In short:
Is there a thread somewhere stating the pro's and con's of running Android from different types of "media" (SD, NAND, EXT2)?
If there is, please provide a link, I can't seem to find anything that isn't an unanswered question or small comments.
If there isn't, let this be a starting point for those looking for the answer to this question.
Longer:
I've seen this question pop up once and again but it might be that the topic is totally exhausted and people have stopped commenting on it. I can't seem to find an answer though; What are the pro's and con's of using NAND, EXT2, FAT32 or any combination of it?
I see a couple of installation alternatives and some I have been able to conclude myself but others not.
* Running from SD-card using HaRET
This option is the slowest in terms of Android performance. It has the added value of easily getting back to Windows Mobile by rebooting the phone, gaining easy access to the SD card and manipulation options.
* Running the system AND data on NAND
This option has in my view the fastest Android experience. Access to files on the SD card is a bit more cumbersome (there is the SD card split widget APK available but I have yet to see it working) and access to files for manipulation I can't comment on (haven't gotten to that yet).
* Running the system from NAND and data on EXT2
The performance seems almost as fast as the system+data on NAND. I have no idea about the added value of running anything from an EXT2-partition in the SD card but I'm guessing it will be slower. I have no idea if file access for manipulation is easier or not compared to the other options.
* Running the system AND data from EXT2
I have not tried this yet and cannot comment on it. Something tells me it will be slower than NAND because of SD card overhead.

Now, I've missed out on several of the installation options but I'll edit this post as soon as I get to investigating it further.
Any comments/experience/knowledge in this is greatly appreciated, as it can make things clearer as to what options to choose.
Well these are very good question and wanted to start a thread on this matter as well. I also could not find a strait answer anywhere.
I also want to know if there is an advantage using ext2 over fat32.
So, people out there having knowledge about this matter please share it.
Ext2 and Fat32 are both types of filesystem used on various different types of media, including SD card, Hard drives etc.
EXT2 is (one) of the native linux filesystems, and is fully supported in kernel, and is usually faster and more stable in that OS
FAT32 is the 32bit version of the old MSdos filesystem, used up to Windows 98, and still supported by windows machines, but slower and less stable than the native NTFS filesystem used by XP and above.
Nand is actually the type of flash ROM used by our devices, and not a filesystem as such, and running Android in Nand refers to where the information is stored, rather than the filesystem used to store it.
It's equally valid to say that we run WM in Nand also.
I think that in the case of Android EXT2 should be faster and more stable than fat32 since it's designed for Linux, and works better in that OS.
Zenity ik would like to thank you very much as this answers mij questions.
And i think this would many others aswell.
Don't forget - if you format your MicroSD to just EXT2 then you will make it very awkward to transfer files to/from the card on a Microsoft Windows based system.
This may, or may not be a problem for you.
Ultimately, the current ideal situation (IMHO) is to run your OS from NAND, and to store your data (music / movies / documents) on a FAT32 format MicroSD - as this enables you to swap the MicroSD card without turning off the device, and provides best cross-platform usability of the MicroSD for the purposes of transferring data to/from it.
Thank you all!
Thank you all for commenting! I will add your comments to the Android-wiki I'm building as this question could come back repeatedly from newcomers (and old ones who forgot )!

There is a program for allowing the mounting of EXT2 file systems on windows, however they are not signed. This is more problematic in Windows that are 64bit. The program is called 'ext2fsd' and you can get it from source forge. EXT2 is a better file system, and does not have the 4GB file size limit, and does not fragment (although on a SD card, this should not be an issue). EXT2 also has file permissions that Linux understands. Fat32 has no Access control file permissions.
I have just recently got polymod's eclair running with both system and data on ext2 partitions.
my question is...
I am just wondering what the boot order is...
and where(if possible) can it be changed?
system.img in the andboot folder VS system on partition.
I know it can be set in the installer. but lets say I had installed system on ext2 partition. and then later placed a system.img in the andboot folder.
can I swap between the two?
OK...
I figured it out myself,
You can use the installer to select boot options (Not just options to install)
so I have a system and data on partitons. (currently using)
and I also have a second build installed to .img files in the andboot folder. (for failsafe backup)
if I want to swap from one into the other
I enter installer and change the settings for the system and data to
their respective locations and then just QUIT.
I also still have a donut build in the android folder. as well as still running winmo.
quad boot system on my phone...LOL
Now thats a neat use of the installer, I think this find deserves it's own thread in fact, I'm certain others will find it useful
Tanks !

