It states it on LeedDroid's ROM thread. If it does, why are many of the newer roms only ext4 compatible?
i think ext4 and ext3 behave similarily. so it wouldn't decrease the lifespan if u only use a2sd+
i dont know whether this fits to data2sd
i wouldn't be concerned about sdcard life cause there is no really a difference between ext3 and ext4.
But there is a difference between having app2sd or other stuff that put things on sd card to only using sd card to store music or things like that.
sdcard life is mostly about how often is written to a block on it...

Alright, I'm running darktremor a2sd with an ext4 partition in decks 1.2 and loving it. I'm thinking about messing with synergy and know that I would need an ext3 not ext4 partition to run dta2sd. In amon ra you can upgrade from ext2 to ext3 and 3 to 4. Is there a way to "downgrade" to ext3 without wiping and repartitioning?
Thank you in advance for any help.
Not in any recovery that we have available. I thought I read at one point that you can set SD partitions in Linux, but I don't know if you downgrade in that either.
ok, thanks, thats kind of what i thought.
another question for you or those in the know......i'm pretty sure since i converted my ext3 to ext4 and resetup dta2sd that my temperatures have been getting considerably hotter than before. people suggest that that ext4 isn't the best for the life of an sd card because of extra writing going on.....could this extra work also be contributing to higher temps?
I've got my SD partitioned to ext4 on CM7 with s2e and I've haven't noticed a temperature change, but it sounds possible.
Hi!
I would know it's better A2SD, A2SD+ or DATA++ in relation of a Class 2 SD (4 GB included in Desire).
Thanks in advance.
Since the Data++ version is claimed to fit in a 90MB /sytem partition, I assume that in this version a large part of the ROM has been moved to the sd-ext. This allows you to use a smaller /system and hence have a larger /data partition (hence the name). I'm not sure (because I've only read the first couple of posts, nothing more) whether the Data++ also includes a2sd, or just assumes you will keep your apps in the enlarged data partition. It's probably in the LeeDroid thread somewhere.
If you are not S-Off then it's easy - you want the a2sd version, no argument.
If you are, and are using a custom mtd or an alpharev table with a small /system, large /data, you could try Data++. Which is better will depend on which works best for you (in terms of speed, number of apps you need to install). I've never used either, so cannot offer any experience there.

So, the data++ script uses the ext3 partition more than the a2sd/a2sd+ layout (only difference between a2sd/a2sd+ is that with a2sd+ the dalvik cache will also be moved to sd-ext). If you sd card is too slow, there could occur perfomance problems. But I used an class 2 sd card with a2sd+ myself and never had perfomance problems. So I would say it's your choice.
The speed of sd card actually becomes really important if you want to use data2sd (aka data2ext).
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.

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
Ok i going to partition my sd card, im going to make a ext3 or ext4 partition. Enough guides on how to do that. But what are the differences between those two? And ewhat can i do whit this partition? What is the advantage or disadvantage?
Basically ext4 handles larger files and is generally more efficient as it's an evolution of ext 3, don't know if it makes a huge difference.
Hey,
I'm a noob basically, always had rooting/flashing in mind though so last night I finally had a go at it to get better performance out of my poor Desire.
I will say I spent too much time thinking what to choose between Cyanogen/MIUI and went with the latter to reward myself visually from the get go. I might have not got the gist of a2sd/d2ext/d2w, but I chose to go with the latest signed MIUI xj- d2ext in the end and partitioned my SD Card like this: 1GB ext4, 2,7GB FAT32.
Now, I've gotten quite a few FC's and things were sort of laggy, but figured it might be the first day and installing/doing everything at once that's causing this. My SD Card is the stock 4GB Class2 one and while the internal storage is 80% free, what bothered me was not being able to store back my music library, running out of space. The SD Card's capacity now is the 2,7GB, I have about 1,3GB of music and 850MBs or so of misc stuff that I do not know about. Like I said, I might have skipped more than necessary reading about d2ext, but what I'm asking now is:
- shouldn't I be able to use all FAT32 space available for music and whatnot?
- if not, would choosing MIUI a2sd be better?
- would another ROM suit my class2 card better?
- should i just get a 16gb class6 instead?
Thank you kindly.

Yes.
Homever keep in mind that ext partition (for A2SD) can be maximum 1-1.5GB, you might have issues with bigger partitions.
So think if you'll need those 14GB for FAT partition, in my case 8GB is absolutely enough, unless you store a movies on it.

Thanks, the reason I would buy 16GB instead of 8 is a very small difference in price, about 4 euros so why not double the capacity.
What would then be a good partitioning of space? I've read there's scripts, some use 3 partitions, normally I would be tempted to do as before, 1gb ext4, rest ntfs, I guess. d2ext would be the best choice, still, right?
1-1.5gb ext3 or ext4 (for A2SD), rest FAT32 (for your personal files, music, videos etc).
To partition SD use 4ext recovery, or gparted under linux. (you can use ubuntu livecd for example)

Best way to partition the SD card is to do it with in the phone itself using a recovery like Clockworkmod or 4ext Recovery. These software take care of the sequence of partitioning and any other errors that may arise if you try to do it manually using a computer based partitioning software.
My personal choice is 4ext recovery touch with 1GB ext4 and rest fat32. Gives best performance.

Are you saying 1gb gives better performance than 1.5gb or 4ext rather than 3ext or both?
got cm7r2 hboot s-off on slim ics rom. 1.5gb ext3 rest fat
