I currently have a 16gb sandisk class 2 card in my EVO. I have noticed that even on a fresh install, on a reformatted sd card that the gallery app is getting slower. Now to be fair, I am on Myn Warm two point two. I installed the Gallery3D from CM6 and it takes forever to load the thumbnails in both the HTC gallery app and the 3D one.
Also file navigation in ES File Explorer and Astro seem slower than they used to be. I know SSD hard drives need to be calibrated at times. Is it possible I need to format the car with different chunk size or some other optimization?
I have, for no logical reason since I don't store any music and only a gigabyte or so of video at any one time, been wanting to get a bigger and faster SD card. However, I recall that I initially read that these phones can't utilize higher than Class 2, but now I think about it that doesn't sound right. So if I buy a class 6 will navigating the SD card and loading pictures go smoother?
EDIT: I wonder, do kernels affect this? I am currently using "netarchy-toastmod-4.2.1-bfs-bfq-havs-more-smartass-universal (More Aggressive Undervolting)" but I am going to try the CFS version since my 1xx photos wouldnt load after like 5 minutes.
EDIT2: Okay it seems the CFS kernel fixed it. Though I did remove a good chunk of photos the CFS seems to stop bottlenecks that I suppose are from inefficient scheduling. A full backup with Titanium seemed to take a reasonable amount of time. ES File Explorer still seems to be slow at enumerating folders, but perhaps not as slow as it was, so my question about a faster microsd stands.
Would our phones benefit from this script?
Any brave soul care to try it?

Iq1d just to clarify a few things If we changed the cache to for example 2048 kb would that mean that the system would have 2MB of ram less? If so we could test other cache sizes for example 1024 that's only a 1 MB of ram and I would be willing to sacriface it for the sake of higher sd writing/reading speeds.
Here's one of the tests from the thread

I think it is worth trying I suppose it would speed up the devices of users who have data on sd card.
To gain extreme stability, we must use data on sd img/part.
If we can improve sd reading speed at the cost of 1/2 mb of ram, it would be worth it IMHO.
i really hope this works, as the only way to have stable data is on SD but the phone runs really really slow this way.
EDIT: I installed SD tools and ran it a couple of times, getting speeds of around 5mbps write/ 10mbps read on my class2. With these speeds my kaiser runs painfully slowly, wondering if the script will make any noticable difference.

Hm, could be useful for people who have fried NANDs ... *cough*
Though what really needs to improve is write speeds. Read speeds would be fine if /system is on NAND, but write speeds needs to improve as that's where our slowdowns come from.
On average, our Kaiser's SD Card reader writes on average 4.8Mbps, where it writes about 8-12Mbps depending on how much actual RAM is available.
Granted we could really use the increase in read speeds, but what good is fast read speeds if the SD card dogs down due to it having a very slow write speed.
ok, OC 480, data on sd partition. micro sdhc 4gb CLASS 2. Custom rom based on Gingerbones.
2048:
Write- 5.7
Read- 23.4
128(default):
Write- 5.7
Read- 12.1
4096: (OC 550)
Write- 6.1
Read- 11.5
hmm i tested this by just manual editing the value which resets after reboot.
4gb class2 card with no OC. sys on nand, data in partition using not so super froyo.
128:
write: 4.8 read 11.4
2048:
write 5.2 read 24.2
not sure if this improvement in read speed actually speeds up my kaiser. do you think a class 6 card would speed it up much?
not sure exactly how to implement it permanently, i tried manually adding a file but it didn't seem to work. though altering this value isn't too bad as i don't reboot often.
There's no caching on write aparently (probably to avoid lost data).
So writes must be mostly dependent on class + SD reader/writer driver.
Acording to wikipedia:
Class 2, 2 MB/s, slowest for SDHC cards.
Class 4, 4 MB/s.
Class 6, 6 MB/s.
Class 10, 10 MB/s.
(this is write speed, MegaBYTE).
So... either we are getting bogus results, or our cards are a little above the quoted class.

