MTD still only uses whatever internal memory the phone has.
I myself have a Class 10 MicroSD and half of it is EXT lol.
I also have a class 10 16g. Also is it better to have a large ext cause i tried data2ext with a 512mb ext and it wasn't very good
I am using the custom MTD myself with CM roms. This combination works well for me and is pretty much no-fuss to deal with.
However, if I were using a rom with a much larger footprint, like the CR_Mod-2.13, I would almost certainly go the apps2ext route...
what do you guys mean by class 10?
class 2= 2MB per sec
class 6= 6MB
class 10=10MB
Its the transfer rate of your sd card.
I think it pretty much relies on what you have, I plan on getting a class 10 SD card and use both MTD and Data2ext. Though currently I simply have MTD and put the leftover /system memory into data for now. Class 6 or above SD cards are better for data2ext, otherwise you'll lag your phone badly. I use CM-7 with a bunch of stuff removed and added Genius button, so I have 130 allocated to /system currently. if you use a Sense rom using MTD is almost pointless because it uses the full standard allocation of /system memory. Data2ext would be optimal at this point. So it boils down to what you are/plan on using and what you plan on doing with data.
How big should the EXT3 partition be for data2ext.

Hi,
I have two partition 14 gb Fat32 and 2 gb Ext4 and I want that all installation goes on ext4 (without using internal strorage) so in this case what should I choose Apps2Sd Or Data2Sd?
thanks.
I wouldn't bother with data2sd unless I had a card of class 6 or higher.
I very much agree Class 6+ to get the benefit
Well you would want to choose data2sd, if you want as much to be on the sd-card as possible, however it is usually quite a lot slower than using internal, and there is no reason to leave internal completely empty.
Also you can't run everything from the sd-card. The system-partition will still be on internal as well as boot and so on.

Thank you mortenmhp,
I have sd-card of class 10, will still be a lot slower than internal?
thanks.
I use class 4 and have done from day one with droidzone's roms and it runs great.
I use a class 10 8GB card, and use Apps2sd. Dont really feel the need to use Data2sd.
Ive got alot of apps and still got some memory left so its all cool
Well it might not be too slow, but only do it, if you need the space, in which case it's a good solution.
But the more you move to the slower memory the more time will be spend accessing it.
But I'll encourage you to try it out for your self, as it's very individually(just make a nandroid backup and try different rom solutions) personally with my sd-card there is no way i'd use it for everyday use(flashed it a few times, and always got a slow and lagging system), while other people seem to have it working fine
Ok I will try,
Thank you mortenmhp...
Your question should be which do i need?
People rarely 'need' data2sd - apps2sd is 'usually' enough!

thanks for the infos
how do you know what class your sd card is?
there is a figure 2 or 4 or 6 or 10 in a circle printed on the sd card or you can install sd tools from market to benckmark it ( 2 means 2 mb/s , 4 means 4 mb/s,... aso )
i'd say go for apps2sd then if you need data go for that after

I now use data2sd with MIUI rom and a class 6 samsung sd card £16 from play.com
I would defo recommend this card, I didn't think from class4 to class6 would be that much difference I was wrong. I can now record videos without a single lag, phone is easy 10x faster and smooth, also MIUI is superb rom
Hi,
Most of the times a class 6 or 10 is much "slower" than a good
class 4 like the sandisk mobile ultra of 4Gb (The one of 8 Gb is slow !!).
The problem is that te typical test of writing/reading to/from a single file doesn't guarantee the behaviour of the card when used intensively.
When many files are involved, things change dramatically and a good memory controller is a must, and many of the class 6 /10
don't have one.

I have a 8gb sandisk class 4 in a stock desire and am getting 6.8 meg read and write when I test
What the title says basically. I'm looking to replace the 4gb class 2 sdhc card that came with the phone and get a bigger and faster one.
Depending on what the maximum size for an EXT partition is (I've read 1gb, other places said 2gb) I will chose between an 8gb and a 16gb one.
Coupled with that I have another question. I read that DATA2SD ROMs are generally slower that A2SD+ ones. If you were to compare an A2SD+ ROM using a class 2 sdhc card to a DATA2SD ROM using a class 6 card, which would you say is the fatest, most responsive?
Cheers.

Usually, size should be 2gb at max, 1gb is the general.
2GB is the limit for any rom before it starts to get a little unstable. 1GB is what everyone mainly uses but I have seen people with 1.5GB
IIRC by the guide I followed when I partitioned my card a long ago, it was recommended to have an ext of up to 1,4Gb.
1GB is ideal for the SD EXT
I have used 1gb also. (EXT4 partition)
Can I use a part of the 1.5gb of rom in the desire z/ G2 to make a swap partition?!
It's dangerous to the eeprom life?
Performance would be much better than microSD I think..

As far as I know such a thing does not exist, though like you suggested it may be dangerous due to data corruption (though if properly partitioned you can fix it)
On the other hand using microSD for swap has been nothing but good for me, it has significantly improved speed, cause it is only a couple hundred Mbs of data on the swap partition so it can transfer quickly and smoothly, also it's only used when absolutely necessary.
What class microSD do you have?