I've done some tries with this doing the partitioning from within android and then formatting the FAT32 partition from Windows 7 but the FAT32 partition doesn't work very well afterward. Really slow and sometimes crashes the explorer. Propably something to do with my SD-card. May try doing the partitioning and formatting from Linux to see if it works better.
Seems to me the main advantage of this option is to increase the size of available data storage which i suspect can become a limitation sooner or later in a pure NAND install.
EDIT: Now I've done it and gone NAND-System + EXT2-Data... Partitioned the SD-card from Ubuntu with gparted. Resized the FAT32 partition and created 3 primary EXT2 partitions. only the second (partition 3) should be used though with the setup I am using. It's charging right now so I haven't tried it out much yet but I will later on. However I noticed that I now have 171Mb free phone storage instead of 30-something that I had before (same apps installed).
EDIT2: Ran gparted again and shrinked the unused partition (partition 2) and expanded the data partition (partition 3) so I now have 369Mb free "Internal phone storage". Haven't noticed any speed differences between this and when I had data on NAND.
nand
By then one question:
If im install android in the NAND is more fast ready? But this process erase WM6?
Because now android work good in my HTC TYNT II but the camera and bluetooth not work and have one or two performance problems and for this dont like delete WM6 of my phone, and for this im use Android from my SD.
But look the NAND option because have a problems with the time live of my battery only lasts 5hours with android and SD.
Thanks for your help and cooperation
excellent thread which answers some questions that I had. Thanks to everyone who contributed. The only question remaining though and I have posted this elsewhere without getting an answer:
I partitioned a 2 gb sdcard with ~1.6gb Fat32 and the rest as a single Ext2. I selected system on nand and data on ext2 in the installer. After installation, it does show alot more memory for data as compared to data on nand, BUT I also have a data.img in andboot which is in the Fat32 partition, with a size around 250mb. The question is, is the data in that file or on ext2? If I backup data from installer, it creates a databackup.img in andboot with the same size as data.img. Seems to me the ext2 partition is just taking up space and not being used. Can anyone more knowledgeable shed some light on this? Thanks.
Not quite sure what is going on there, seems very counter-intuitive, I would have assumed that system on Nand, data on EXT2 would have installed the data partition to EXT2 on SD. This would seem not to be the case in this instance.
There are a few experiments you could try, if you are brave enough, since you may cause problems by trying any of these suggestions, which could mean a reinstall, I leave it to your judgement how to proceed
Ok firstly I assume you have a card reader, since you managed to partition and format the SD card in the first place. Remove the SD card, insert in card reader, delete the andboot folder, or the contents of the folder, ( may be wise to have a spare SD with either a winmo or android install handy at this point, just in case things go horribly wrong ).
Now with the cleaned SD, put it in the phone and boot, it should boot fine, IF the data is truly on the EXT2 partition.
That at least will answer one question, namely, where the heck is my data?
If this works fine, then I'd just put it down to some inner weirdness of android on non-native devices, if it fails then I'm wondering if your EXT2 partition may have problems, forcing the phone to dump it on the first available good partition, namely the FAT32 one.
Oh and if it does fail, you will have to reinstall, since your data will be toast.
Finally, good luck, I await with interest
As I recall, the install has the FAT32/Ext2 options incorrectly swapped. It has been this way for a while.

Great idea, I'll try this on the weekend. I wont delete data though, I'll just rename andboot and backup data for good measure, because I want to be able to go back to the data by renaming it back if it doesn't work. I was also thinking if there is any way to get to the ext2 partition and read it... I'm on xp so I cant do it on my pc, and on the phone, I've looked around in astro n other file managers but cant see anything. But if the case is as golfnz34me points out, then I should just backup the data, and change the option to Fat32 in install and restore data. That should do the trick.

