Increase The Reading Speed Of Your SD Card - Samsung Galaxy S (4G Model)

I saw this on XDA front page and thought this might be something that Galaxy s users would be interested in since the phone has so low internal memory.
I havent tried this on my Galaxy S because im gonna be selling it anyday now but hopefully this helps out.

This is great news!

This script does not work on our phones. Our ROM doesn't automatically boot scripts that are inside the init.d folder. We don't even have an init.d folder and even if you created it the script will not run on boot.
I'm looking for a workaround.
**EDIT**
If you download SD Card Booster from the market (https://market.android.com/details?id=com.vaelek.sdspeedboost&feature=search_result) it will do the same as the script and it will change the value on boot.
I confirmed this myself.

thanks... if my question gets answer

No. Just install it.
I couldnt run the script because I'm missing the /system/xbin/echo binary so simply bought it off the market (that app just run these scripts). instant reward. 9.5 write and 31.5 read at 2560.
That is, with the Vibrant's built in SD card. Don't have a tool to test the external card yet.

Hm. I'm not getting the same results using a 32gb card and the app set to 2048.

You have to play around with the cache size. The 'optimum' speed varies with each SD card.

Easier way to get apps on sdcard

Like always make sure you have a apps to sd rom. I would recomned haykuros 5.0.2 G r3 build with apps to sd.
I am not going to cover how to do this here as there is already alot of tutorials explaining this already.
First you should use a card reader and your favorite partioning program to shrink the fat32 partion and make a ext2 partition I would recomend atleast 100 mb. I used acronis disk director suite to make partition. Paragon or any other disk management program would work.
Once completed go download this www.tauruspc.net/scripts.zip
Extract the two scripts to your sdcard and then put back in phone.
Forgot to mention. These scripts move the data and dalvik-cache just FYI
Per other threads says sometime people have problems. But I have ran these on 5 devices with 3 different roms with no issues.
If this is the first time you are putting on apps to sdcard or that build
Download terminal from market and use these two commands
su
sh /sdcard/appstosd.sh
Once that is done reboot phone to recovery console by home and power button to turn on and then apt x
you should get a prompt then and use these two commands
mount sdcard
sh /sdcard/appstosd2.sh
If all goes well phone should restart and when if backup and running enjoy having all apps on sd and a permanent 73 mb free on the phone.
After performing these steps my G1 hangs on the "T-Mobile G1" boot screen.
What software are you running. And you need have apps to sd first with a formated memory card with an ext2 part. Because if you don't have formated card will not work. When you ran script did you get any errors?
script name
hello
the script down load as appstosd1.sh and appstosd2.sh and your post says the 1st one is appstosd.sh
I just rebooted the phone on the 2nd part, i hope this works :/
ive tried like 5 or 6 different ways and thus far none are working
[email protected]
If it works great but my advice guys if it ain't broke don't fix it, its already easy enough with all the tutorials out there.
Why not just use this app:
http://forum.xda-developers.com/showthread.php?t=504451
Install the APK and run the app. How much easier can you get? (Yes you still have to format your card but thats easy.

I am running 5.0.2G-A2SD, I have the sd-card formatted properly.. oh well, the I just followed the other tutorials out there and it worked flawlessly.
EDIT: Okay so I tried this again for the sake of testing, and I can confirm that it works. I guess I did something wrong the first time around.
quick question, do you have to leave the scripts on the sd card or can you take them off when your thru?

You can take them off.. they are just scripts to install the apps to sd. I can also confirm 73MB internal memory.. thank you for these wonderful scripts OP
EDIT: Hmm.. my browser does not seem to work anymore.
i'm getting an error "the process com.google.process.gapps has stopped unexpectedly."
also, tried a reboot and it hung on android screen for ever. did a wipe and had to re-do the scripts for appstosd, still receieving the error above.
Yeah I'm getting force close for anything I click on in the notification bar.
Ok can someone walk me through partitioning my sd card? I have Paragon Partition Manager 9 Pro, and when I delete the partition on my sd, it wont let me create a new one, and it always goes back to saying the whole card is partitioned as an FAT32 when it jus said unallocated
Thanks man. Worked great. Hopefullly I don't run into any future problems.

