I am just curious what filesystem is in use on the Inspire. I'm assuming EXT3 but I'd really like to have EXT4 like we had on the Captivate. The phone flew even faster with EXT4 than it did on EXT3 and it flew pretty fast on EXT3 as well.
Pretty sure it is ext3. D1ll1gaf's rom has an optional kernel that runs on ext 2. I have not seen ext 4 anywhere.... But who knows.
i wanna say stock it runs EXT3, and i'm pretty sure i've seen rooted roms running EXT4
^^^^^ agreed.

i am running fresh rom and was wandering if i should convert the ext2 partition to ext3. what are the benefits and is it possible.
ext2 doesn't have journaling and is vulnerable to corruption (though I've never had anything go corrupt when using it on my phone or computer. Because it doesn't have journaling, a lot of people here on XDA believe that it is faster than ext3. I have no opinion as I have used both and didn't notice any great difference.
Can someone please, in layman's terms, explain what ext3/4 is? Also, in what scenarios is the CWM with ext4 support needed?

Ext3/4 are different file systems... Our phone is "native" ext3... Ext4 is a little better...(faster/easier to work with?) Im not totaly sure... I know there filing systems but not much difference in performance
But the new nvflash ext4 is so we can make backups with the ext4 kernels that are out (possibly new roms)

Ahhh, makes sense now. I'm glad I didn't flash an ext4 kernel/rom and get it setup the way I want it and try a backup. that would have sucked. awesome, thanks again.
Yeah I believe EXT4 is faster at read/write operations which should provide better performance for our little blazing beasts, and is also the latest of the EXT file system type. Newer is always better, right?
I am noticing that clockwork now has support for both ext3 and ext4. Can someone please explain to me what I would use ext3 or ext4 for. Are any of the new roms compatable with darktremmers app2sd? I used ext3 on my cliq for that reason but on the g2x with all the confusion with internal and external and internal-external sd, I am kind of lost and need a little clarification if someone wouldn't mind. My sd card i use now I have partitioned to ext3 but so far I have had no need for it and was about to remove that partition but if I may need it in the future when I flash a new rom I will just leave it or upgrade it to ext4. Thanks.
I'm not a dev, so forgive my simplistic explanation. Basically EXT4 is a much faster I/O file system. After flashing a kernel that has EXT4 support my I/O scores in Quadrant Advanced shot up and my total score is now over 4000. Before that I could get in the 3700's. So it makes a big difference there.
As for apps2sd I'm honestly not sure.
So basically it's a more efficient file system.

SSo I guess they are not talking about the sd card?? Just the file system. I think I am beginning to understand> Thank you
Is this just a different type of recovery? If so, is it better to have the clockworkmod? Or is it personal preference? I seen a post somewhere that a guy was using a ext4 rom. Is there roms made for each type of recovery? And can you have ext4 and clockworkmod installed at the same time?

Yes its a different type of recovery that has ext4 support so you can install roms that support ext4 on ext4 partitions. It's personal preference but I use 4ext because it has more options than cwm. You can not have both installed. Also backups from one may not work on the other. Any rom can be flashed with either but only 4ext will allow you to change your partitions to ext4.
I also believe that all ROMs now have EXT4 support. Also be aware that if you're going to use Gene's tool to unroot, you need to be ext3 and not ext4 for it to work. Other then that I agree with gizmoe, a lot more features built in which makes it much more convenient. EXT4 recovery has the check md5 sum built in which is a neat feature I find myself using a lot!

EXT4 is the default for CM7 on the Ace so I don't think it is limited to 4EXT recovery. The CWM that gets compiled with CM7 has support for EXT4, but I'm not sure if there's an option to toggle this in recovery. I believe it is ony an option in the edify scripting.

EXT4 is being used by a good many ROM cookers, but EXT3 is the default for anything that is factory HTC. CM7 went to EXT4 (for some unknown reason) and many ROM cookers thought that this was somehow the way to go, but EXT4 is really only useful in high-end multi-core server farms and/or super high-speed (15K +) SCSI disks; neither of which the Inspire has. I've heard that EXT4 is slightly faster at full disk transfers (like an update.zip package) and that's why I believe CM7 moved to this--to speed installation--but, in my opinion, you'll never really see any other benefit on an embedded device with a serial pipe to a rather slow eMMC ROM disk.
hello everybody!
I tried to find an answer on this on the ROMs thread but I couldnt so here it is;
Can I use ICE DS v 4.2 with ext3 only? If so, can I disable afterwards ext4 support?
Thanks
why wouldnt you use ext4? it's an advantage thou. but if you dont want to use ICE DS in future, just revert to ext3 by using 4EXT Recovery.
For the amount of internal memory that our devices have there is no matter whether you use ext3 or ext4. Also the install script of the ROM itself will format the partitions as ext4 upon flashing so there is not much choise actually If you like to go back to ext3 after flashing 4EXT Recovery can do this without losing any data

Thanks for the quick replies..
When I used a stock ROM with a rooted Desire, I remember discussions about the disadvantages of ext4.
The idea as I understood, was that ext4 was more likely to create filesystem corruption in case of an abnormal shutdown of the phone, eg battery removal, expecially if it used to extend phone memory to the sd card via proper partitioning.
It is exactly the opposite. The ext4 file management will prevent corruption in case that a read/write process gets interrupted by a battery pull or similar. Search Google for ext4 there are all the benefits described on a Wikipedia article.

This.
ext4 wouldn't exist, or developed if ext3 is better.
