I'm still running a sandisk 32 gig class 4 card. While getting ready for ICS I backed up everything, including copying the card to my PC. I noticed how much stuff is on it from apps and such, that it makes me question....
Does the microSD card speed have any impact on how the bolt performs? Will it be faster or have less lag with one of those newer Sandisk UHS cards?
The only benefit you will see is faster read write speeds to the SD card. You would probably have to increase the read ahead buffer to get the full benefits.

And that is part of my question.
I guess my thought process is... With the newer card having faster read/write speeds, I would think that any access the phone does of data/apps stored on the car might be faster. And with all the .Android_secure, android and other files/folders the bolt stores on the card (as opposed to internal memory), that isn't pictures or ring tones, I was wondering if it could make a noticeable impact on the performance of the phone or installed apps.
Has any one tried? Is there a way to measure or verify any improvements? I guess I'm looking for reassurance it will make a worth while difference before I go an spend money on another card.
As for the read ahead buffer, is that something that is easy to modify? how would that be done?
It in theory would make viewing pictures and stuff on the sd card faster. As for apps I'm not real sure. You can download apps like Rom toolbox that let you change the read ahead buffer but I think the thunderbolt maxes out at 4096. Anything faster will just default to that speed. To test it use one of the benchmark apps like antutu.

I know we have a way to move our apps to the internal nand memory, and that it's faster that way, but it seems like my class 6 sd card would be faster than the built-in sd. Is it possible to move our apps to the sd card (physical sd, not internal) so we do not bog down the system memory? It would just seem to make sense, until someone figures out how to make the internal sd respond faster.

We have 2 gigz of application memory.. No need for apps2sd... Not sure of the transfer rate on it tho... But apps2sd won't be as stable or fast... In my past experience...

^ Vibrant pretty much as its own dedicated space for apps.
The data storage is slow, and laggy. I don't think it transfers as fast as a class 6 sd card. I currently have my apps in my /system, but space there is limited. (did the stalling fix)
I'm thinking that my sdcard is faster than the internal sd. Maybe not as fast as the nand, but still.

umm?
I'm quite sure that the internal transfer rate is probably way above the capability of a class 6 for a whole lot of reasons, barring any manufacturing defects. If you are thinking that a memory card is magically going to speed up a phone that can basically do without one, then go get a UHS card to feel better.. . I'd rather just have a 16GB class 6 for storing crap and peace of mind but that's it.

NAND is faster than your class 6 card, easily... the lag is not due to the internal storage...
check this post. Maybe it will clear up what I mean about the speed vs space limitations.

I've used method 1, and noticed a HUGE difference in speed. If course, my sd card isn't going to be as fast as the nand, but in past experience (g1, mt3g) the sd card was faster than the built in memory was.

I did a test on my Vibrant internal SDCARD and it shows as a class 6....
I set CPU to 1000/1000 very little differences in battery drain yet did help a little with "lag" I also deleted most of the bloat-ware, startup and shutdown files...NOW ALL MOST NO LAG except as listed below...
When from 230 to 90 mb free after 1st boot up (without starting anything manually) to 230 to 120 mb free after 1st boot up...
So much Samsung has running at boot up so that extra 30mb and going down to 100MHz causes the"lag" - BTW, I did not do the "Lag fix" posted just to see if I could get it faster without going that.
The only two issue I currently have is:
While speednet app loads fast it will not start for about 45 secs - is forced to goto Washington State server, whereas all my other Android Phones goto CA...shows CA 1,123 miles away from phone
The double - "Press power button" and "then swipe screen" to use the phone is VERY "$$##%" ME OFF
I have used Titanium Backup to remove the bloatware, but I haven't tried permanently clocking to 1000. I saw no real difference in startup lag in my apps, until I used the "stalling issue" fix. What format is the data partition? That could have something to do with it? Would it make sense to add a swap partition to the internal sd? I'm really wondering if there are things we can do to tweak the built-in storage to make it more flexible, and functional? I would think 16 gig would give us PLENTY of space to play with...
My phone is just so...VIBRANT
Are you serious? I have well over 700 apks saved to my sdcard (almost 800mb) as backups... Theres no way you could throw that on an sd ext4 and it not lag.. Even a class 6... We can't even get apps2sd stable up to 2gigz... Like I said before the way it comes stock is faster and more stable than any hack we can come up with right now..

I'm having some serious lag on my class 10 32GB card and it takes like 10 seconds to load gallery. This started on the Ba2tf cm7 rom. It didn't do it before. I'm guessing the read ahead is below 3072KB. Otherwise I suppose I/O is lacking on the latest CM7 rom?
thanks
It took me 4 seconds to load the Gallery with a 32GB class 4 on Weekly 4, not too bad. It only takes half a second with QuickPic though and I like QuickPic better anyways.
I think you want SD Speed Increase from the market.