I don't have the link offhand but if you go over to androidcommunity I think you can do a search for a tutorial on how to use Paragon. Good luck.
i think you forgot to mention that a class 6 card is needed to move data/data over to the sd card
im using a class 4 card and when i moved data/data over to my sd card my phone would lock up without me doing anytihng. within 2 seconds of seeing the lock screen it would lag and then force close constantly.
i tried to move it numerous times. no luck
if u have a class 2 card dont even try moving apps to sd
and if u have a class 4 moving everything except data/data and dalvik-cache will be fine. ive moved my dalvik-cache over to my sd card and not that many problems. the ocasional force close but w/e
summary :-D
class 6 = only for moving everything over
class 4 = everything except data/data and dalvik cache
class 2 = buy a class 4 or class 6 card

[Q] Desire S, Changing SD card

My 8gb SD card in my Desire S is almost running out.. I have like 3.4 gb left. I'm planning to buy a 16gb sd card for my phone.. How will i transfer all my files, apps, games, also the save games to the new sd card? Is it only copy paste all the folder to the new SD card? Or i'll backup the apps? When i put the new 16gb SD card on my phone, i want nothing will change, like the same wallpaper, the widgets in the screen, etc.. except the memory of course. I don't wanna reinstall all of them again. Is their a way to do that? Thanks!
Yeah basically that's it .
'Almost running out'? you've near 50% left when you take in that you never get the full 8Gb due to system files etc

have you tried it, copy paste the folders to the new SD card? I heard some people are having problems like they had to redownload all the apps and install it. So, i'm just making sure nothing will change. Can you give me some steps on how to do this without having any problems? Thanks!

It's easiest and quickest to do if you have a card reader but ultimately all you do is copy all files from SD1 to SD2 (via PC)
Best to power off phone (ensure that you have settings->power->fastboot=OFF)
remove SD1
load SD1 into card reader
copy SD1 to a directory on PC
load SD2 into card reader
copy PC (SD1 files) to SD2
replace SD2 in phone
power on phone
nothing will have changed.
If you don't have a card reader then simply do then same but with the SD cards in the phone (mounting SD as Disk), worth Quick Formatting SD2 before you copy files from PC onto it so that its empty.
What if I'm on a custom Rom, like virtuous unity? Will it go back to stock after changing the SD card? And do I have to root the phone again? Thanks!

Sounds ok, although I don't personally know the manufacturer....
The size you want depends on the use that you give phone, if you watch movies often, listen to lots of music or are constantly flashing ROMS therefore taking backups, possibly consider a 32Gb card, I personally believe that you can never have enough space...on SD (obviously depends on budget).
The higher the class the faster/better the card
The current SDHC specification defines Class 2, 4, 6, 8 and 10 as follows:
Code:
Class Minimum Speed
2 2MB/s
4 4MB/s
6 6MB/s
8 8MB/s
10 10MB/s
1 1 megabyte (MB) = 1 million bytes
2 Based on SanDisk internal testing; performance may vary depending upon host device.
I thought I read somewhere on the forums that Desire s can't read cards above class 6 at their full speed ( could well be wrong on that).
The cards will work fine just the transfer speeds won't be as stated
Did anyone try this already? I'm just want to make sure that nothing will change, and i won't reinstall anything.. It's such a hassle reinstalling everything. My phone is rooted and on a custom ROM virtuous unity 2.37.. You guys positively sure that when i put the 16gb sd card on my phone, nothing will change? Even the widgets on the screen? I'm getting my sd card this week, so i just wanna make sure. Thanks!

As far as I know the card can't transfer at a rate above a class 6 card.Obviously it will accept faster cards but only read/write to them at a class 6 speed

EBay specials lol they work if you take all out of folders but no good for the likes of cmw

Also what format are they formatted in? .. because I believe they'll need to be in FAT32, not NTFS and not EXT4.

