[Q] Epand Internal 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.

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.

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. )

I think it is differ at the read and write speed of sdcard. Maybe it will effect the game, if you swap the sdcard. Then when it need to read data from sdcard, the higher class will make it faster. Just what i understand about that. Correct me if i'm wrong
Sent from my CM10.1 Wonder using xda premium

Class 2 is the slowest SD card speed. It had a write speed of about 2MBPS and is suitable for standard video recording. Class 4 and class 6 have 4 and 6 MBPS write speed respectively and can be used for HD Video recording. Class 10 (obviously) has a 10MBPS write speed and beyond that is the UHS speed cards that can go up to 312MBPS.

Speed Classes 2, 4, and 6 assert that the card supports the respective number of megabytes per second as a minimum sustained write speed for a card in a fragmented state.
You should utilize only UHS Speed Class.
Class 2,4,6,10 are laggy.

I disagree. Even at class 8, the sd card is said to be fast enough to be used as ram. Pretty sure anything you load from a class 8 and above card will be fast enough. UHS might be overkill (more performance than needed, waste money)
As for class 4 or 6,if the price difference is huge, just go for class 4. Put your programs on internal storage and stuffs that don't need high speed communication with your cpu such as pictures, video,unused files, etc can be placed in external.

Any benefit using Fastest External Memori Card

Hi, I'm considering buying much faster External Memory card for my Galaxy Wonder.. ( UHS-1 class 10 / extreme / super fast /etc )
but are they any noticeable increase in speed ( read music, photo, video, etc ) if I use that..??
are my Galaxy W even had capability to read such as speed that UHS-1 can offer..?? or it just a wast of money..??

I´m actually using a noname UHS-1 class 10 SDCard. It´s slightly faster than my Samsung class 10 SDCard, but this isn´t because of UHS-1 as this device doesn´t support it. It´s for sure a bit faster because it´s using faster NAND chips that are required for UHS-1.
So all in all it´s not recommended to replace an existing class 10 against a UHS-1 Card, but if you are planning to buy a new one and it costs the same, you can get a UHS-1 card as well.

so I assume it would be wast of money to buy A faster, even most faster SD Card, since this device doesn't support it..
May I know, what apps that you use to measure / benchmark the read write speed of SD Card..??
I'm using SD Tools and A1 SD Bench,, but I don't think that accurate

I benched them with Antutu Benchmark and there the noname was slightly faster. Just you will not notice this small difference in daily use.
So if you are already using a class 10 SDCard then it will be a waste of money, but for someone who is using a class 4 or class 6 it´s a good replacement.

From the 16GB to 32GB is there a speed increase/decrease?

Hmm, I'm using Antutu ver.4, but cannot see any benchmark for SD Card..
Yup, I already using class 10, so I guess I don't need to buy a faster one.

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.

sir it may have worked good for you but my sd ard was sandisk 16 gb class 10 i can send you its photo if you dont believe
also swapping increases reading writing cycles of sd card which results in damage

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.

I think the stock kernel does support swap becz if you enter
Cat /proc/cpuinfo you will get the following result and it features it says swp

Kernel with swap support?
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?

Hi,
Thank you very much for addressing the kernel for swap in i9082.
I was tired after wasted effort in search of this kind of stuff. This is working in i9082 with RR 5.1.1 lollipop.

anyone know about ROMs or kernel that support swap for galaxy tab 2?

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)
