Why not asking for SU after ReBoot!? (Here's explaing of the problem!): Thanks to GlossGhost

Lol, it really does something, Read: 4.5 MB/s

thanks good staff for my x10 i will test it later

---

the clock on the before shot shows that it was taken after the other

---

There's actually a new app called "SD increase " that will take care of the script for u

ermm... is there really a need to open a new thread when someone has already posted in our X10 General section where it should belong?
increase sdcard read/write speeds
anyway, good effort though...

Why would my write speed go up but not my read speed? In fact my read is slower than the write!

great find!!
before write 1,2 read 12
after write 1,2 read 13,8
nice!!

my results WITHOUT the script:
1 - Write: 3.2 MB / s Read: 12.1 MB / s
2 - Write: 5.4 MB / s Read: 13.3 MB / s
3 - Write: 9.1 MB / s Read: 14.5 MB / s
4 - Write: 10.1 MB / s Read: 14.9 MB / s
5 - Write: 11.0 MB / s Read: 14.6 MB / s
6 - Write: 10.4 MB / s Read: 14.6 MB / s
Now with the script:
Firstly, the script did not do anything!
Message from GScript "sdcardspeed.sh: / system / bin / echo: not found"
this happens because I have echo in the xbin folder
After changing the file "read_ahead_kb" manually to 3072,
1 - Write: 9.9 MB / s Read: 32.6 MB / s
2 - Write: 10.3 MB / s Read: 29.8 MB / s
3 - Write: 10.3 MB / s Read: 30.3 MB / s
Conclusion,
first we need to make 3 or 4 tests without the script to get the real speeds, and secondly, only the reading speed increased (is already good enough).
Question: How does "read_ahead" could increase the writing speed?

Okay, so I think everybody know's that when you turn on the phone, it's "Preparing SD Card" so the Script Manager is starting earlier than the sd card (i know the card is not starting but preparing). So the manager starts, and searches for the script, but there is NO sd card (because the sd card is preparing...) and what? Loading the script FAILS! That's why the manager don't ask for SuperUser permissions. That's why You have to move the "sdcardspeed.sh" to the INTERNAL MEMORY (I suggest moving it to the root folder of the INTERNAL MEMORY where are all the folders: system, sdcard.. etc) then you do all the instructions below.
Here's MY instructions:
1-Download and install "SD Tools" app that attached below and run to inform your sdcard write and read speed before applying speedup patch.
(attached @ first post!)
2-Download and install "Script Manager".
(attached @ first post!)
3-Download "sdcardspeed.zip" file and Move "sdcardspeed.sh" file into your SD-Card.
(attached @ first post!)
4-Use something like Root Explorer and move the "sdcardspeed.sh" file to the root folder of the INTERNAL MEMORY.
5-Run "Script Manager" search for the "sdcardspeed.sh" in the INTERNAL MEMORY not at the EXTERNAL MEMORY!" and select it.
6-In opened page: fill the "Run as Root" and "Run at Boot" check boxes and Save!
7- Reboot the phone and after reboot "Allow" superuser!
8-Run again the "SD Tools" and compare your SD-Card speed after applying the patch.

To what cache/buffer size does this script increase the stock value?
My sd has the fastest speeds with 2048kb...

---

Does this work for 2.1?
I've changed the cache size manually with Root Explorer and I've seen a huge jump in my read and write speeds.
The only issue is that the change I made goes back to default when I reboot my phone.
I've seen other MODs but it required for me to have 2.2, which is why I'm asking.

read : 11.9 mb/s
after:
write : 1.3 mb/s

something must be wrong... write speed 4x less and read speed 9x more