i think the classes are minimum speeds, and it seems other users are getting higher speeds than their class. how did you implement this script btw?
Read 1st post. Follow Link. Read whole 1st post there. There's a sample script there.
You must create a file in /system/etc/init.d/ named 99something_you_chose (should begin with 99, the files are executed in order, we should have our script run last).
So... either you remount /system with read+write permissions, and put the file there, or edit the androidinstall.tar and put the file there, or a androidupdate.tar with the file there.
Or...

hmm, drfno1, so do you have system and data on your SD card? is your kaiser quite slow then with write speeds of 2MBbps :S
i can't decide whether to buy a higher class SD card and if that will improve my kaiser's speed.
Been playing with this config only a few days with wifi only. My understanding is that the ext4 file system speed is what makes the system very usable. The only thing I find frustrating is the time it takes to boot and become stable. I say try it on your current sd first. The boost in reading seems to help starting apps and using file managers.

I don't like this sd tools app at all. It gives me some ridiculous readings. I have a 6 gig class 4 card with 5 GB fat32 partition, the app shows that the size of the partition is 4,2 gb. Also I get speeds of around 1.9 writing and 4.5 reading...this can't be right. I have just tried another app and the results were as follows writing speed 5.1 and reading speed 10, this seems more like it. Unfortunately after applying the script I don't see any changes in results still around 5ws /10 rs.
There is an app called SD Card Speed Booster in the Market.
Is it working for you?
I got it from 128 to 4096.
Maybe the gallery is a little quicker...
Have you tried this mod yet?
http://forum.xda-developers.com/showthread.php?t=1010807
It showed a little improvement for me. Run the benchmark program "SD Tools" to get your before and after.
Yup,big improvement. Flashed this morning & now my pic gallery loads almost instantly.
Sent from my HTC Vision using XDA Premium App
Both of those methods do the exact same thing - one just takes no memory to do. All they do it set the read ahead buffer to a higher limit. Next time you open something from the sdcard - odds are it's still in the memory so it loads from there without needing to wait for the sdcard. It *should* work for a2ext also so if you have a slow card (or even a fast one) things will become faster. Not sure if it helps with linux swap though (not that we really need it) - will some one with swap test this to confirm?
Okay I installed SD tools and this is what came out:
before.
write speed: 7.7 mb/s
read speed: 17.5 mb/s
after.
write speed: 8.8 mb/s
read speed: 17.5 mb/s
So only the write speed improved...
Setting update went back to 3072kb it was getting lagie at 4096kb 4/29/11
so it seems that 3072kb is the best for me anyway.
Settings updated to 4096kb 4/26/2011
remember to go slow with settings update so your phone doesn't freak out.
Pic one is 2048kb
Pic two is Quadrant test at 3072kb
Pic three is 3072kb
Pic forth is 4096kb
This I think is a better way is to just use

It is a two click app works excellent and noob proof start low and increasing day by day and you to will see how far-ging awesomely FAST your phone and apps work
I have mine set at 3072kb and when i open Media scape it's like instant view when i scroll my pics,music and videos and when i open Titanium and my camera,camcorder it's far-ging awesomely FAST and thats on a 2gb sandisk which is what you get thru att when you buy a x10a.
I recently bot a Wintec filemate mobile pro 16gb class 10 this has 1080p video recording capabilities. Tried to test my 16gb an 2gb cards with sd tools but its not working after last update???
SD TOOLS is working again 4/26/2011
Pics below is on the Wintec filemate mobile pro 16gb class 10
I will be going back to check the other settings in a couple days after i see how these settings work.
pics are after each reboot just to see.

I did as described but, SD tools did not show any increase in write speed (5 MB/s) nor read speed (14 MB/s). These are the same speeds I got before installing this app and doing the tweak to 2048. Am I missing something?
**EDIT**
I have a 16gb class 2 and before changing the value to 2048, I had write speed of 4.7 MB/s and write speed of 12 MB/s. So there was a slight increase in speed but, not by much. However, in my 8gb class 6 card, the read speed increased from 17 MB/s to 23 MB/s. So, I assume the degree of speed enhancement depends on your class of memory card.
try it now Thanks
lets try it
I'm trying with my Sd card 16 GB.. class.... i don't know...

