[Q] Can you increase the data.img on evo to 1GB data storage?

ok just got a evo and thinking of making the switch officail from tmobile hd2 now on the hd2 android roms you can increase the data.img size to default 512 MB, 1 GB or in some cases 2 GB allowing you to install more apps on to your phone, I was wondering if the same thing was possible to do with the evo I like to have a lot of apps on my phone so if someone could point me in the right direction i would really appreciate it.

11 views and not one answer seriously someone has to know the answer to this and yes i have searched and found nothing

Forums are kind of dead on the weekends.
I haven't seen anything like that for the evo since it's 512ram/512rom.
We have apps to sd - basically you can move your apps to the SD card, which is normally bigger than the ram/rom.

Um, isn't it 1GB ROM + 512MB RAM?

Obviously you can't increase it its the built in Rom space.
You can use apps to SD (a2sd) on some roms that partitions your card and puts apps on it.

yeah sorry about that and I just know on the HD2 android which I have been using on tmobile you can increase the data.img size up to 1 GB which allows you to install way more apps on your android

that is because on your HD2, the data.img file resides on the memory card, which is likely 8GB or larger, so that increase in size is possible. On the Evo, the data.img is stored on the internal ROM, which has a physical capacity of 512MB, so we have already reached the maximum capacity...

if you wanna install a lot of apps i would recommend fresh rom's .i got 330 apps installed in my phone not on my sd cz for some reason my cheap ass 16gb card act up evertime i put an app in it.

Is your 16gb card a class 6? If not that's probably why.

^ FAST... Why do you say that.. Just curious because I was about to pull the trigger on a Class 6 16GB right now.

Those are the correct specs. They are the same that HTC, Sprint, and now Google have always advertised. 1 GB Rom and 512 MB Ram.
As to the OP, you may be able to change the partitions some, especially if you clean up the system partition, but it would require building a new ROM and flashing it. At least, that's the only way I know of to repartition your NAND.
Oh, and you probably won't recover way too much memory to the data partition. Probably no more than you free in system by removing some unnecessary built in apps like Quickoffice.

Becasue a class 6 card will be faster then a class 2 or etc.

I know this is an old, dead thread, but if someone is searching and comes across the OP's question, here is the answer.

Which to choose Apps2Sd or Data2Sd

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.

[Q] swap partition on eeprom

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 ..

Worth upgrading from c6 to c10 sd card

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.
attachment below 16gb Transcend 10class vs Adata 8 gb 6class

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. )

brother let me tell you something for benefit of your sd card
PLEASE PLEASE DO NOT USE SWAP
it kills your sd card
my 16 gb sd ard class 10 died during swapping
so if you have more money to waste and think you can buy one then go for it otherwise not
please thinks twice before swapping and i dont think 1 gb ram of grand is less then why use this
good luck

That RAM swapper will not work for our grand duos, mainly because we currently do not have a custom kernel (you need a custom kernel has SWAP support) for this application to work.
I can go into detail and explain how it works anyway if you like but the basic thing is, that application will not work on our sgg.
Try their second application - Memory Swap checker, to confirm what I'm telling you - https://play.google.com/store/apps/details?id=com.roehsoft.meminfo
I disagree with @aditya rathee about the dying sd card due to swap, if done right it works like a charm. I have used swap on several of my phones as well as this particular application on my Xperia J. It simply uses the empty space from your sd card to create swap file and uses it as virtual RAM for your applications to run in the background. Usually it is adviced to use Class 6+ SD card for these kind of things, but minimum requirement is Class 4. Personally I have tested it on Class 6 and currently using it on Class 10 SD card.

I'm not disagreeing with you on the fact that swapping decreases the life of the sd card. Yes, sd cards are made in a way that they have only so many read/write cycles, and using them for swap will essentially allow your system and applications to use that swap file/partition over and over again which would decrease the life of your sd card in the long term but NOT right away. You definitely would need to replace your sd card after a year maybe two depending on your usage but that's the cost you have to pay if you need more virtual RAM.
In your previous post you mentioned that your sd card died "during" swapping. That happening is very very unlikely, unless you had really bad luck or you were using an old SD card that had already been used a lot.

Is there any kernel with swap support for grand?

partition sd card
what if I partition the sd card let say i have a 64gb class 10 sd card and partition 60gb as fat32 and the remaing 4gb as fat32 also and use the separated 4gb for Roehsoft Ram Expander so that it will not affect the remaining storage encase the ram expander really kill sd card, would that be possible?

About SD Card Speed
I know this is a old thread but the user also asked about which SD card to use. I can't tell you which is best but I can give you the information so you can get what fits your needs. I too was confused about the markings on an SD card and did a bit of research. This is what I came up with:
Default bus speed 12.5MB Sec
High speed bus speed 25MB Sec
UHS-I (HC I, XC I) bus speed 50MB Sec
UHS-II (HC II, XC II) bus speed 312MB Sec
UHS-III (HC III, XC III) bus speed 624MB Sec
No speed markings minimum write <2MB Sec (Maybe SD Video)
Class 2 minimum write 2MB Sec (SD Video)
Class 4 minimum write 4MB Sec (SD, HD Video)
Class 6, V6 minimum write 6MB Sec (SD, HD Video)
Class 10, U1, V10 minimum write 10MB Sec (SD, HD, 4K Video)
U3, V30 minimum write 30MB Sec (HD, 4K Video)
V60 minimum write 60MB Sec (4K, 8k Video)
V90 minimum write 90MB Sec (8K Video)
32MB UHS-1, class 10, U1, V10 are approximately $15 (For a swap file nothing slower than this)
32MB UHS-2, U3, V30 are approximately $35 (For a swap file this is better)
32MB UHS-2, U3, V90 are approximately $75 (For a swap file this is best for under $100)
