Going from a 2 gig SD to an 8 gig SD..
Is it as simple enough that i just make a copy of ALL the stuff on the original SD and copy it to the new one?
/EDIT- is anyone running an 8 gig SD with no problems, i heard its gotta be a class 6 or ill get unmounting problems?
If you don't use an ext partition just copy and paste your files.

dont buy class 4 sd card of any size. class 4 cards dont work with optimus one. they will keep unmounting. any other class or size card will work. aka class 2,6,10
the class of the card is determined by the clad number depicted on the card itself. a class 2 card will have the digit 2 written inside a small circle. same way with all other classes.
higher class means faster operation and probably more cost.

Since I keep seeing vagueness wrt exactly what the class rating of an SDHC card means, I'll spell it out:
Class X: guarantees MINIMUM write through put of X MB/s period nothing more nothing less.
i.e. read speeds can be anything as they're not mentioned by spec, latency can be anything again as not mentioned by spec, etc.
In the pre-SDHC days the VERY best uSD cards were those made in Japan by Toshiba(only manufacturer of uSD cards in Japan, might be re-badged but made in Japan is the giveaway). They maintained good read/write throughput and relatively low latency even when full. (All of those numbers tended to decrease as a uSD card became more filled.)
Made in Taiwan were next up. Passable, but no where near as good as Japanese.
Made in China bottom of the heap. I'd really only recommend using them if you had no other choice. Or could get by with R/W throughputs and latencies that were relatively poor and got much worse as the card became filled.
Also note there DOES exist a fairly rare pre-SDHC 4GB uSD card. I've never seen one personally but I know that they exist. Most were 128MB - 2GB.
Not sure if this still applies with SDHC as the controller electronics were changed and the min. write throughput spec added (mostly for video recording!).
All of this said I've got a PNY class 4 4GB uSD card that I'll have to try. The card is badged as PNY so I'm not certain who the mfg actually is. I'll see if I can't dig it up later IF it actually works correctly. (Only bought some of these since a b&m store actually had them at a close to decent price of $10 and they were suitable for my other devices.)
OK :|
Mass confusion now, i dont use a custom rom, so i dont need a partion, sweet will just copy across, im using a class 4 card now and its working fine so not sure what class to get, i thought it was just a problem with this fone that happened to ALL classes.

I have a class 10 sd card, but its made in china and its very low quality.. The read and write speeds are totally unpredictable. Sometimes i get read speeds of 20Mbps, but other times, i get 2-3Mbps. It is these kind of low quality cards that you must avoid. Good quality Class 4s will not cause an unmount.
Eg: Sandisk Ultra (Class 4) are way faster than Transcend (class 4)
(From what i have seen personally)
One more thing, it was reported that Android 2.2.2 fixed the unmount problem. So, incase you experience unmounts, you can even try using a 2.2.2 ROM.
I have class 6 transcenfld and it's super fast. Around 11 mb write and 20 read.

I think if u can find a 8GB class 4 Patriot microSD card... just get it... i'm using it and no problem at all... stay away from A-Data or Kingston cards... most of people that having unmounting problems using these cards.
PS. this problem exists just in Froyo when u partition your card to install programs on SD. if u don't wanna use this feature... or if u wanna use Mik's Gingerbread... take any microSD you want. but if u wanna use this feature i think Patriot Card would be better.
I use a Sandisk 4 GB class 4 card and still have unmount problems.
simple copy past is not working if you are using app2sd.
if u copy and paste u will have to reinstall all the apps but the data will be ok try titanium backup (did not tested titanium, but fkd up everything when i tried with copy and paste )
my newly bought 8gb class 4 sd card keeps un mounting so I wish to upgrade it to 16gb card.
so I want to know whether class 2 card will work properly or will I have to get class 6
Class 6 would be the better and costlier option obviously. I am using a class 4 16GB SanDisk card and havent faced any sd unmount issues till now. try using a different rom. i heard it mentioned somewhere that some rom's precipitate more sd unmount issues than others.
The class ratings for memory cards are like mpg ratings for cars. They are a measure of the card's read/write capabilities. The class rating doesn't tell you if you are driving a Mercedes or a Kia. Cheap cards with high class rating have high rates of failure and corruption. All classes of cards can work with your phone. Get a card with good reviews. Beyond a minimum class rating, you are wasting your money. My class 4 Kingston card has higher read/write speeds than my class 10 a-data.
I have san disk class4 8gb card and it keeps unmounting.
this cars is made in china.
I have another 4gb class 2 card of transcend and it does not unmount at all. this one is made in korea.
Transcend 8gb class 6 never unmounted once.