Thanks! On the previous build it was always instantly fully loaded. This class 10 card really performs excellent. It's a Wintec from newegg and I get about 15MB/s writing from windows 7. On smaller files it'll down to like 5MB/s but that's normal I suppose. Anyway I'm thinking either I/O rates are poor in the latest stable release or the read ahead it at like 1024KB. At least from my tests on my HD2, I always saw best performance and instant gallery loads at 3072KB, at least on my class 10 card.
I'll give that market app a shot. They usually have to be compatible with the kernel. We will see.
Thanks

yeah, performance seems poor when copying flac music files that are like 20-40MB per file say 1.5GB worth. I get like 5MB/s when on that last stable cm7 release I'd see up to 8-9MB/s on FLAC files writing from windows 7. I got up to 18MB/s write on big files and on the Ba2tf I'm getting like 12-15MB/s. I just wonder what happened to the I/O system on the ba2tf build over the previous? I guess I may be alone on this, or no one cares or notices a 3-5MB/s reduction in writes from windows 7. I'm running a Wintec 32GB class 10 card. I'll stick with ba2tf since there are a few minor improvements however there are some I/O rate losses so it's a hard choice for me. I'll reinstall the last build again and test it out and then compare.
Later
BTW - 3072KB seems to work ok. Looked like by default it was at 128KB?!?
Greetings.
I use a 8 GB Class 4 MicroSD card on my SGP 5.0 and while I'm listening to podcasts, which are saved on said card, and I start to do some other things, like browsing web pages, the whole system freezes and the only thing I can do at that point is to do a soft restart pressing down the power button for 10 seconds or so.
I'm thinking that the transfer speed of my MicroSD card is not good enough.
Since I have no experience with speed rates and classes, do you think a Class 10 card would solve my problem?
Thank you.
Sent from my YP-G70
I would rather say that maybe some apps had caused high occupancy rate of cpu ，since apps are commonly installed on internal sdcard.(This sdcard seems to be class6)
Probably the issue lays on read speed because I only have freezes when there's an app reading constantly files from the external MicroSD card even if that app is installed on internal memory.
Sent from my YP-G70
I've always used a class 4 card without issues.. I've also tweaked the SD card so it's hitting class 6 speeds.
Does the device even have the capability to use a class 10 card to it's fullest potential?
Perhaps you haven't had any issues because of your tweaks. I would like to try that for mine, so if you don't mind, could you share a guide or a place where I can learn to do that?
Thank you in advance.
Sent from my YP-G70
I use "SD Tools" from the market to test speed. Go test the stock settings and see what you get. Then I use "System Tuner Pro" to adjust the SD card cache size under the "tweaks". Change it, go back to SD Tools and see what your speeds are.
I've gotten the best performance around 1024, YMMMV.
Nice instructions. I appreciate it.
Thank you very much kind sir.

Not a problem! Good luck!
I apologize to all and sundry for being a noob, but must it seems post this here.
I have been testing GBX0C with the above phone on the 2degrees in New Zealand (GSM). I have found that the following odd behavior:
Adata 16GB class 10 & GBX0C = aprox 5 hours standby
Adata 8GB Class 6 & GBX0C = still going after 8 hours standby
Adata 16GB Class 10 & FRX07.1 = still going after 8 hours standby
To me this indicates some incompatibility between GBX0C and the 16GB SD.
Will logs be helpful to any one in this regard?
Other wise this is fully usable. Thanks to all those involved.
Battery usage is so random. Hardly anyone actually conducts a 'good' battery drain test - because usage patterns vary day to day.
Regardless, if your lower class smaller card gets better battery life - use it. Honestly the size of the card is probably meaningless, the class is more important here. I and many others have told people to stay away from higher class cards when using HaRET - there's no benefit, and you could potentially ruin the card. So why destroy a new fast card when an old slow one would probably work better?
Class measures raw speed, for sequential read writes. Operating systems use a lot of random read/writes, so you want a card that is best at that. In all my heads up tests of my cards, my 'classless' 2gb Sandisk card was the best.

Yes. I did read that thread, very enlightening. Just thought it was interesting that FRX07.1 did not seem to have the same problem with this particular SD.

Run FRX then? Not sure what you want me to tell you... You're comparing apples & oranges there as the kernels are different, and obviously userland is different as well.
There are several kernels for GBX0C. Perhaps you could try all of them, and see if one works better for you.

Hi, thanks I tried 3.3.8 and the same thing.
I have spent some time testing different cards, I got a 16GB sandisk class 4 (was the lowest class 16GB I could find on Trademe.co.nz) it also uses battery fast but is better than the ADATA. I have noticed some other odd behavior:
I have Identical copies of GBX0C on the 2 16gb and the 8GB SDs. I have been booting each in turn and comparing.
They each have a media folder with my custom Notifications & ringtones folders in them, at the Root of the SD. but the system will not show these on the 16GB cards, also "handsent" gives me an error when I try to set music as a notification "no music files or SD card not present" there is plenty on there.
The 8GB card has none of these issues. but it is alot slower.
I know I could just get an 8GB sandisk and it would probably help. and I know I can copy the media folder to the system folder.
I have attached logs for the 2 different sized cards they do seem very different.

Hello, so here's my question:
Is there a way to get the browser to do its thing using the external microSD instead of the slow internal one? Just like browser2ram does, but using the microSD instead of the ram. Or better yet, move the browser app to work completely on the external storage.
Browser2ram looses the browsers data with each reboot but if we used the microSD, data wouldn't be lost...
I dont want to move the entire system to work on the external storage since i dont wanna risk anything going wrong just want the browser... It would almost certainly remove all browser ANR's while improving speed (provided you have a fast microSD like I do).
If it is impossible with the stock browser, could it be done with any flash-capable browser out there?
Good question!

Data2SD is officially supported on Androwook 1.3 with the D2SD kernel. Plus the Rom is fast and responsive as all hell.
Well by modifying browser2ram it should be doable. Sources are somewhere on internets.

I see what you want to do. if you are unlocked you can use data2sd very safely if you do not do any further modifications to the ext4 partition. all of your anrs should be gone and your entire tablet will work better. There really is not much risk of anything going wrong as you put it. I have used it for the last 3 months with no data loss under standard conditions. where you increase risk is when you try to improve that performance even more by using ext 2 or non journaling ext 4 with data2sd.
