In my info...ext2,3,4 etc is the same ....
And who knows wats the best partition for a 8GB SDHC class 2 ?..
i mean how much shud i partition?..for the best speed

The speed is affected by mostly the class of the card. If your card is class 2, it means, that the minimum writing speed is 2Mb/s. You can have any of the partitions you want, but the speed is derived by the SD Class. (Ext2 is fast, Ext4 is safer, but slower, i don't use ext3, fat32 is medium in every aspect, but has drawbacks (max. 1gig files)).
if you are using custom rom...just dont create any extra partition...
i use the native way..well most of custom roms support this, i suppose

so i am using ext3 partition 300 mb..is it recommended?
i am using link2sd in 2.1
first i create ext3 then at application linking time my phone hand
than i create ext2 my phone work fine
my card is class 4 8gb
thkss
I use ext4 personally. I've heard horror reports of ext2 partition corruption and having to format and lose data. Basically, speed-wise
1st: Ext2
2nd: Ext3 and/or Ext4 (I think)
Fat32 --->?
Ext2 gives you best speed but is less safe than Ext3 and/or Ext4, Ext3 is a middle ground, Ext4 is quite safe but is slower than Ext2. I got a 1137 highscore in I/O in quadrant advanced, you get higher scores with Ext2 I think...
Fat32 is default
P.S. I'm using GingerDX so you might want to base the speed of Ext2 using GingerDX.

You may want to upgrade to Ext4. It has some better aspects but parted can't resize it . I use 512 MB Ext4 partition on my default 8GB sd card found in the box (obtained during promotion) and things still run fast. It's your choice.

I'm not sure if mine is class 2 (dumb sandisk didn't put symbol there), I think it might be. My write speed (as measured using SD Tools) is about 13 MB/s and read speed is about 20+ MB/s. If mine is class 2, then it doesn't appear to slow the phone down. But I don't think mine is class 2 and I have heard reports that data2sd on class 2 sd card lags the entire phone down like sh!t.

I think yours is class 10....because those classes are classified as
Class 2= 2MB/s
Class 4=4MB/s
Class 6=6MB/s
Class 10=10MB/s
How do i check am i using data2sd ?...
open root explorer or a similar app that can access /system files. Go to the root directory. Then, open /sd-ext. If there are folders inside you probably are using data2sd.
Note: data2sd is moving /data/app and some other stuff to /sd-ext. I think sometimes it is called a2sd or app2sd. I also use dalvik2sd .

Well, first thing you do is make sure that your app that is testing the write speed is not on fat32 app2sd (on fat32 partition of sd card), move it to phone memory and recheck the write speed.
As long as you feel that there isn't really much (or any) lag at all while using a2sd, then yes it is fine to use a2sd even on a class 2 sd card.
Note: Lag can occur when using incorrect settings in smartass module or having very little ram, even when not using a2sd.

Basically, as long as you feel that the current lag (if any) is fine, then you can use a2sd all you want.
To test write speed properly, move your app that tests write speed to the phone and then retest.

is it even worth it ro run an ext 2/3 setup with app2sd on a stock g1 sd card?
it would let you have apps on the sd instead of the phone and free phone memory but stock SDcard slower than a class 4 or class 6 sdcard

yeah of course you should run it my friend has had nothing but a stock 2gb and he has had no problems plus upgrading to ext4 always helps see sdparted for help on that
hope this helps
perfect, thanks.
This is probably a dumb question. Do I need to do anything different to enable it to utilize the sd card to run apps off of it or is it built in? I read that cyanogen's rom was built in like that. I keep downloading apps and I don't want to run out of memory on the phone. Do I need to do anything to also use the sd card as ram?
I am using SuperD and jus partation your SD card and should all go well
Yeah it is working fine.

What do you mean by "something different" Different from what? In order for CM to automatically do apps2SD you need to have an EXT partition as your second partition. This can be an EXT2, EXT3 or EXT4 type partition and can be easily created by using the latest Amon_Ra Recovery Image (available here http://forum.xda-developers.com/showthread.php?t=566669).
Nothing else is needed. I see most signatures showing 512MB of EXT partition. I use the same and it has been more than enough for me.
Also, it is recommended that you use a class 6 SD card because the class 2 that came with the phone may not be fast enough and may cause some lag.
Thanks QMAN.

I think you answered my question perfectly. When I put the Dwang rom on and updated to Amon Ra Recovery Image I followed instructions that had me partition the sd card and put ext2 or ext3 type partition. If I buy a class 6 SD card I imagine I can just partition it and put it in.
So to be clear, does then enable the apps to run off the sd card or to install onto the sd card and run off the card also? I mean is it using the sd card as some sort of ram or is it just using it as more of a hard drive? I'm going to guess it is just as a hard drive. I didn't designate anywhere to tell the phone to use the sd card as the installation place for apps. That's why I am kinda wondering.
Thanks

It will both install on and run from sdcard. you don't have to enable anything.
dwang's rom does it automatically as long as you have the ext partition. His however does not support ext4.

