dev/yourpartition /mnt"
that would be the basic command. Needs to be rewritten for your particular situation.
You're better off just repartitioning lol.

[Q] Ext3 or ext4

Is it possible to have our data sectors written as ext3 or ext4. I remember from my g1 days that they are supposed to be faster then ext2 never heard a diffenate on that though.... Personal experience is ext3 is fastest but thats just experience and imo, nothing to prove that...sorry if this had been asked I searched and dididn't come up with anything..
A tutorial on how to create a swap partition is also interesting.
Sorry for my english...
Ext2 is used because the way the data is accessed under ext3 and ext4 reduces the life of an SSD. Ext3 and Ext4 would be fine if you used HDDs, but we don't have a slot that big on our HD2s.
Thanks for the response, but I think some of us are willing to cook a sd card if it improves performance.

[Q] Best combination of filesystems?

what is the best combination of filesystems for galaxy 3? I'm using fugumod 2.2BE, and i want to convert filesystems for data/cache/system because in fs.current all filesystems are rfs
My opinion:
System (stl6) = ext4 or ext2
Data (stl7) = ext4
Cache (stl8) = ext2
thank you, ill trust your opinion

Flash fugumod kernel (if you dont have it already), and make a .txt file and write:
stl6 ext2
stl7 ext4
stl8 ext2
Save the file and rename it to fs.convert. Put it in /sdcard/Android/data/fugumod/ and reboot your phone.
trying it now but I am stuck 5 mins at GT-I5800
EDIT: worked tyvm
I do that but after the phone has rebooted I get a Notification "Low on space". "Internal phone storage is getting low." How do I sort the phone to get rid of this message ?

ext4 is uses more space, so delete a few app.
Thanks

I use ext2 for all parts, a bit faster than ext4, because of no log
me i use also this combination:
System ext2
Data ext4
Cache ext2

Its time to partition. A few questions.

Okay, I am now thinking of partitioning my SD Card....
So a few questions:
1. What are ext4, SWAP and any other kind of partitions and the difference between them?
2. How do I partition and what should be the size of different partitions, how many partitions and each partition for what purpose?
3. After partitioning, what next so that all my apps go to partitioned SD Card, like adding a few App2SD Scripts?
4. What exactly are these App2SD and Data2SD Scripts and the difference between them?

See THIS
And also THIS
That was a good read....
But what is "Swap"?
I have no idea what that is....
And is there specifically any difference between ext3 and ext4?

AFAIK swap is a partition that makes it run as ram when its required.. In short for memory!!
And ext3 and ext4 are just linux partitions and ext4 is recommended. Google is always your friend!!

If you are getting some errors/bugs after partitioning, disable swap as it doesnt work for every1