I am unable to find a class 6 card. all that is available is class 2 and class 4
I have a 8GB Class 4 card from Verbatim. It works flawlessly bro.
I have 8GB class 4 card and i had unmounts in stock 2.0 ROM and also in void rom. But now i am on Gyanogen 7 beta6 and no more Also A LOT faster.
Well I'm using 16g class6 from a small brand in Taiwan.But it works very well, with speed r11 w8.
I know it's not that fast, but very stable.
I guess unmounts depend on the ROM, whether you're using Apps2SD and the class. I had unmounts on void with Apps2SD. Quite stable with Cyanogen so far. Class 2.
Will upgrade it to a Sandisk 8gb class 4 soon. Sounds like a safe bet.
so you recon I upgrade my firmware to 2.2.2 from 2.2?
Target.... bestbuy... wally-world.... I got my sdcard from bestbuy just the cheepest 16g I could find... I have 3 partitions on it one being a 2gig ext4. Works flawlessly.

I try two Sandisk class-2 4GB and one Kingston class-4 8GB. All have problem daily. Eventually I settled on Transcend class-4 4GB. It not perfect (once a month maybe, I lost track), but doesn't both me anymore.
I thought there was a problem with class 4 cards, now I dont know which card works.

I don't think 2.2.2 solves the unmount problem. Try a cyanogen mod beta without apps2sd. beta 5 has been stable for me. I hope this will be fixed when the official gingerbread comes out. Create a nandroid and titanium backup just in case. the unmounts were the worst for me with stock lg.
I bought a Sandisk 4GB class 4 card and still had unmounts and freezes. Now my P500 is in repair service...
I had an A-Data 8GB Class 4 .. it was a disaster... multiple errors and reboots on installing program... very very slow. on all Froyo ROMs it was the same. but only on Cyanogen ROM it works without errors and reboots. also the boot process on Cyanogen beta5 takes about 3 minutes that i think it was because of that...
PS. I changed my Memory card today to a 8GB Patriot Class 4... I am testing it right now
PPS. Until now the new microSD works like a charm... no problem at all... it is so much faster and better than A-Data
doesn't divx videos stop working if you install custom rom? I use this phone only for four purposes,
reading books
internet
music
movies
I have a psp for games and another phone for phone and messaging etc
I dont have a computer though, so can't flash either.

I received my phone from LG repair service this week. They told me that they found nothing wrong, so they didn't do anything to the phone. Today my phone had again the "sd removed unexpectedly" message. It will probably have freezes again in a couple of weeks. These guys at LG service are useless. As my phone still has 10 months guarantee remaining, I will send my phone to repair service as many times as neccesary until they give me an acceptable answer or solution.
It's incredible LG doesn't have an official fix for this. Trying a different SD card is not a solution, since the SD provided should work, another SD is not guaranteed to work, and otherwise faultless SD cards are not working properly in this phone.
Hi!
I wanna buy SD card to my SGSII. Will my phone operate 32 GB SD card ? Does 32 GB SD card make my phone slower ? Which class of SD card should I buy ?

I have a SanDisk 32GB Class 4 MicroSDHC, works perfectly and doesnt slow down the phone.
I have watched 1080 video via MHL from the SD card.
Yes, 32GB is max. Open case so you can see what sdcard goes inside. No it doesnt make your phone slower, I think. But 32+16 GB is too much, so it might lagg a bit.