Have you tried with the latest kernel (JB version .25) and what make and model of your sdcard? just wonder if compability issue and are we talking about Micro sdcard or full size sdcard? On the full size there is a little switch on the side to block writting to the card.
I'm only having issues when I'm using the tablet to copy files. I'm on CleanROM Inheritance. I don't recall if I had this issue with the stock rom. Sometime tonight I will make a backup of my current and then flash to stock rom. Since I'm talking about the removable SD card, it could only be the micro SD that is installed in the tablet. There is no switch on that card.

Yes, it replaced what ever kernel you selected during cleanrom installation. Since it stock kernel, you can no longer Overclock.
Is there another kernel that can be the fix and still give us over clock?

Hi.
I'm having a problem with my Samsung Micro SDXC I (Class 10) card. I've been messing abut with it for days now, formatting, re-formatting in exFAT, FAT32, NTFS but the problem persists; whenever I try to copy data across to the card, the first time the card is inserted, it starts to copy, sometimes even up to 1.5Gb of data but often much less, but then gives me a 'Write Error' or 'I/O Error' message & stops working. Sometimes it also deletes other data on the card when the error occurs. then, until I unmount the card again, it barely functions at all!
A big factor in buyinh this tablet, unlocking, then rooting it was so that I'd have an awesome, small, tablet that had loads of storage & could be transported around very easily. If I can't get the cards to work with it, that's a big part of it's usefulness to me down the drain.
I tried to download the kernal that was mentioned above the message of yours that I'm replying to but the file has been moved. Do you still have it?.......or know how I can resolve my problem without it?
Any help would be much appreciated.
Thanks.

You don't say which rom or firmware you are currently using. Without knowing that I wouldn't go blindly flashing kernels that are nearly a year old
It could be that your card is actually damaged as I can copy files just fine on mine. I'm using a SanDisk Ultra uhs-1.

Hi sbdags,
Roger that
I'm not bad with most things tecchie but whilst I know which ROM I'm using, I'm not sure what the firmware is.
I recently updated to CROMI-X 5.2.2 from an earlier version in the hope that that might include an update or something that would solve my SD card problem.......it didn't
With regard to 'Firmware', I'm not sure where that's listed on the tablet but in the 'About' tab in my settings, it says:
Android Version - 4.2.1
Kernal Version - 3.1.10-g215ae8bf [email protected] # 1
Build Number - TF700 CHROMI-X 5.2.2 - 10.6.1.27.5 WW DEODEX
Pad EC Version - PAD-EC20T-0216
MobileDock Version - DOCK-EC20N-0207
I hope the firmware information you need is in there somewhere?
The card I bought is the latest 64Gb Samsung Micro SDXC Pro UHS-1 (Class 10) with write speeds of 20Mb/s & 70Mb transfer speed. I had read the formums & was torn between this card & the SanDisk 64Gb Ultra Micro SDXC (Class 10), the two-tone red/grey version, presumably like the one you're using but the Samsung was faster & at the time I bought it, the Samsungwas almost £15 cheaper. Since they were both reported to work, I opted for the Samsung card; maybe that was a bad decision?
I've just ordered the SanDisk 64Gb card, in the hope that that one will work because as i said, it really would be a shame if I can't make use of the extended storage that the SD crads give.
Do you use your SanDisk card in Micro SD form in the tablet or SD form in the dock.....or both......& have you got them formatted to exFAT or some other format?
Thanks again for your attention.