Thanks, will check this out. If its true, then great, more speed for my /data! I wonder how I missed this, been going through these forums regularly...
Ok I checked it out, and golfnz34me is correct it seems.
But now I found a new problem. I backed up data, and in the installer, set the data to SDCard, and tried to restore data. It gives various errors like
Code:
cannot determine filesystem size
failed
failed to format
...some other lines...
losetup: /dev/block/loop2: no such device or address
I created the partition with Paragon partition manager, and after getting this error I rechecked in PPM. I reformated the partition, but still get the error. In PPM the partition drive letter isnt assigned. Or, the partition isnt the active partition. Can one of those be the problem? The volume name is Ext2. Im not very experienced in partitioning etc, apart from normal ntfs partition for new hds in windows, so I didnt play with any options. I dont have a linux system either. Any got any ideas? Any help would be appreciated alot!
Not sure about using partition managers other than gparted, afaik most people are using the Gparted live cd if they don't have a linux install handy.
The errors all point to some sort of problem with the EXT2 partition, or it's formatting.
Also EXT2 partitions do not have drive letters, nor do they have to be active partitions.
Apps and data on SD card.
I cant seem to figure out how to make all the apps and other stuff install to the SD card. Do I have to partition the card into two partitions? or is there a way to install the system to Nand and make all the apps and data go to the SD card? Ive tried setting it to System on nand and data on SD partition but it says no partitions to install to or something.
On a rooted HTC Desire I installed the XDA rom: “LeeDrOiD V2.0 (30/08 l Official 2.2 l FAST l STABLE l OPTIONAL A2SD+)”.
I need to create on the SD Card (of 16GB) a partition EXT3.
I have used Quick System Info Pro and A2SC storage to check and it displays “Information not available”.
I have installed on HTC the utility “Rom Manager” in order to try to create the EXT type partition.
When I am trying to format with Rom Manager the software does not ask me what type of partition to create (EXT2 or EXT3), but only what size to have and the size of swap.
Can you help me by giving advice on how to create the EXT3 partition?
Thank you in advance.
Rom manager creates ext3 partitions.

I partitioned with Rom Manager my sd card with Ext size=512MB and swap=0.
After that, again, Quick System Info Pro say, at <A2SD storage> : “Information not available”.

(sorry for my english)
Did you reboot your phone once done?
I am stuck in the same position, in Rom manager I select the size and swap and then it reboots. It now goes straight to a diagram of an exclamation mark in a white triangle and an Android bot. I waited for 15 minutes and nothing happens. Here I press the oj and there is some information stating that there is some problem with the update.zip. SOMEBODY PLEASE HELP!

Same thing here
I'm just gonna chime in and say I'm having the same issue here when trying to create the partition using rom manager.
I ended up creating the partition using gparted on my linux box, but after copying all the files back to my fat32 partition, and rebooting my phone it no longer recognizes the applications installed to sd using froyo a2sd. (I have not installed old school a2sd yet as it is not compatible with the version of CM I'm using... waiting for 6.1)
Is there a reason the phone wouldn't see the files for the applications? I created my fat32 partition first, then an ext3 with the remainder.
Is it possible to create a 1gb ext partition using ROM Manager?
Hi.
I have an HTC Desire (T-Mobile UK) usng the Pinky Desre 1.8 rom. I have ROM Manager Premium installed, but this only allows upto 512mb for an ext partition.
I have a 8gb MicroSD card and would liike to create a 1gb ext2/3/4 partiton.
Does anyone have any nfo on how I can do this (assumng that ts possible of course)
Thanks in advance

Have you tried
- moving all the apps on the SD back to the phone
- Do a backup i.e. Titanium
- Reboot phone
- Create partition using ROM Manager
- Re-install apps \ Move to SD
I haven't tried ths, but thinking logically, it should work

I have 16mb of available space on my phone with every application possible moved to the sd card so moving them back is out of the question. I guess I could always just do an brainapp sync for my free apps and re-install the rest from .apk. I'm thinking now I'll hold off until I get a class 6 to make the ext partition.

Amon-Ra lets you make bigger partitions that Recovery Manager/ClockWorkMod
There is a way to do this via ADB I believe as well, or a linux partition manager like GParted.

How mine is set up
Use Unrevoked to install Amon-Ra (that way if you enter recovery via HBOOT you go to Amon-Ra
Then keep RomManager installed, if you need to do anything via clockworkmod you can do it via this app, which "fake flashes" the recovery for its purposes, however still leaves Amon-Ra as its permanent recovery.

My unanswered ROM Manager, SD Card Partition post looks like it belongs here
I rooted my dInc with UnRevoked & 4ever and am now running SkyRaider 3.0 Sense (seems stable & fast) and I see that there's an update available to SR Sense 3.1 RC3 - so I figure now might be a good time to use ROM Manager to create an Ext partition for Apps on my 16G Kingston Class 10 SD card - although, so far I've been using App2SD successfully w/o partitioning the card. What's the benefit? The ability to back up apps on the sd card?
Anyway, I did nandroid & Titanium backups and copied my entire card to a folder on my PC.
My first question is what size ext partition should I choose? (I do currently have a ton of apps - but will be paring down to a leaner machine with fewer redundant apps). Also, what swap size do you suggest?
2nd, when I copy from the PC's SD Card folder back SD Card, which files & folders go to the ext. partition? Just the moved apps?. Then, all the rest to the main partition?
Then, do I just mount the card in the phone and run the update with a full wipe?
I already have the Goodies installed but, will I want to d/l the newest kernel?
Lastly, which of Titaniums' batch restore scenarios is best to finish with? Missing Apps w/ data? All apps & system data?
I realize there are numerous ways to go on this but I'm hoping you folks have some experience you can share before I make any major changes to a phone that's really running pretty well.
Please keep in mind I'm working with ROM Manager and I haven't gotten into sdk, adb, emulation or overclocking - yet

