is there a way that one can use the space on the sd card as ram? just as windows 7 allows the use of a usb thumb drive to have as additional ram?
an app in the market called droidswap. that will do it for ya.
I use the swap partition from recovery but you can use a swap file also
does this make the phone run any faster?
yes sir, but can compcache is better
Using your SDcard will shorten it's life. Compache set to ~32MB to ~64MB would be your best bet.
using your sd card for swap will eat its brains!!!!!
Simple question which I did try searching for but was unable to find an answer to atleast in these forums....when setting up partitions on my sd card it gives me an option for a swap partition? Is this partition esseentially like virtual memory? Is it more beneficial to allocate as much as possible to this? I set mine to 128mb instead of the default of 32mb (I believe that was the default). Also set aside I believe 640mb for app space. (16 gig ridata class 6 mem card). Leaving the rest of my memory card availible for my mp3s/pics etc.
I always left mine at 32mb. Never had any issues using it. A lot of people set the swap size to 0mb.
currently there is a few lag fix out there;
- Real Fix by mimocan
- One Click Lag Fix ver 1, ver 2 by RyanZA
- CFLagFix by Chainfire
- A2SD FIXLAG (in SamSet ROM) by setenza01
- HKT Fix by ykk_five
Lets not talk about speed. This thread objective is to talk about the memory life.
Do you prefer to burn the life of internal SD or External SD?
Internal SD is definately gentle on the battery life but not the case for External SD.
And since Ext SD may have a better write speed.....
To weight these out, which have a longer warranty?
So which you prefer, lets talk about it.
If we assume that these kinds of fixes do have a noticeable negative effect on your SD card (with noticeable I mean that you'll notice it before you upgrade/sell your phone), the fixes using the external SD cards would be the best way to go in pure lifetime as you can simply replace the external SD cards should it become corrupt in some way.
There's been a few posts about regarding the negative effect of extX on the internal SD card, as far as I've read however it seems the effect is so low that unless you keep your phone for about 5 years you won't notice it.
Please correct me if I'm wrong as I'm not entirely confident with using extX file systems on my internal sd card either.
i like the fix that uses the External SD for this exact reason
External SD are cheap, and easily changeable
internal SD are not, so i'll only use internal SD for Apps that don't require much changes
I usually install all my Apps to External SD

I can gaurentee you all that all of you will switch devices LONG before something happens to either the internal or the external SD.
NAND chips are more durable than you probably think.

You know, it's easy to claim something like that, but if you would provide a source to that claim, it would be helpful for all.

That might shed light on the issue, and seeing as the article is two years old I presume that the nand technology might be even more durable in 2010.
I personally use the NAND fix since I prefer battery life (53h on and 23% battery left at the moment with moderate usage) and there is so much else that can kill your phone before the NAND stops working.
Guys, guys! The EXT2 fixes are just buffering data to the SD card! (This isn't the system NAND you're thinking of, either!)
Let's say an application counts from 1 to 10, and writes the value each time to disk.
Stock:
1 -> App tells RFS to write 1 to disk -> RFS writes 1 to disk -> RFS writes journal saying to changed the value on the disk.
2 -> App tells RFS to write 2 to disk -> RFS writes 2 to disk -> RFS writes journal saying to changed the value on the disk.
..
9 -> App tells RFS to write 9 to disk -> RFS writes 9 to disk -> RFS writes journal saying to changed the value on the disk.
10 -> App tells RFS to write 10 to disk -> RFS writes 10 to disk -> RFS writes journal saying it changed the value on the disk.
Total physical disk writes: 20. Speed: SLOW! Wear and tear on disk: HIGH!
Lag Fix:
1 -> App tells EXT2 to write 1 to disk -> EXT2 stores 1 in RAM.
2 -> App tells EXT2 to write 2 to disk -> EXT2 stores 2 in RAM.
..
9 -> App tells EXT2 to write 9 to disk -> EXT2 stores 9 in RAM.
10 -> App tells EXT2 to write 10 to disk -> EXT2 stores 10 in RAM.
..
EXT2 tells RFS to write 10 to disk -> RFS writes 10 to disk -> RFS writes journal saying it changed the value on the disk.
Total physical disk writes: 2. Speed: FAST! Wear and tear on disk: LOW!
This isn't exactly what is happening, but it gives you the general idea.

SLC chips last a lot longer than MLC....Thats well known.
But that all depends on if wear leveling exists... If it isn't somehow implemented, expect pain.
Do any flash memory-based devices not implement controller-level wear leveling? I didn't think that had anything to do with the file system. After all, most SDHC cards are FAT32 formatted, and before that, SD cards generally used FAT16. Those file systems were invented before flash memory was around.

just found this out
http://www.samsung.com/global/business/semiconductor/products/fusionmemory/Products_MoviNAND.html
We are consider quite safe, that the current MoviNAND is still based with 2bit MLC.
Can't imagine when we hit 3~4bit.
But do Samsung offer extended warranty for Galaxy S ?
iPhone does that.....
Going from the external sd fix to the internal ext 2 one seems to have improved my battery life

Guys! i might wanna ask something about RAM/Memory because it always gets higher, i mean sometime 167 default up-to 220.
is this normal?
and also i don't know what their been talking about SWAP PARTITION. what is that ?
i'm hopeless, NOOB!!!
Link to swap partition - http://forum.xda-developers.com/showthread.php?t=1659231. Swap is a way to use your sd card's space as ram. Instructions in that thread only.
About your ram, end all active applications frequently and delete system apps which you don't use often. In addition to this, if you use an external launcher, make sure it takes less space on your phone.

its normal.. try uninstalling some useless apps that is running on background...
DONT use SWAP it reallly degrades ur sdcard...

You can use swap with sd cards class 6 or 10, but not everytime.
I am using swap partition for 4 months, and my sd card is not degraded.
Hello, I recently got that app called Rheosoft RAM Expander for adding virtual RAM on my SD card. I works fine ( I added 1.5GB) but after a reboot, the app shows only 256 my is present. How do I cure it?
Dont use it. The mxp already have enough ram and using it, you will only notice a difference/benefit when you have an older device with 512mb or less memory. Also the more virtual ram (zram or swapp) the more battery it will eat. When using Kernel Adiutor you can easily change the zram size to 510mb if you like more virtual ram. Don't use a higher value or your phone will crash.