Is there a way to see how full the partitioned part of the sd card is getting? When I use settings I can see the fat 32 part I believe, and the internal phone memory. I have Astro, but I don't see an option to view the entire sd card's usage.

That is exactly what I wanted to know. If I keep installing apps till it runs out of memory I'm guessing I won't know till it says it can't install anymore at some point.
Hey Djn I can't see the partitions with Dwang or do I need to specify something. I only see total space 449mb(i'm guessing that is the fat 32), available space 334mb. There is the internal phone storage section also.
this is what I see
number start end size type file system
1 512 472 472 primary fat 32
2 472 984 512 primary ext2
3 984 1016 31.8 primary linux-swap(v1)
So does it mean I've only used 40mb from fat32 section, but I believe I've used more than that? The ext2 part ended with more than it started, so does that mean when I partitioned it, the memory was increased? From number 3 it looks like 32mb was taken right off the top for ram?

Can you tell me what that info is telling me? It is a couple posts up. I understand the total sd card, -32 for swap yada yada. Just not sure if when it says "end" if that means that is what I have available now.

2 472 984 512 primary ext2
3 984 1016 31.8 primary linux-swap(v1)
Block Start End
Well the above tells you what its for, and amount of space for each partition from starting point to end. 1 app is less than 3MB excluding games so if you have 150 apps you still have a good deal of space left.

I don't put mp3s, so other than wanting a little faster load app speed with class 6 I am probably fine with my 1gb class 2 for now. I think most of the apps I have were less than 1mb. I imagine games are larger. If I happen to add mp3 and games will the phone warn me as I get close to filling up the sd card?

i was told that it is way to big of a partition. i would like some more input as to why it is too big. i have a 16gb sd card and not concerned about space. will it give me performance issues? also should i convert the partition to ext3?

I remember reading somewhere here on XDA that 1.5 gigs was the 'recommended' maximum size for your ext partition. Why that is the case, I do not know. It very well could be related to performance, but I can not be 100% sure.
Anyone know why the 1.5 gig restriction is in place?
how can you tell if your ext partition is helping?
so i downloaded apps2sd and repartitioned, but nothing is faster, i see no clarification of speed from it at all....the only thing noticeable is that my 4 gig sd card is now 1.75 gigs......help?

You don't, apps2sd puts your apps on the sd and that is all. It doesn't help with the speed or anything else.

I think you can check sd storage via settings or type df in terminal to see if its being used and how much space is left.
But speed wont be faster or slower with apps2sd.
the ext partition is for using apps2sd, so it will make your fat32 partition for media and such smaller. swap partition is to make things speedier, or supposed to. check settings/sdcard & phone storage/sd card secondary. thats how i could tell by total and available space
so to have 2 1/2 gigs for apps is really a waste unless i want to have 500 apps on my phone......good to know, if i may ask, how do i get rid of that? and how do i get this "swap" partition?
thanks for your replies, theyre greatly appreciated

You must repartition your sd with recovery and choose a swap size...But all your files on your sd will be deleted from your card. And you must re-DL apps from market.I use 256MB Ext cause i install less than 30 apps.My fav app is gameboid/Snesoid so i mainly care if that works.

i used droid swap, but ive only got the stock mem card for now as my 8g **** out on me, and its a class 1 i have been told, which is why i was lagging so much with a2sd. but im pretty sure you can use scripts and such to turn swap on
Im using custom roms for a while now (on GDX26 now). i just move apps to sd, havent done any partitioning and things. so can someone give me a proper noobs guide to app2sd and tell me whats about this sd partitioning and file systems and stuff?
anybody??? :/
Check if your recovery has a Partition option, this is the easiest way to do it. If yes, you only need to give the size that you desire for the partitions. WARNING: all your SD data will be deleted.
If no, you need to use a PC Program, like minitool partition wizard, to create the EXT partition. It's easy: shrink the fat32 partition and create the EXT partition using the left space. The format must be EXT4.
Hopefully, your phone will recognize the EXT partition and will mount it

but can you tell me whats the difference between native app2sd on 2.3 and app2sd with sd partitioning?
oh and whats this swap? its some sort of virtual ram right? do i need it and how do i make it?
Native app2sd doesn't move all the app to the SD (and not all the apps can be moved). Using EXT partition all the apps can be moved totally, so the use of internal memory is minimal.
SWAP, yes, it's virtual ram. I don't recommend you its use, because the SD's life is dramatically reduced.
If you wish to test it, you need to make another partition (formatted as SWAP), either from the Recovery or using a pc program.
