Hi,
I'm just wondering if it would be possible to boot our ROM from sd card, so that we had more RAM and internal memory free? I'm not talking about dualboot.
I too was wondering about this!
I read somewhere that this was possible on the Xperia X10 mini, as far as I remember, at least a Class 6 microSDHC card was required else the booting will be very slow!
Doesn't anyone here have an idea on this?
There was an experimental data to sd that did this when we were using 2.2 rooms, but it was never very stable. I think the only advantage was to boost quadrant scores, apart from that you can do almost the exact a few thing with link 2 sd

whyy bother when we have so super-cool RAM. besides its wasting SD-card space.

Does it make full use of class 10 microSD cards ? or it caps them down to a lower speed ?
The reason why i'm looking for the fastest possible is that I am using Android and since it takes a while to boot I was thinking of using a faster SD Card to make it boot faster.
I am currencly using a Kingston 8GB Class 4 microSD card.
I could be wrong but Android boots off the ROM, not the flash memory, so the only speed increase you might see is in the initial loading of apps (like your home launcher, etc.) and that's only if you moved them to the SD card. as for there being a performance max on the HD2's ability to use a faster memory card, I'm not sure, but personally I'm using the EVO with a class 8 and I see a difference from my previous class 6.
Tnx for sharing, however currently the only way to use Android on the HD2 is to have it on the SD Card the ROM is still occupied with Windows Mobile.

Don't know how much will it cost.
Priority is card speed. Higher class is faster: http://en.wikipedia.org/wiki/Secure_Digital#Speed_Class_Rating
dont know the cost...my advice go for sandisk HC mem card class6 or a class 10...ur phone performance vl increase gradually ..
iam using a class 6 16gb my xpm is pretty faster than before.

Phone performance isn't affected by SDcard.
The only difference you can see is when you read/write files from SD, nothing more.
Web browsing doesn't get faster with higher class SDcard. Calling doesn't get better with higher class SDcard.
And Class 4 is enough for Android, I've never had problems with it and the speed is enough for me.

If you want to copy about 4 GB of data to SD from PC with class4 card and then copy same file/s to class10 card the time is a lot shorter with class10!
This is why many people use higher card class.
And when you want to have system in externel memory* this require minimum class6 card to avoid lags.
* e.g. HTC HD2
my Sdcard is 16GB class 10 (sillicon power) and write speed is 8 - 9 MB/s and read speed is 16 - 17 MB/s , this is very nice SDcard

I agree with u...but music player and video playback performance increases...and also after a reboot when u have apps installed in the sd it loads faster in the app drawer.

Hi guys
I'm looking to buy a Micro sd card, samsung 32GB, class 10
So my questions are:
1- If someone already using sd card just like this one, tell me is it working fine with your android device?
2- Do you think that patriot or some other manufacturer cards are better then samsung?
3- Does your phone in some cases really feals faster with an sd card with bigger class number ( does reading speed of your card effect phone's speed? )
4- I heard that class 6 ( 6 MBps ) is more than enough for android devices, and also that some class 10 cards slow down a device, is it true?
5- Will i ever have enough memory on my phone
I know that there are the same threads on forum somewhere, but i need answers quickly and thats why im opening this one..

1. It works fine.
2. It just user preference. Their both great.
3. Reading and writing to the SD card will be faster. It won't affect phone speed unless your device is using certain mods such as swaps, int.ext. sd swaps, etc. or you have apps on your SD card.
4. While class 6 may be quite fast for a device, there is no way a class 10 could be slower.
5. That's up to you .
tnx Theonew
if i understood it well, an app called swapper 2 can allow device to use some memory from partitioned sd card like a ram memory and provide it a slightly better multitasking, and speed.. ?
And i have read that it can also affect an sd card's life..
So, is it worth it?

Yes, swapping can degrade the life of the SD card but it is worth it if your device is a low-end one (and slow). It will assist in stuff like gaming, etc.
No, I really don't think its worth it. It really affects the cards life and does not really add much ram, even for slow phones...

An additional 256mb is quite a lot compared to 192mb (total).
Quick benchmark of Samsung SD card class 10 in the ASUS Transformer TF101.
Code:
[email protected]:/home/kuisma# hdparm -t /dev/block/mmcblk1p2
/dev/block/mmcblk1p2:
Timing buffered disk reads: 60 MB in 3.09 seconds = 19.43 MB/sec
Reference, the internal nand flash (/data partition):
Code:
[email protected]:/home/kuisma# hdparm -t /dev/block/mmcblk0p7
/dev/block/mmcblk0p7:
Timing buffered disk reads: 52 MB in 3.10 seconds = 16.79 MB/sec
If comparing read vs write, large blocks vs small, sequential vs random etc, the SD Cards wins a few times, the internal flash a few. It's more or less a draw. I would say this SD card got "good enough" performance, although far from SSD performance.
good enough for smartphone
are you talking about solid state disk?

Well, I just wanted to know what are the advantages and disadvantages of SWAPIT RAM EXPANDER. Cuz I am planning to buy it.
Some say it will wear out the SDcard. I'm in a dilemma to buy it or not.
Any suggestions ?

Question: Do you REALLY need more RAM? are you constantly running out of memory followwed by a "no free memory" error? If no: Then you don't need this app.
This kind of apps will wear out the SD-card pretty fast if you are a heavy memory user (Using lots of apps at the same time)
And the apps that gets "moved out of the way" will be a lot slower too. Sure, the currently running app might load a tiiiny tad bit faster, but thats it. Is it worth having all the other running apps slowed down to a glued-frozen-snail pace?
Check official link and opinion's
I don't think that you really need that, why don't you try to install ROM Toolbox, and set dedicated memory for some apps and decrease for others
Here Rom Toolbox Review
Suggestion!!!

well you can use that app if you have a class8 or class10 microSD card. the card will wear out only if you swap a bigger size into class2 and class4 microSD card. try swapper 2 in play store, it is good too and free. i have my sandisk 32 gb class10 microSD and i use swapper 2 to have more ram. my SD card runs well for about 1 year now. please press thanks button if i helped you. cheers..
I just have buy a brand new SanDisk Ultra Android 32GB SDSDQUA-032G-U46A of 32GB for my SE Neo V, it is ok if i use any Swap program to activate this function? How fast will perform the device when swap is on? My memory card is Class 10 UHS-1 30MB/s will wear out slowly if i will use a 4GB for swap? From what i know bigger swap file means less write cycles.

I use this program but I must tell You it doesn't make any big difference. I have sd card class 4, the program sais it uses up to 90mb of it's expanded RAM, but somehow I can't see a big difference in free memory. Maybe if You had some better class of the sd card, then You could use it, else don't even buy it.

hello everyone, im new and i have a question: i want to buy a memory card for my GT-I9300, but i dont which memory card i should buy, because i play a lot of games on my phone, like need for speed so i need a really fast memory card. so what will be the speed i need fo a memory card?
Sent from my GT-I9300 using xda premium
For speed, I recommend you keep games and apps on internal memory, and you can put all the songs videos, pictures on an sd card.
But is 95 mb/ps reading speed enough for large games?
(thanx for the answer by the way )

Look at the top of this thread for SD card info. It's sticky'd
keep games and apps on internal memory...that give you speed to launch them