(Q1) I have an 8gb sdcard and created a 1gb Ext2 partition using G-Parted (using Ubuntu 10.04 onmy thumb drive). You dont need to create SWAP. I did'nt use ROM Manager as it (a) totally wipes your sdcard and (b) it only allows for a 512mb partition. I still copied all my sdcard data to my NAS beforehand though....just in case
once I parttioned my sdcard,
I did a full wipe (incl. cache \ dalvic etc)
Installed custom ROM (Pinky Desire 1.8 – FRF91 Official Sense Release).
Then re-installed everything from scratch as, like you, was unsure how TB would restore my backups.
Then used TB to restore User apps w /Data. I figured that system apps were easier\safer to reconfigure manually
Once done, and tested - did an"all user apps+system data" backup with TB.
Booted into Recovery, and did Nandroid backup (and copied that to my NAS bos)
Dont worry about which apps go to the EXT partition. As I understand it, most free apps can be moved\installed to the SDCard; paid apps can only be moved\nstalled to sdcard if the developer has enabled it to do so. I use an app called App 2 SD - it dentifies which appa can be moved to sdcard.
I'm pretty sure that there are easier \ quicker ways, and that my way is over cautious, but it was useful in giving me a better understanding of Android.
I hope this helps.
Thanx for the feedback!
Sounds like about what I'll be doing - unless someone comes up with specific details on using ROM Manager.
What's particularly confusing is that even the apps that can be moved to the SD card only partially reside on the card.
Hi everyone,
is there any way to extend an existing ext3-partition (512MB, created with ROM Manager) without loosing the data?
I'm using the DJ Droid 1.1-R1 ROM on a Desire and the internal memory was fine (about 90MB free, no matter what i've installed so far). However after installing a few games today it dropped to a mere 20MB. Is it possible, that the ext3 partition is already completely used and the latest apps were just installed to the internal phone memory?
Thanks for any hint and solution
Best wishes,
hunchi

You can expand the ext3 partition on the SD card by using something like gparted (http://gparted.sourceforge.net/livecd.php).
This is probably not your problem though. Although your apps are on the SD card the data is still on the internal memory and this is what is reducing your available memory.
Thanks for the help! Will have a look into gparted once it gets necessary. Indeed, the problem was somewhere else: After I rebooted the free internal memory went back to 85MB. However I have no idea what caused this memory usage and the memory release after the reboot... Anyways, as long as it works, I'm happy
Thx again!
extend partition
The most efficient way to extend partition, you asked, and will not wiping data.
I think, want to finish this work, use Extend Partition Assistant Professional Edition. As I knew, this software has gained the best opinion by the users.
And I have tried several times, certainly flawless.

My experience with Partition assistant is that it will not recognize a SD card, only hard disk.
I also recommend the use of gparted. But before this action you should save all data (very easy with linux, because it does not hide any files). If you do not have any linux, download ubuntu live cd, burn it and start your computer with it:
http://www.ubuntu.com/download/ubuntu/download
When you connect your phone with your computer, linux should recognize two partitions: The FAT32 partition and the ext partition (you can find out which is which by comparing the partition sizes). Copy their content on an external storage (e.g. an usb stick): Create two folders, one for fat32 and one for ext. Copy the content in the corresponding folders. Partition the sd-card again with gparted or your phone's recovery system. Start your computer with ubuntu live, connect phone to computer and copy the content of the fat32 and ext partition back to the sd card.
Hi,
copy your data to you hard drive and then BU all your app + data with nandroid and titanium backup then extend your partition on windows disc manager and restore everything.

This will not working. Windows does not support the creating of ext partition (much less the change of it).
I used the GParted GUI utility in Ubuntu. Worked wonders for me!
used gparted also, done twice and no issue. save your data from sd.
to do this i use vmplayer and let run ubuntu distri

Are you use ubuntu live cd, if you do not want to get used with virtual machines (vm).
@matdroid
i know about live cd even usb... advantage of vmplayer is that you launch it without any reboot while playing with your current OS. nowodays comp are enough powerfull to supporte both environment. give a try

It's not new to me that computer from today are powerful enough for vms. That's not the point. With live cd's you do not have a running system in background which can disturb. Thats exactly why i use/prefer them. On this way i can concentrate on this one operation very easy. But that's a personal thing.