Hi sbdags.
I've tried using both the File Explorer that was included with CHROMI-X & another one from the Play Store that I use on my phone called Astro; the same thing happens with both. As I say, the card seemed okay to begin with but all I had put on it was my Nandroid & Titanium backups (approx. 2Gb total with lots of small files included). The problems started when I tried to copy a season of a TV series onto the card to free up space on the internal SD card. It started off okay & I wasn't expecting any problems but then approx 1.5Gb, I got an I/O write error & then all the problems I described in my first post.
As an aside, the card performed best when formatted to FAT32 but according to the SD Card Association, SDXC cards come formatted as exFAT, so that's how it's currently formatted; I thought if that's how it came & it initially worked okay, maybe that would solve the issue. Again, I was wrong!
So, I'll format it back to FAT32 again but as I've already had it in that format, I wouldn't anticipate any change to the card's behaviour.
The 64Gb SanDisk card should be here in a few days, so I'll be able to report on whether that one works or not then.
Did you have to re-format yours when you first got it or are the SD Card Association talking nonsense? Oh, & you didn't say whether you're able to use your cards in both micro form in the pad &/or full-size form in the dock? Also, was the Firmware information you asked for in that mass of stuff I listed. If not, where do I find it, so I know for the next time you ask
Thanks again

Hi sbdags.
I've tried using both the File Explorer that was included with CHROMI-X & another one from the Play Store that I use on my phone called Astro; the same thing happens with both. As I say, the card seemed okay to begin with but all I had put on it was my Nandroid & Titanium backups (approx. 2Gb total with lots of small files included).

I've never tried my card in the dock to be honest. Both my cards; 32GB and 64GB are SanDisk, I am not sure now what they cam in but I am using fat32 as I formatted them myself.
As for the stuff you posted I just wanted to know the rom and bootloader version. So CROMi-X 5.2.2 on 10.6.1.14.10 would have ben enough. Maybe the kernel helps too. In your case you are using the stock kernel. You may get better results on thatv4 kernel?

Cheers.
So, I think I've grasped that the kernel is similar to the BIOS on a PC; is that correct?
When you say that I may get better results using _that's v.4 kernel, what improvements are you thinking I might see?

Not really, the kernel is ... the kernel. The core of the operating system. Under Windows it's ntoskrnl.exe.
You could compare the bootloader with the PC BIOS - its main function (nowadays) is to start the operating system.

(q) REALLY, really slow reading/writting speeds at sd card

Hello, recently I have been having problems with my sd card and now I'm getting from 350 kb/s to 1.5 mb/s writting speeds (I'm copying a backup of my sd card and it's been copying for like.. 2 hours), so, anyone can help me?
I'm using CM 9.1.2 by Hehappy (THe first one he released, not the new one).
Thanks in advance.

Class of sd card? This usually indicated how fast the sdcard is. For example class 4= 4 mb/s read and write speed. The higher the class the faster ur sdcard

Have you tried removing the SD card from your phone and connecting it to your PC with a SD card reader? I usually get better speeds that way.

I have the same problem, I have a samsung class 6 microsdhc 16 gb, and i get write - 2.5 mbps and read 11-13 mbps
You could try with a class 10 (highest class) SD card. Or use a card reader. I've also read that if the port damaged or old, etc., so try putting it in another port. Maybe that'll help.

micro sd card LOW write speed

Hi ,
I have problems with my micro sd card class 10 (16 gb) due to low write speed (write speed should be around 10 MB per sec.). I have been using this sd card since my HTC EVO 3D without a problem.
With my SGS4 I never get more than 2 MB/s of write speed (transfering files from pc to phone). I was also playing with sd cache (I tried 1024, 2048, 3072, 4096) but still nothing (SD booster apk).
I att. also benchmark of my card (done with A1 SD Bench).
Thank you in advance.

my Sd card also seems to have a low write speed which is weird considering its the same 32gb sd card i had in my old s3

I am using window7 x64 so I tought maybe something is wrong with my PC but I did not find any solution on google regarding this problem. I had tried a lot of aapks for changig sd cache but without success - I can change cache but I get no difference in write speed.
how have you tested the write speed? If u just link the phone to PC and copy files from pc to the SD Card, it should be slow, because gs4 has no hard disk mode (I don't know if with some apps can make a real hard disk mode, I always copy big files with card reader).
If u want to test the write speed, try to copy a big file from interne SD card to the extern SD card, note the copy paste time and calculate the speed.
