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. )

Hi all,
Recently, i have changed to Sandisk Mobile Ultra 16gb Class 4. Did a speed test on it with atto benchmark and it is able to read/write with an maximum of 19mb/14mb per second.
However, when app2sd+ is applied, I found that in certain apps or games, there is still an lag with the applications. (This is most obvious in games). If app2sd+ was not apply, such lags are seldom seen.
Thus, I feel that having app2sd+ is a great incentive for large storage but at the price of speed.
Are there any available tweaks out there that is able to improve the speed of app2sd+?
Pardon my poor english.
Thanks.
BR,

Yes, I suppose. I use a Kingston Class 10 microSDHC and I've never had such problems. I can move whatever I want to that card and cannot find any difference. Also, navigating across 300 images is very smooth.
But sadly, Class 10 cards are still very expensive, especially if you want 32 GB.
Would a Class 6 be good enough you think?
There must be something wrong somewhere.
I've had a Class 2 16gb Sandisk card since back when I had a G1.
I've used APPS2SD+ all the time on the G1 and used it for a while on the Desire until I moved on to Cyanogenmod.
All my apps run as tho they were installed on the phone, regardless of what people used to say about different classes.
I have some big games installed like Fifa 10 and Zenonia and get no lag at all.

i played caligo chaser on my desire.
this game has some obvious lag when i am using app2sd+. but show no lag when i install them on phone.
not sure is it because, it is writing to both fat32 partition of the SD card and ext 3 partition on the same SD card at the same time when it is running thus causing the lag.
Does anyone know at what speed is the phone capable of read/write to the SD card?

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.

Hello...
I have a SanDisk 4GB class 4 micro SD card that came with HTC desire. I installed one of those ROMs that support Data2SD, and it was fast without lagging (actually, super fast).
I bought a Kingston 8GB class 4 micro SD card to replace it with the SanDisk, and installed the same ROM, but I noticed an annoying lag during the normal use, as an example, just after booting to the home screen, when I enter Settings, it lags for like 5 seconds (that NEVER happened in the SanDisk 4GB card). It also lags on different application such as when launching the web browser (a pause for 7 seconds, and again, that didn't happen with SanDisk).
I bought another card, this time Imation 8GB class 4, but it gave me the same results as the Kingston!!
I did a test on the three cards using H2TESTW, the results are as follows:
SanDisk 4GB Class4 --> Write: 4.5 MB/s Read: 11.3 MB/s
Kingston 8GB Class4 --> Write: 4.4 MB/s Read: 18.3 MB/s
Imation 8GB Class4 --> Write: 4.5 MB/s Read: 18.5 MB/s
They all share the same speed in writing, but the Kingston and Imation are faster in reading! which confused me! They both have faster reading speed than the SanDisk BUT lag annoyingly during the normal use!
To be very clear, I tried the Imation card with a ROM supporting App2SD not Data2SD, and it ran smoothly with no lags, but once Data2SD is there, it starts lagging! (I know that Data2SD ROMs are slower than App2SD, but I swear, the Data2SD on SanDisk is FASTER than App2SD on Kingston or Imation).
One more thing, I tried various partitioning for the 8GB cards, with and without swap (swap was always 32M) but with no luck to improve the performance.
If anyone has a logical explanation for this case please let me know, and if there is a certain fix for that (I don't know if increasing the swap size for the 8GB due to their higher capacity would help) please share it here.
Thank you.
Are you by any chance using starburst? Try the newer xe and we scripts on the beta section.they should eliminate lags for slower cards
Swyped with my Starburst based Desire. Forgive any typos!

Thanks for your reply.
But it seems that the both of the 8GB cards that I have are faster than the 4GB card, then why are they slower in ROMs?!!!

Well, from what I understand, 4gb are faster in real life than 8gb, all proper tests show that, look up test charts in Google. I believe its because it takes more time to search for info over the larger space. I'm only speculating on that, as I don't know this for sure.

Well, that is what I thought of too, take -for example- 500GB hard disk drive, it will take much time to scan than a 120 GB drive, which is logic.
I will do more research on this thing and will post back.
Thanks.
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.