I'm trying to figure out what format / partitions my sdhc card(s) should be in.
Does the stock firmware require specific partitioning? 1 FAT32 seems
like it would have huge waste due to the FAT clustering system. Would one
say 2gb FAT32 partition for the firmware to use + some sort of ext2/3/4
or other Linux type filesystem for the rest to better use the space work?
Would a linux swap partitition help / be used at all? I have a 2gb (already
formated as a single fat32 filesystem), a 16gb class 2 and a 32gb class 2
to work with.
I figured on partitioning / formatting the large cards with gparted on a
card reader device, then putting the card in the phone.
How does the incredible see the internal user flash space, as a 'second' SD type device?
Do I understand correctly, the system flash is logically treated as a number of filesystems
so they can be 'fixed' / 'updated' seperately?
Like the boot partition, kernal partition, recovery partition, system / root partition etc.
I'm trying to understand how the system a works vs a regular
unix / linux / bsd OS would. Like booting into recovery is kinda like booting into single user
to fix the boot or root partition.
Does nandroid backup the user (internal) flash or just the various
system flash partitions?
Thanks
Mine is just formatted fat32.

Does the stock firmware require specific partitioning? 1 FAT32 seems
like it would have huge waste due to the FAT clustering system. Would one
say 2gb FAT32 partition for the firmware to use + some sort of ext2/3/4
or other Linux type filesystem for the rest to better use the space work?
Would a linux swap partitition help / be used at all? I have a 2gb (already
formated as a single fat32 filesystem), a 16gb class 2 and a 32gb class 2
to work with.
I figured on partitioning / formatting the large cards with gparted on a
card reader device, then putting the card in the phone.

I believe the stock firmware won't be able to see the card if you reformat it in anything besides fat32, but this is just speculation.
You bring up a good question though. ext2 contains less read/write overhead than FAT32, and thus it would seem better to store certain read/write intensive files (i.e. music) on an ext2 partition rather than FAT32.
You could always root, install a stock-like kernel (Skyraider, Virtuous, etc.) and play around with fstab to see if you can get something usable.
I have been trying all day to figure out how to partition my sdhc card to use for Link2sd and have not been able to find a solution. Can someone please help me with this issue?

Just why not use CWM or TWRP recovery to do this? That's convenient, professional and on-the-go

If anyone can help with ideas/tips...
I am having trouble trying to set up a correct/valid SD card partition again that I can use with the Link2SD app.
I am using the latest version of Link2SD (3.4.5), and running latest CM 11 Nightly (cm-11-20140430-NIGHTLY-epicmtd.zip)
I had this working before (a few weeks ago), using Minitool Partition Wizard to create a 1GB partition with ext2 file system.
Since then I did a wipe on the phone, and have been trying to get it set up again like I had it before.
However, now when I try setting up partition and Link2SD, it seems to work at first (it seems to recognize the partition and let me move apps there via 'Create link') - *BUT* if I ever reboot the phone, then the linked apps are not recognized - it's like they vanished! Even though I am not getting any errors about the partition, it is like it can't see it, or the links don't work or something.
I have tried several times 'Recreate Mount Scripts' and reboot, etc. but it has not helped so far.
I have tried this with ext2 (which I know did work for me in the past), ext3, and ext4, but each of those does not seem to work.
I did have luck with a FAT32 partition, but that does not let me take advantage of the latest Link2SD feature to 'Link internal data'...
I guess I am getting extremely frustrated because I know that at least etx2 *should* work, since I had it working before...
If anyone reading this is successfully using CM 11 and Link2SD, can you explain details of how you set up your partition to work (expecially if you have it able to work with something other than FAT32)
I have looked at all sorts of websites/tutorials (which are often slightly outdated, or written for other phones), but I was wondering if I could maybe get details from someone actually using this on their Epic 4G, so that I can compare notes exactly (I am afraid that maybe I am just missing one little detail to make this work correctly like it did before?!)
Thanks in advance to anyone who read this far and can offer any tips, or just explain details of how you created your partition.
Another thing I have noticed... when I create my 2nd 1GB partition of ext2, and try going through this process I described above... as I said it appears to work, up until I reboot, and then apps that were linked are gone... and then if I hook back up to the PC and run Minitool Partition Wizard again, then the 2nd partition now shows as "other" instead of "ext2".
connect your phone to computer and open minitool partition wizard. if you want to create a new partition, the function Create Partition can help you. You need to use Resize partition to get some space from one partition. There will occure an unallocated partition in minitool, then right click and choose Create Partition. You can type the partition label and choose the file system and drive letter. Hope it helps.
