Hi.
Is there a speed increase by installing a higher class SD card as internal SD Card?
Which class is the stock SD Card?
I did not notice anything and i replace the 2gb class 2 with a 4gb class 10.
Did you tweak the SD Card Cache?
I did not do any tweaks.

you can tweak it to 10240 cache ... not much notice but i do believe it has some impact especially when you are browsing using root explorer and the folder has many files in it...
How can i tweak the cache?
on dsc the cache (innersd0) is already tweaked:
/system/etc/init.streak.post_boot.sh:echo 512 > /sys/devices/virtual/bdi/179:0 read_ahead_kb
edit:
with
Code:
$ echo 512 > /sys/block/mmcblk1/bdi/read_ahead_kb
I got 2MB/s more out of /sdcard (tested with ales.veluscek.sdtools)

for longhorn ..
goto /system/etc ..
open init.streak.post_boot.sh
and edit the number something to like below..
echo "10240" > /sys/devices/virtual/bdi/179:0/read_ahead_kb
echo "10240" > /sys/devices/virtual/bdi/default/read_ahead_kb
echo "10240" > /sys/devices/virtual/bdi/179:0/read_ahead_kb;
edit the one that matches.. if not match, dont need to edit it... but you can play around and see what happen if you like...
Ok, to my shame i never knew that i had the tweaks it seams that if your using _n0p_'s kernel for miui, it's having all the tweaks.
Thanks for the help.
One more question about changing the SD Card:
In the tutorial it says it has to be formatted to ext3. Only ext3 or is ext4 possible too?

what the?
As mentioned in this thread:
http://forum.xda-developers.com/showthread.php?t=1867988
It says the Card has to backed up and then resized.
That means the Old ext3 is transferred.
Is it working with ext4 too?

If you want a 16GB card you have to follow deysmacro tutorial and TheManii, if you put a 8GB card you don't have to do anything.
This is a sd card test, the card is a class 10 samsung.
do you have a speed test with the original sd card as comparison?

the speed test for original sd card is of course the performance is much lower than that...
do you have a screenshot for me?

Ok, so I brought a new 16Gb Class 4 microSd card and I am going to partition it. I was wondering how much should I allocate to each partition type?
1. How does 14gb fat32, rest ext2 sound?
2. Should I leave any space for swap?
3. Also, out of Darktremor a2sd and Data to sd with dalvik-cache to ram, which one should I use?
4. In case if I upgrade my rom, do I have to re-enable them and copy the stuff again? Hows their compatibility with regard to upgrading?
5. Performance/drawbacks?
Thank You.
Also, does it make a difference which one is partitioned first?
Here: http://forum.xda-developers.com/showthread.php?t=1093317
It's mentioned that EXT2 is to be partitioned first but,
Here: http://forum.xda-developers.com/wiki/index.php?title=SD_card_partitioning
Fat32 is partitioned first.
make Fat32 first if you want sd card to be recognized by Windows... if ext2 will be first, you cant access second partition on the SD card...
What about Swap?
Guys I made the partitions as said but the phone says damaged sd card. But if I format by phone, it runs ok. Any idea?
Guys I ordered a new 8gb SanDisk class 6 card for my O1 so firstly I would like to know the things i should do to shift from my current 2gb card to the new one.
What are these partitions and how can I do that??
Will I have to reflash the rom after putting the new card??

If you don't know what the current partitions are, then the original card is probably one big FAT32 partition. Which is probably what the new 8GB one is. If you had partitioned it differently you would know it.
So the short answer is:
power off the phone
remove the card and mount on your PC
copy everything to a folder on your hard drive including .hidden files and dirs*
unmount the 2GB
mount the 8GB
copy back to the card
unmount the 8GB
replace in phone and boot
* you didn't mention what OS your PC is, so I will assume WinDoze

can u explain it a bit more?? Im not planning to use ungaze data2sd (actually i have no much idea about it lol but until now i have never used it so i dont think ill need it ) so then what should i do??
and yes I am using ur GTR so what would be the best partitions and how to do it??

Don't get yourself confused, just copy everything in your 2gb sdcard to your computer, then unmount it. Mount your 8gb sdcard and copy back the files into the sdcard and all is done
There is no need to reflash ROM, and no need to care about partitions etc since u don't use them anyway

> TAKE NOTE , before copying ur files to ur new sd, if ur planing to partition it.. partition it first.. why? cause your sd will be formatted during partition and all data will be lost..
> I already told how to.. just follow that procedure
What is swap and ext?? and what is the purpose of them??
Plus I use App2SD though...not any other special scripts

for SWAP google Linux Swap, but its basically a paging file for your phone in a linux environment, if you dont know what that is, google lol, but what it does is moves stuff on your Ram to this Swap thing, but android has its own methods, so Swap is only nessesary if you plan playing heavy games, and with apps like SWAPPER2, that you need in order to enable Swap on your phone, it can create a Swap file that just sits on your card, that acts like a partition without the hassle of you actually partioning anything.
EXT- they mean EXT3 or EXT4 which is a linux format, which in android case, you make your sd card into two parts, one the ordinary FAT32 part which is what you current SD card is, and another EXT part, on which with scripts, or even better LINK2SD, you move all your user apps 2, its similar to the APP2SD you use now, but it moves Dalvick cache and libraries, which APP2sd doesnt, so it saves more room on your internal phone memory, as you are actually moving the ENTIRE app to the sd card, say you want to move Angry Birds to SD using APP2SD, you will notice something like 5MB is still left on your internal memory, with LINK2SD it wont be left.
Also EXT partitions can not be seen by windows, so when you mount your phone as external usb drive, you can still use all the apps you moved to SD card, were is you wont be able to do that with APP2SD.
But yes in short EXT partition on your sd card, just splits your physical SD card into 2 virtual SD cards =)

