Help sd card speeds and apps2sd

[chrcol]

I have been looking into this and unable to find the answers I need, so would be nice if someone can help thanks.

My first question is what class is the included sdcard on the galaxy ace, I did a speed test on it using SD tools and I got 7MB/sec writes which is according to a page I found better than a class 6, yet people have said a class 4 card will speed it up.

Also what is the merit and downsides of using darktemors apps2sd script.

I discovered that every app that can be installed onto the sd card is done so by default, I noticed this as every time I unmounted the usb card they dissapeared and came back when I enabled the usb card again, I just found out how to move go sms pro eg. back to the phone memory. However after moving go sms pro to the phone memory it is laggier to use, but since its a sms app I feel it should be available all the time and I had to keep dragging the icon back to the bottom bar. So since gingerbread has built in sd app support and I can use it to move apps to and back what do I gain with dtapp2sd? Does dt-app2sd allow me to keep things like go sms pro internal so I dont have to keep dragging the icon back every time Iunmount the sdcard.

In regard to my sd card class, I took it out the phone but there is no number on the card itself.

I store all my stuff on my SD card and never had any issues with having to replace icons once the card has been removed and replaced

The only thing I can think of is cm7 cause I'm using the the lock desktop option but I'm sure I've never experienced it before ill take a look into it.

My phone came (3 weeks ago) with a 2GB class 4 micro sd card in India but some sites flipkart used to sell it with a 8 GB card some days ago.

and buying a faster sd card could speed up the phone?

 

[chrcol]

maybe, but hence my question, what is faster?

I think some assumed over the net the inclusive card is a class 2 which I think it isnt.

Class Rating 2. Transfer speed is a minimum of 2MB/sec.
Class Rating 4. Transfer speed is a minimum of 4MB/sec.
Class Rating 6. Transfer speed is a minimum of 6MB/sec.
Class Rating 10. Transfer speed is a minimum of 10MB/sec.

that would indicate the inclusive card I got is a class 6 and anything below that would be a speed downgrade.

Is likely I will upgrade to this.

Samsung 8GB Class 10 Micro SDHC Extreme Speed Card
or
Samsung 8GB Plus Extreme Speed Micro SDHC + SD Adapter - Class 10

no idea if they both different performance tho, one is white the other is black.

CWM backups 400meg a pop is my prime reason to upgrade at the moment.

 

[chrcol]

all done now.

I got the black card from amazon. On SD Tools its not much faster than the inclusive card tho.

These speeds are with cf-root with its default settings.

included 2 gig card unrated but I suspect its much higher than class 4.

7.4meg write
31.6 meg read

samsung extreme speed class 10 8 gig

8.2meg write (yes less than 10)
40.7meg read

When I copied files from my pc to the phone it was very slow kept stalling, averaged at 2.4meg/sec. But using the phone seems fine.

Here is a summary of what I have done since getting the phone to get to where I am now (using dtapps2sd) Very happy as this is much better than default way of moving apps as they stay useable when usb card mounted to pc. Also that all apps now moved instead of just a few. Still on stock rom.

If I can I will do a intensive guide as I know I needed one when I got my phone new.

Rooted using the update.zip from this site in the default recovery app.
Installed CWM via the default recovery app which gave me the enhanced CWM recovery mode.
Did a full phone backup using CWM recovery mode.
Installed cf-root b82-ex kernel using CWM recovery mode. This added CWM manager to the apps drawer, tweaks to the apps drawer and added the following support in kernel which will all work without custom rom, ext2/3/4, BLN, swap, different cpu governors.
Installed cf-root b82-ex fix patch to fix crashing gallery and 3d via CWM manager app.
did another full backup which can now be done from CWM manager it auto reboots int recovery mode for you.
In CWM manager installed ext4 manager, not used it tho but does allow converting internal filesystem to ext4 on stock rom.
Brought a new 8 gig sdcard class 10.
In CWM recovery again, mounted sdcard to pc, backed it up. Turned phone off, swapped in new sdcard, booted back to recovery mode.
Made 1 gig sd-ext partition on new sdcard and left swap at 0. It then auto made rest of space as normal fat32 partition for storage.
Mounted back to pc whilst still in recovery mode and copied everything back.
Back in the OS on stock rom I enabled DT-auto start in tweaks app.
Installed the cf-root dt-apps2sd zip file via CWM manager. It then rebooted and looped a few times, when it came back all apps that were already on internal memory were on my sd-ext partition on the sdcard, verified by titanium backup.
I then went into settings -> application management -> on sdcard, and moved them all to internal memory (which meant moving to sd-ext).
Verified again in titanium manager, perfect.
Did another backup in CWM manager.

I think my cache is still on internal at a guess.

Got about 5.8gig free now on the 8gig sd card with 1 gig allocated to sd-ext for apps. 140meg free on internal memory.
