[Q] SD Card Upgrade

I'm looking forward into upgrading my SD Card, right now it's the default CLASS 2 with 2gb. I pretend to buy a 16gb class 10 one, from Adata.
But I need to know some things first. The only reasons that I want to upgrade is to get more space to install apps, place musics and maybe expand my RAM a little.
So, is it possible to expand my ram? I don't want performance upgrade, it's just that I tend to multitask a lot of programs and my memory runs out really fast.
If so, how much more memory I can allocate on my SD?
Same for apps.
How much big can my apps partition be?
I saw that the recommended limit is something around 1.2/1.3gb, but is there a safe way to expand a little bit further? Or would it make the phone too much unstable?
And also, is it really worth it to upgrade my SD to a CLASS 10 one with 16gb? Or is it just a waste of money?
Thanks for the support and excuse me if I'm asking on the wrong section/way. I found somethings about it but there was nothing too much concrete. :/
EDIT
I just flashed my X8 with the latest firmware and baseband, as pc companion didn't want to install the baseband ..15 nor the newest drivers. Also installed the CM7, dualtouch and all that crap. It already installs apps to the SD and I've noticed a small slowdown on app startup. Would a class 10 sd soft it out?

Up to 200MB on SWAP partition, up to 2GB on apps EXT3/4 (any1 have so many of them???) rest for music/videos etc.

I have made a guide for partitioning the SD with ext+swap (you need AlfsKernel+GDX)
Look my signature

Thanks. But just another question. Is it really necessary to have a Class 10 SD card, or would Class 2 (the default one) slow things down while using swap?
Edit:
Also, a class 10 sd card is way too much expensive for me. I found a 16gb one, class 4 but it's SDHC. Will my X8 read a SDHC?

Everything above (and including) 4GB is sdhc, so yes, it reads them fine. About speed, yes it's important, apps will load faster.. but never amazingly fast. The X8 is slow nowadays, don't expect awesome results. If you are used to class 2 speeds and you buy a class 10 card then yes, you will notice improvement.. Not that much with a class 4. Do you really need a 16GB card? Maybe a 8GB class 8 or 10 would be better if you don't need that much space.
About adding more ram, just forget it

I got almost 20gb of just music on my computer, full discography of bands and all. Basically, 90% of the sd will be dedicated to music then But maybe i buy a 8gb one, i just need to stop being lazy and copy only the musics that i want instead of CTRL+A, CTRL+C, CTRL+V it all. Thanks for the help by the way.

So class 6 sdcard is enough for x8?

[Q & Discussion]Is SWAP really useless?

Lets face the facts guys. Our Galaxy Ace has very little RAM as compared to other devices currently on the market. Switching between apps is a pain in the ****. So I would like to ask is SWAP really useless as concluded by some members or its good for the phone. You can also list out experience with using SWAP & what kind of brand and class of microSD card you use here. I now personally do not use SWAP but I did b4, I have a class 4 32GB transcend microSD card that comes with life time warranty (I purposely put the warranty so I can also ward off those whom say it may wear out the card etc, what I want to find out is PERFORMANCE)
I search all over xda and all I got was some bits and pieces of answers here and there so was hoping to conclude everything right here in one place.

it makes the phone reaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaally slow. Happened to me.

it depends on ur swappiness setting (0~100)
set to 0 will disable swapping
set to 100 will make the system keep making cache and store them into your swap partition
*well, i'm still a noob, so just take my answer as a reference and if u want to know them more clearly, then ask uncle google
***
btw, too large linux swap partition is not needed, 32mb /64 mb will be enough for galaxy ace

If you use a lot of multitasking, swap will allow you to keep the apps data in memory for longer (no more reloading old web pages when browsing through lots of Windows)
It WILL SLOW DOWN YOUR PHONE, always (even with class 10 SD cards). The swap's new ram is much slower to read/write to SD card than the ram in your internal memory.
Swap will eat through your SD card and wear it out much faster. This isn't so bad with a life warranty and considering the low prices of SD cards. It's a pain in the nuts though, if you don't keep a regular backup of your SD card when the day it dies arrives.

I tried Swap with a class 4 SD Card, not really useful, so, I removed. You will try it if you have a class 10 SD

thanks for the reply guys

I would recommend swap only if you are a gamer. It will smooth out some games like nova or bia 2 or dead space or mass effect 3. Not saying that it will make the game lag free but it helps

Unfortunately not, to fix that you'd need to find the source of the leak and correct it

So what is the benefits of this fix?
Simply... Why we need this? Sorry but I didn't understand.... My bad mate