I have class 6 microSD, but I think it's fake (trasfering speed is 2 - 3 mbps).
I think that the most important propriety for a good swap is the access time.. but the problem is that I can't find a site where I can see the access time of microSD tested by someone.
I want to buy a 32gb microSD class 10 or class 6, but if I can't find the access time..
I find that mustang and samsung microSD class 10 are cheap..
BTW I would love to know if I can make the swap file in /data or in /temp.
Access time in ROM is a lot faster that in microSD.
I don't think that rom can be damaged by a lot of writing, so why I can't use that support for swap. It would not faster as RAM, but absolutely faster than microSD class 10.
PS: I tried to make swap file on microSD with swapper2 and cyanomod 7.1. I get an error on swapon.. does cyanomod kernel support swap!? Thanks

It should but for the life of me I have no idea why, I'm assuming you were just testing it out but if not, swap is NOT needed for most AOSP ROMs and could in fact slow down your phone and kill your battery.
Also swapper is not the most recommended way of doing it as if something gets corrupted there goes your whole SD Card.. :/ safer to make a partition on it.
As for speeds, the speed from the phone to the SD Card compared to the SD Card to the computer (through the phone/data cable) will vary significantly, and so will read/write times. For me through my phone I can read at around 15 Mb/s (class 10) and write at 3 Mb/s, but if I take it out and put it in a Micro SD Card converter then I can write at speeds of at least 10 Mb/s.
As for access time.. If I'm not mistaken, after RAM, SD storage is one of the fastest digital reading and writing in terms of access time. I have noticed no discrepancies in speed where it would have to read or write to my SD Card's swap so I think that'll be okay.
As for finding out if the ROM can be used... Quite frankly, not a clue, but I would tread lightly there if you want to start experimenting
i am thinking about the same question... Maybe it 's to be safe to use your sd card and make a swap partition. However i am on miui which doesn't require a swap so i don't have to use a swap partition. And the sense 3.5 and 3.0 are to slow and to heavy for me for the old desire z with a such amount of ram memory ..
My question is what app can i use to expand my Htc Wldfire S internal from 150mb to lets say 600mb. I have "m1ndh4x8r GB2.3.5|OCKernel|Stable|Apps2SD|DATA2SD|Premium Features[1/25/2012]" rom installed and tried data2sd but it lagged way too much. I had it 2.8gb Fat 32, 847mb Ext4 and 70.6mb linux swap.(could i adjust this to increase performance). I used a class 4 PNY 4gb card.
Any other apps that can do this that doesnt lag???
Thanks in advance
I don't think there's a way to expand the internal memory. Just use a microSD card with Link2SD and put all your apps into the microSD card. I'm also using a class 4 card and I feel that it works well enough. Think there was a fellow who was purchasing a class 10. That's crazy haha. I think the speed difference felt stops after a while.

Yes you can.Using data2sd i increased my internal memory to 687mb i think from 150mb. However it lagged the system so bad.
try sd-booster https://market.android.com/details?id=de.mehrmann.sdbooster and see it make some difference. I am using a class 4 16gb sd card without any lag.
Hi,
i have the problem of not enough memory OR a slow system. Currently im using a class6 16gb microsd with default app2sd from the rom (JB spazedog), but the app data fills up the internal memory nonetheless. If i move everything (not just apps) to the sd the system is getting slow and unresponsive.
It is worth getting a faster sd (class 10) and moving everything to sd or do i have no choice but keeping apps to a minimum?
Thx

No, but it would probably be worth to change to some rom which is not in beta and fits in /system small enough to have /data big enough to keep dalvik on nand and give more space for apps.
When using 6class and 10class i feel no significant changes in speed of app2sd area.
running speed test, write speed is usually about the same, read gives little higher results.

I'm using ICS Spazedog and DiskManager is working fine. Sometimes I have to switch pages when looking at app storage to get it to work. Maybe it didn't install properly, maybe your partitions need to be aligned, maybe the SD card needs to be reformatted. Could be quite a few things doing it.
Nope
Class 6 -> 10
If you use App2SD, definitely no.
If you use Data2SD, it is possible to see some differences.

In terms of memory, you have to keep in mind that using a2sd means sending the dalvik (if you choose so) ans the app to the sd-ext. While it allows to more internal space, it still decreases.
The sd-ext partition is practically limited to 1024mb by the desire inter storage size too, meaning that going over 1gb of sd-ext size wouldn't be better.
Now like erklat said, it is better to switch to more stable ROM as JB ROMs offer few space and their behavior have not yet been standardized.
Recap: In terms of memory, it is not necessary to change to an upper class, but it is always a nice harmless improvement.
In terms of speed, I have seen that changing to class 10 gives great speed changes in terms of massive gaming:
Due to the higher read speed and also with the read ahead bumped I was able to increase greatly the loading time of such games as Modern Combat 3 and Nova 3. I was surprised since I thought that it was because of the processor mainly that it was so slow. There is an increase in performance when switching to an upper class, but frankly you cannot notice it unless you benchmark the results by testing with a ressource eater app.
To recap: It is worth the change only for the read speed. I'm not sure but I think that write speed is somewhat limited somehow by the hardware. (I'm thinking about windows here, if someone could confirm that please. )