When using the SD speed increase app make sure you set it to (set on every reboot)
and give it Superuser.
Set your values and click the flame button so that Status and Values read the same then reboot.
Yes Class and type are everything. The manufactures are finely figuring out that phone cams are being used more and more over the "Camera". Almost everybody now-a-days has a phone cam with them all the time. And are now coming out with cards that work better in your phones. The new class 10s that are being made for Phone/camcorders with high def and the speeds it takes to use them up to 1080p like the Wintec pro.
Also go slow with Value increasing so your phone doesn't freak.
So just start with 2048kb and go from there rebooting each time. And going to card each time an scanning threw pics,music,wallpapers,videos and such playing music and videos go to Titanium backup "if you have it" and scroll threw apps an check run Verify all your backups to see how fast it works.
Go slow with Value increasing like every 2 or 3 days until you have the speed that works right on your phone.
Also reboot after each SD TOOL test. So you get good test readings it will be a little different each time at first but soon it will com down an be the same.
Good luck

HUUM I searched the forums first but didn't find that. But it is a different app then
(DIEGO STAMIGNIs app) in some ways that it does stay in boot up and that it does work for me.
So sorry i did not see your post but i will post it in my forum on other apps that work if it's still available and be sure to give thanks to you.
Also i searched for that app (SD increase IT) in the market to post with Your forum post link but could not find it. I do think that this forum is for
Android App Market stuff ??? maybe not so sorry again i did not mean to step on any toes. just trying to post want works for me and to help others

My read speed went from 18 to 25 with the default settings. Lexar class 10 32gb. Write speed is 10mbs on average though it sometimes gets 15 mbs.
Sent from my X10a using XDA Premium App
Since source came out allowing kernel tweaks I've noticed some excitement over being able to move apps to SD card. I've never messed with this before but at the moment I'm in the process of moving my apps to my external SD card.
I've got a 32gb external storage and have about 20gb's left on it. My internal storage is low tho with about 2gb's left. A question I have is I believe I remember reading somewhere about some apps not running well off external SD.Is that a concern? Besides being able to move storage around......are there any other noticable pro's and con's that come with this.
By the way I'm running Dazed latest 1.5 with agats latest kernel running SmartassV2 overclocked to 1.3 using Tegrak. Where I work I have a terrible data signal/speed. After flashing the source kernel from Agat with a few tweaks I'm able to actually open apps I wasn't able to previously.
Awesome stuff.
[EDIT] Also, I always use Titanium Backup to restore my apps. Having apps on SD card..... does this effect in anyway I use TB afterwards.
Thanks
Never mind.... blackcanopy just answerd this in agats thread.
Mods you can close this.
I know that different SD cards have different read/write speeds.
A lower class is intended for lesser resource draining tasks; viewing single low Q photos, maybe listening to an mp3, or simply used as slow portable storage.
A higher class allows smooth hq photo viewing, video loading.
And the highest classes, class 10 and UHS(ultra high speed) are where you can store and view large raw photo files, and load 1080p video flawlessly.
(The latter, uhs, simply does it much faster, reportedly up to 40mbps transfer. However I am unsure if UHS is supported by the E4GT)
Now with all this, I'm not sure where reading applications may lie...
To speculate:
Applications (in my understanding) vary greatly with read/write speeds, between one another and within themselves.
At boot the app may have no issues, but as it progresses it may act upon higher speed requests, and if your SD class is on the lower end, it may not run smoothly.
I'm unsure where apps compare to SD cards, but I would assume that some of my apps would require high r/w speeds.
This is mostly speculative because I am unsure what the internal SD read/write speeds are, and how they compare.
My point could be moot.
Anyway just thought I'd share what I've learned on SD cards this past week, sorry op if it's no help!