Hi,
I recently bought a Sandisk 32GB Class 4 Micro SD card for my ST15i on ICS. I'm planning to move/link non system-related apps to it and store all my videos, music and pics into it. I've come across several threads regarding the issue at hand and this raised several questions:
1.) Is it advisable to partition it? If so, how and what would be the best method?
2.) How should I divide the space and what format should I use (FAT32, ext, etc)? Any rule I should follow?
3.) Lastly, which is better: link or to move apps using Link2SD or App2SD?
Thanks in advance.
1-yes, it's okay.
Download mini tool partition - Home edition
2- Fat for 2GB
Fat32 for 4GB or Above-----u should use Fat 32
if u partition the SD card ext size must be
128mb
256mb
512mb
1024mb ---don't use than 1024mb
3- I think link2sd is better, but app2sd also good.
What he ^ said. But to make a few adds,
You format the whole sd card as fat 32, and set a high cluster size value. Then create ext partition which can be made in fat32, ext2 or ext3 (ext3 is said to be best)
You can also partition the sd card from cwn recovery (remember it will wipe all data on card).
Linking is better because it moves a larger number of info onto the sd card, i use link2sd which is very simple and efficient. Nonetheless when linking most backup apps except titanium will not be able to follow the simlink to the apk (i think mbackup also just solved this issue but i'm not sure), but they will backup the app data.
Also be sure to tweak your sd card speed in case you havent already done that. A 1024 read ahed value should be the best option for your class

Thanks for the input, guys. I'm getting a clearer picture on what I should do with my new external storage. Now, let me ask a few more questions:
a.) Any particular reason why I should use ext3? Shouldn't the partition be both FAT32's?
b.) If I do use ext3, what would be the reason? Any advantage over FAT32? Also, is ext4 better?
b.) What should be the ratio when I partition my card? Ex. 50:50, 75:25, etc.
Again, thanks. I'll be doing my own research on the topic while I'm away.
1- u can use fat32 too. But ext 2,3,4 are better. If the rom support u can use ext 3 or 4..
2- ext3 is better than ext2 (correct me if i wrong)..yeah use ext4
3- for ext - 1024mb is enough
for ur swap 128
sd card should be fat32

As above guy said, use cwm
hmmm...the safest format when you want to partitions your SD card is FAT/FAT32....EXT2/EXT3/EXT4 is good but depend on your kernel...you your using custom kernel then those format wont be any problem to your phone....
here is the best way to partition your 32Gb SD card....
for your main storage/primary = FAT32
for your 2nd partition/primary = EXT2/EXT3/EXT4
for linux swap = you dont need this partitions so its an option....
Size for your main storage = the remaining size after you have partition it
Size for your 2nd partition = 1024mb (do not go beyond this size)
Size for Swap (option) = 100mb....

Yeah,
I've went ahead and formatted my SD card into one FAT32 and one ext3 partition (still thinking about ext3, though). I've linked my apps to the ext3 partition. I've managed to free up about 100mb+ in internal storage space. Time to clean up my system ROM, let's see how much free space I can get.
Thanks to Pusak Gaoq, bandarigoda123 and Rudjgaard. You've all been great.
Haha, no problem bro.
Hi all,
Does anyone know if it is possible to make a swap file on the internal SD card?
I have a 32GB internal but a class 2 16 external so this is my only option.
will it shoten battery life or general phone's memory/ productivity life?
anyone tried it before?
thanks!

If you want to have a swap file (swap.swp) this could possibly corrupt your fat partition. This is based on my own personal experience of course. I recommend use a swap partition honestly.
Just imagine mounting your sdcard to your computer to transfer files while your phone is still attempting to write to /sdcard/swap.swp. This can theoritically cause problems. And you don't want problems on your sdcard. A seperate partition is the safest way to go. But again... just my opinion.
NB: This mod will only work if the kernel you use has swap support built in !
Note that if you are using a rom based on Cyanogen's kernel it is NOT recommended to use swap at all. It will slow down your phone causing more problems than what it's worth. ('Swap grave' is how he put it.)

Many people would recommend "exFAT" file system, also some would recommend "FAT32" but due to the limitation of the file size, i won't recommend it, "EXT4" is good, but may not be a good choice for SDcard if you wanted to view the files on the PC using a "SDcard reader" one day, your sdcard then would be limited to read only, so you have 2 options:
1-format it as "exFAT"
2-just put it in the phone, Reformat the SD card with your phone Settings --> Storage/Storage & USB The file system on the freshly formatted SD card is the type that will give you the best performance with your phone.... in other words....(let the phone choose)

As i told you, Individual files on a FAT32 drive can’t be over 4 GB in size, but in exFAT it has no limitations, if it worked good for you in phone or pc then it's fine, if you faced any problems reformat it to FAT32.