As long as the SD card has good enough random reads/writes it wont slow the system down at all (aka as long as its a good card its fine, aka the Scandisk ones are a safe bet, and actually the lower classes have better random read/writes).
The only thing is that if you have a lot of media the media scanner will take longer to finish (derr).
Thanks everybody, was also gonna ask the same question.
Nope. Sandisk 64GB micro SDXC works just fine with SGS2. However, I digress...
I concur with Veyka, my Sandisk 32GB/Class 4 works more than admirably for pretty much any/everything I've thrown at it so far. And they're fairly cheap too (<$50 AUD for me).

It's better to take some class 6 or class 10 card (but class10 is abit expensive and its almost no difference in most cases on SGS2).
The card will not slow your phone by itself, but a lot of files or media can slowdown mediascaner abit and increase battery consumption by mediascaner.
Just wanted to jump in with a reminder. The class rating of the card refers to the write speeds. So the class is irrelevant when you're talking about the performance of opening/reading files. The class is only relevant when writing to it.
That said, get a brandnamed card. I recommend Sandisk. I have a Class 2 32GB Sandisk that actually performs (from my testing) faster than a Class 4 rating.

Yes SD card classes shows minimum write speed (because before classes some manufacturers was "cheating" using "×" as read speed)
But read speed usualy almost equal to write speed. So reading from class10 card is for sure faster than reading from class 4 card. Just check this article on wikipedia. en.wikipedia.org/wiki/Secure_Digital#.C3.97_rating

That appears to be on a case-by-case basis depending on the card manufacturer.
From my own testing, my Class 2 32GB card can write at about 4MB/s (which is on par with a Class 4 card).
I also have a Class 10 8GB card which obviously can write faster than the Class 2.
But both of them are neck-and-neck when it comes to read speeds.

Cheers MB. I've been looking at them on eBay but thought class 4 may be a bit slow. Think I may get one now. For about $40 aud they are a bargain.

NP ;-) I paid a bit more than that for mine ($48 @ MSY from memory), so you're doing well if you can get one for 40 bucks.
I don't see the point of paying a lot more (double and more) for a card with a higher class rating for pretty much negligible improvement in "performance". We are talking about a phone after all, and this card handles 1080 video (recording it/writing it to the card) just fine which is probably the most "intensive" activity the phone is capable of.

Thanks for help guys
I have a Samsung 16gb class 10........ its the best card i've had... All i will say, pay a little more for a good brand, or your next thread you will be complaining about errors and sd card problems
For normal day to day usage in the phone there'd be very little difference in a class 4 or 10 card. However copying 32gb onto a class 4 card is a slow progress !! Spend the little extra and go class 10.

Didn't want to wait for one to arrive off eBay so a mate told me to go to Centrecom (Australia, Melbourne). Bought a class 10 for $50. Tests show write at between 10-11mb/s and read at between 18-20mb/s. Pretty happy.

Does anyone know for sure what Class rating the MicroSD card slot is in the Galaxy S III? Class 10? Class 8?
Thanks in advance for any and all replies.

Aren't speed classes for the microsd cards themselves and have nothing to do with the device loading them? Or are you asking up to what class will the s3 support?

I'm having trouble finding any nice comparison charts that are comparing the newer SDHC cards.
I'm considering...
Samsung MicroSDHC Plus Memory Card - 16GB, Class 10
Model#: MB-MPAGA/US
You might want to go for the fastest class you can afford. This way, when you plug in the sd card in your computer you will be able to load it up quickly.
I really don't like waiting to finish a 30gb dump of data due to a slow sd card.

Yeah just keep in mind the speed ratings refer to the transfer speed, not the internal memory speed which is going to be mostly the same for any type of card from how I understand it
Ok I was looking through the threads looking for exactly this...I'm getting a SanDisk ultra 32gb sdhc class 10 uhs 1 card for my s3 and want to get a second one for my son's fascinate...so this will work on the fascinate then, just likely not at full speed?