No problem The thing is, we have a certain amount of RAM at our disposal, plus our devices are getting faster and faster, getting more and more cores, but not that much RAM increase.
Let me illustrate my point :
htc HD2 (my frist device to run Android) - 2009
RAM : 448 MB usable
CPU : 1 GHz Qualcomm Snapdragon (single core)
SGS3 - 2012
RAM : 778 MB usable
CPU : 1.4 GHz quad-core Cortex-A9
So CPU speed is up by way much more than RAM, and I'm not taking GPU into consideration, plus storage speed increase etc...
Now those devices tend to be used in multitasking, having many apps running at the same time.
What those need is :
- CPU power to run on (we have plenty !)
- RAM to fit in (we have little)
Now even though an APP is running, not every bit of it is really needed, so those parts can be swapped out (put into swap) freeing these memory blocks and making room for more apps to fit in RAM.
So what will this mod do for you : Allow for more multitasking
Keep more apps running in RAM at the same time, making the device snappier when switching from one app to the other.
One app won't run faster !
If now you don't have swap, Android will have to gently ask the least used app to please close (save data, and quit) to free up RAM. Now when you get back to that app, Android will have to reload it, the app will start and reload it's data.
You can see, this will take more time.
Hope this isn't too confusing

I have a question before i attempt setting this up.
How do we identify which partition on the card is supposed to be for swap?
I have a 64gb sandisk card and say i make two partitions, one massive one for data and a 2gb one on the end for swap, how do i identify to android that the 2gb one is for swap? Also, what format should the partition be?
Cheers.

The script handles finding the partition
All you need to do is partition your card and be sure the swap partition is :
- a primary partition
- of type "Linux Swap"

I have 1gb micro sd card, so can i use whole card as swap card?

Yes, just create one partition with the size of the card, and make it a primary partition of type "Linux Swap".
But just a thought, what speed class is this card ? A too slow card might not be a good idea to use as swap device.
I'm waiting for my 64Gb card, so for now I'm running 512Mb swap on my older Transcend class 4 card, which is running fine for far. I'd not really go lower, though it's sur worth a try
JP.

Will the whole swap partition be used as swap memory?
And one more thing: what happens, if you remove the external sd, while the mod is active?

There's no mention what class it is. As i remember card came with some nokia phone 2-3 yerars ago, so i think that it's pretty slow, but i will test it anyway.

use with extsd and internal sd swap script?
Hi,
just wonder if I can use this with the extsd and interenal sd swap mod by mattiadj?
that will be great if i can use both mod and if we can use both, where will be the swap space? still the extsd?
thanks.

Hi,
Thank you for sharing this mod. What size would you recommend for the swap partition? I think that the general recommendation for desktop Linux is something like one to two times the size of physical RAM, depending on available disk space. Would that be reasonable for Android as well?

Swap will all be used, but they will have a priority (order) which you can check by typing "cat /proc/swaps" in a terminal.
I'd not use many though, you don't really need that much swap Just compare and keep whatever works best for you

On Android that might be shooting a little too high. I have a 512Mb partition, but I suppose 256Mb would be fine, that is the size I used on my previous devices.

[Q] HTC desire C storage problem!!

when i read at this page.... gsmarena.com/htc_desire_c-4759.php
at the storage it has "4GB include" but the device has 90MB rom and 940MB memory...
anyone please explain that
p/s this is my first post and i'm from vietnam, sorry for my bad english.
hello all you guy :good:

Welcome to XDA
I don't exactly know how it works but you only get around 1GB of space you could actually use!
Sent from my TF300T using xda app-developers app

Usuasable memory..
You are right. Both the websites and the box in which the phone is shipped shows the internal memory to be 4GB. But in reality this storage space is also used to store the phone's software. So the 4GB is actually partitioned into two parts, one storing the software and another part as the actual usable memory which can be used by the user. So you get a little less than 1GB of internal memory.. around 935mb or something. To know more.. go to HTC's website.

actually its split in three parts
1 part for the OS,sense,etc
2 0.94 gb for apps
3 ~90mb for storage (media,pictures etc)

so part 1 take for 3GB??

apparently ICS+Sense 4.0+bloatware=3gb
it's like the galaxy s4, from 16gb you get ~10gb of user storage
imo this is just a marketing scheme something like internet speed ads. they say "internet speeds up to 150mbps" not 18mBps(even though it's the same thing) because ppl like big numbers ;the difference is you still have the same internet speed while with the phone the 4gb mem is a lie ....unless you format the whole internal memory and use the phone as a throwing weapon....

and even though it has 512 MB RAM, we just get only 414 MB

Actually it is 512 or 414 mob of RAM..?

Our phone has 512mb RAM but the android system itself uses ~100mb so we get to use only 414mb

Even if you do that, there will be no performance gain. SD card is too slow for that purpose. Motorola did it the wrong way. They made a great device but didn't put in enough RAM to make it use its full potential.

You can root your phone easily... just watch this video
And using SD card as RAM is not a good idea, SD card is too slow to be an active RAM memory

You can use greenify and task killers to free up RAM. I know people say its not a good idea but it seriously works for this phone. It has too low RAM for Android to be able to handle it properly. It lags like hell without greenify and task killers.

I am using that workaround from starting. Even also sometimes very slow and don't respond, that time have to restart the phone.
Whatever the high RAM, after 2 years Android gets slow.
