I know this has been asked a lot of times on this forum but i really can't understand the advantages of having an ext4,ext3 or ext2 file system over the standard rfs. Does this lead to faster r/w times? Also i googled this and found some articles explaining the advantages of using the ext4 file system on dual-core smartphones.
I'm a newbie to Android and don't really understand how it would help on the SG3.
Also needed to know about the differences in the variations of the ext4 and ext2 file systems such as stl6 ext4, stl7 ext4, stl8 ext2.
I am really confused and expecting a reply from someone. Please help.

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.

how de we create ext4 partition?
hey guys was wondering if someone could explain ext3/ext4 or point me somewhere that could explain what it is and how its beneficial. is it just a better form of apps to sd? cant seem to find much on it anywhere thanks!
UPDATE: so researched how its an extention of file system, but im assuming that ext4 for example is most efficient form of apps2sd?

A few improvements over Ext3. Note the fsck speed improvement vs inode counts graphic in the Ext4 article. If you have no need for your sdcard to be easily compatible with Windows, I'd certainly go ext4 with it.
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
I've been hearing a lot about partitioning sd cards and I know it's done in recovery mode.
So my question is - What's the difference between ext2, ext3, ext4 and swap partition?
Please help out!!
ext2 - Linux file system (no journaling)
ext3 - basically ext2 with journaling
ext4 - next generation of ext3 with better journaling and performance
swap - if internal memory should run full, parts would be swapped to the swap space, so it is basically an enhancement of internal memory
Check each out in the wikipedia, its worth it!
EDIT: I'd personally always go for ext4 and 128 swap

Thanks man,
But still I have few more questions..
What do you mean by "journaling"? And why do we need ext, ext2, ext4 for our mobile?
And swap is for enhancing internal memory or RAM?

Journaling filesystem - quote from Wikipedia:
A journaling file system is a file system that keeps track of the changes that will be made in a journal (usually a circular log in a dedicated area of the file system) before committing them to the main file system. In the event of a system crash or power failure, such file systems are quicker to bring back online and less likely to become corrupted.

Sorry I can't elaborate on why Android uses ext4 - I only read that one reason is that it's capable of multithreading. I hope one of the experts can tell us both more
Swap - you're right, of course - is used for RAM.
I dont know if I got ext3 or ext4 filesystem, how do I check it?
How do I format it in ext4? and what partitions?
What are the advantages and disadvantages of ext3 and ext4?
