Ok so here's my problem,
I bought an 8gig band 4 sd card
Created a second partition 1 gigabyte big, more than enough for my apps linked about half my apps back with link2sd after restoring with titanium backup, but now my phone simply PAUSES and goes beyond lagg it actually does nothing then speeds back up (Normally this wouldn't piss me off but it just stops for periods over a minute and does this randomly and all the time)... Also sometimes while booting out would take ages and then just show a black screen... upon removal of the sd card my phone works fast again dip believing it was corrupted did numerous tools and stuff to check it and formatted it no difference and had it swapped at the shop...
However my replacement (Same sd card) is exactly the same
I've measured its read speed and its a crappy 10meg
So my is is it my sd card that's slowing down my phone (Guessing yes) and is there any way to speed it up/fix it?
I've now switched back to my tiny 2 gig sd card that came with my phone, and my phone has not had this weird problem...
(Read speed over 20 meg)
Thanks...

Btw I've tried apps like sd booster that increase your sd cache and increases your read/write rate but it barely increased write from 5>6 and read from 10>12...
Recommended if your want a faster sd card but in my case it didn't work

And for this you created a new thread when you already know you can ask it somewhere else. ?

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...

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..

Nevermind. Found a thread on apps to sd. It's already being done. I'll go check that thread. They don't see it as a pointless effort.
Thank you all.

I know a lot of people are still running SD builds and have not jumped on the NAND wagon<since it 's still not 100% stable.
Since the OS is running off the SD card, the card transfer has to be constant right?
So, is the life span of the card drastically reduced? If so, by how much?

OOOOHHHH thats a hard one.
Check this thread and decipher what you can.

thumbdrive (same technology - solid state memory) use for readyboost (constantly read/write as in RAM) will wear out after 10 years. that is, if you not using some "china" (not made in china -- "china") brand.
that is why they give lifetime warranty. by the time it worn out, nobody will want it if you put it on ebay.
this depends on many factors. mlc nand flash as used in all usb drives or memory cards has a limited number of erase/write cycles per cell.
typically this is about 100k now but can be as low as 10k writes
all flash has wear levelling and spare blocks the media can use to help stop cards going bad
read has no effect on wear
as phones dont spend their life writing data to the card they should last many years, but as with all tech, make sure you have a backup!
cheap unbranded cards from the far east should be avoided as they are built cheaper, will have less spare blocks and less sophisticated wear levelling
This is an interesting thread.
I use alot of apps, so even though I use NAND I have had to put data on the SD card.
After lots of corruptions and reformatting I resigned myself to getting a new SD card. Then used the Panasonic formatter to refresh the card.
However, yesterday my phone completely crashed and wouldnt make calls or run anything from the SD giving force closes etc.
Last night I flashed to MDJ Gingerbread on NAND without SD data so that my phone would work ( I guess this is the disadvantage of removing WinMo!)
So I think there is definately something in the lifespan of the SD card.

Hey i installed a custom rom, ewjet 008ex to be exact, it has an app called swapper configuration, at the moment its not active, ive never used it bfore but it seems to work very similarly to readyboost feature u find on windows. ive also heard that this can reduce the life of the SD card because the amount of read and write requests. has anybody used this feature and has it helped in anyway such as performance and memory usage, ny help would be greatful. thanks in advance
i've used it on CM roms on my G1 and it worked great.
i tried it on ewV008ex rom and i had some problems. i have an 8gb class 4 card, so that may have contributed to it, however, with 256mb swap, i would have a song skip every now and then, i had a few random reboots and bluetooth connectivity problems (not sure how that had anything to do with swap, but it started when i started swap and stopped after i removed it). and after about a day, i ended up with a damaged sd card (which ended up being a corrupt file somewhere on the SD card, a format fixed it). there was little improvement noticed, again, with a class 4 card. i really didn't test any other swap size because of how short of a time i used it. but i would assume with a class 6+ card, 128mb swap size on an ext partition on the sd card, and it would be a lot more benficial. too big will actually slow swap down, too small and it may not be adequate enough for your application.
there is no universal magical number that you can use with swap, the settings will depend on your sd card class, apps you are using, etc. typical swap settings are 64mb, 128mb, 192mb and 256mb, or atleast they were on the G1's a few years back. try a few different settings and see how it works for you.
Thanks for the reply mate, hmm in 2 minds buh i might give it a go, i have a class 10 16gb microsd card, so id have to create an ext partition i take it?
you don't have to, swapper can write the swap file to FAT
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.

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.

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.

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.

I did the changes and tests, this is what I got:
Before:
Read: 19.6
Write: 13.5
After:
Read: 29
Write: 14.1
Let's see if this solves my issues.

Not a problem! Good luck!
Hi, I bought xperia z2 and I'm really satisfied by it. But now when I put in my new Kingston 16GB class 10 memory card in it, at first it worked fine. I transferred by data in the card it was still working fine. But after a fewdays, when I opened my memory card, all the folders were named differently and had weird gibberish names. when I put the memory card in my laptop to check it, it said to format my memory card,I had a backup so I formatted it but it still didn't work. the memory card was corrupted I got it replaced but then after a few days same thing happened again. I can't understand why this is happening. I have antivirus setup both on my laptop and mobile and still my memory card was again corrupted.
Pleases help me.
I would be much thankful. (also I reseted my mobile still problem is there)
Have you tried with other memory?
xperias kill sd cards, it is a known issue
I can think of two reasons straight out of my head:
1: File system.
Most likely you're using FAT32 on the card, and that isn't a good fs for a flash-based storage. It will cause early corruptions with heavy usage.
f2fs, exfat, and even ext4 are better alternatives.
2: Too large sdcard cache size.
Cache size for sdcards are a popular value to increase in order to get better performance.
But it has a few drawbacks. One of them is an increased risk of corruption of the fs during shutdowns or reboots.
Decrease the sdcard cache size to avoid fs corruptions. Specially if one reboots often.

well, my Kingston 64GB works perfectly for a year first on Z3TC and since april 2014 on Z2 and never was broken. Maybe I'm lucky
