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.)

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.

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?

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...

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.
is sandisk class 4 going to be recommended again?
On the Nook Color I've read the sandisk are usually the most stable and the class 4 was the most idea (even over higher classes.)
I was wondering if this is still the case before I spent 20$ on a 16 gig sd card.
Without a doubt. It has to do with sandisk class 2 and 4 cards providing random access to small amounts of data at speeds that are 10-100 times any other brand.
All the other brands are trying to make really big chunks of data write faster (think copying over movies faster) so I don't see anyone competing with sandisk here.
you didn't specifically mention what you were going to do. if in theory you plan on running cm7 on a sd card, then go with sandisk class 4. If you are only using it for storage and plan to run cm7 off of internal you can get a higher class rating for higher transfer feeds of large movies etc. unless you plan on running applications off of sd card where I think you would want the sandisk.

I saw 10 card in another thread (since deleted?) where someone posted about a sale on a 32GB class 10 card. Without researching the card I happily posted to the thread saying that class 10 sounded like a good idea as I like to write gigs and gigs of data (MP3s, videos) to the card for consumption. I didn't stop to think about random reads or writes nor did I consider other uses.
This same kind of info was then posted there. I removed my foot from my mouth and noticed that, yes, in most cases, normal people doing normal things (i.e. running apps, writing small files, etc.) will generally be more happy using a class 2, 4, or *maybe* 6 in their tablet. Save the class 10 for the high-def video camera that needs fast, sequential writes. Save the dough when getting a card for your tablet: do some research and pick the card best for you based off REAL-WORLD BENCHMARKS. (Save you some time - you generally will do just fine picking up a SandDisk card.)

Sd cards > 32GB is called SDXC cards. the smallest is 64GB. They typically come pre-formated with exFat which our phone doesn't support. You will have to use PC to re-format it into FAT32 using large cluster size before you can use it on the phone (the hardware of the phone supports SDXC cards
As I understand it, the phone supports SDXC.
Many 64GB SDXC cards are comming formatted as regular FAT which will work in our phone.
The SDXC standard officially calls out an exFAT filesystem - exFAT will NOT work.
What's with the class on the card never really noticed it what's it mean oh sorry for the thead hijacked...

Class rates the write performance of a card (in MB/sec). So a class 10 card has a write performance of at least 10MB/s (write speed varies depending on the size of data). Typically, cards read much faster than write (on average 2x faster).

Thanks. I read somewhere in another forum that someone was using a 64GB class 10 card formatted as FAT32 and got ~5MB/sec, suggesting that the format slows the card. My current 32GB micro SD gives me also ~5MB/sec (guessing its a class 4/5 without pulling it out), so a 64GB at 5MB/sec would be ok. I will get me one and report back. Just not sure yet which one. Sandisk? Samsung (haven't seen that one online yet).
Look what I just found:
http://www.engadget.com/2012/01/09/sandisk-unveils-worlds-fastest-128gb-sdxc-card-and-new-inand/
Class performance is only measured on a specific test... and can sometimes not be indicative of real-world results.
Sometimes people find that a Class 6 card does better overall than a Class 10, just due to being "better" in real world aspects other than what were tested for the class rating.
The class rating MIGHT only be raw write performance - the format of a card can have a major effect on performance depending on the underlying flash memory. For example, I recall a bunch of 4GB CF cards that got a HORRIFIC performance reputation at work - after further investigation, it turned out the only problem was that Windows defaulted to FAT32 on those cards, but FAT16 on smaller ones. The 4GB card formatted FAT16 was wicked fast.
My current class 2 16GB microSD card can give me 6MB/s write speed when I copy a small to medium sized file over. However, when I copy muiple or much larger files, the speed will eventually drop to 2MB/s. Most cards, especially cheaper ones, use a small cache to speed up the write performance and hide the slower flash memory. When you writes more than the cache can hold, the true performance of the card shows up. That's why a brand named card costs much more than no-name brands of the same class rating.

No, I'm testing it on my PC with 8GB of RAM directly. Don't trust phones for that task
My understanding is that most SD cards has a small block of flash cells that's much faster than rest of the cells. Small data chunks get write into those fast flash cells first before they write into the much slower mass storage cells. So, if you copy a large file into the SD card, you will see the write performance slowly drop as the cache fills up.

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.

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.

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.

Yep, same here. Stupid FAT32 doesn't let you copy files bigger than 4Gb though, so that sucks. Now if only there were some way to format the SD card using EXT2,3,4 or whatever, or get the Tab to easily recognize exFAT.
I did notice when i tried to copy a file from the internal memory to the external memory
It didnt work while i was unrooted. But since i have rooted i have not experienced this again..

I have 64Gb Kingmax MicroSDXC. Works fine.
Confirmed a while ago:
http://www.androidnz.net/2011/09/sandisk-64gb-micro-sdxc-cards-confirmed.html
My 64GB card has worked in every Android device I've tried it in, check that blog post for my list - also confirmed working in many other devices by others.
looking to maybe getting a micro sd card, not sure if i should go for the 32gb with price range of $30-$70 or fork out the extra money for 64gb, over $150. what would you guys recomend? and is it even worth it going for the 64gb at this point? i have the 16gb tab and using 16gb from original 7" tab.
Well.. currently the cheapest one i could find was at play.com and that's not cheap at all... can't we use the usb adapter and connect an external HD to the device?
I went ahead and bought the 64gb card ($152USD on Amazon) as I like to keep as much as possible on my tab. As far as a usb hard drive, I would think it would need to be on that does not need to be powered through the usb connection.
it works just fine, i have 64GB almost used up on my SGS2
In terms of whether the 64GB is worth it: only you can answer that. Mine is basically full and I would like even more storage, some people can't even fill an 8GB card, so it's quite a personalised thing really.
You can use pen drives via the USB adapter if that suits your use.
It seems from other posts that 64Gb cards are entirely satisfactory but my additional question is "What class is optimal?" There are Class 4, Class 6 and now Class 10 cards with price generally higher for the higher class. I note that another poster has successfully used a Kingmax 64Gb MicroSDXC which, I believe, is Class 6.
Does anybody know what the specs are for the MicroSD slot on the tablet. Obviously, it would be overkill and a waste of money if the device cannot read and write at the higher speeds that the card supports. Has anyone done any benchmarking?
I was considering a 64Gb Class 10 card for AU$125 but am wondering if the tablet can actually make use of it and a cheaper card would suffice.
the Sandisk 64 is a Class 6

I think when it comes to the difference in class, the simple explanation is the random access speed vs sustained data transfer speed.
Correct my current understanding if I'm wrong, but generally speaking, lower class = faster random access speeds, but slower sustained data read/write, whereas higher class = faster sustained read/write speeds, but slower random access.
Can anyone confirm or expand upon this?
that's why a Class 6 is just the sweet spot right smack in the middle of both
yeah Class 10 are faster to transfer huge files but slower on smaller files
and class 2 to class 4 are faster for smaller files but extremely slow for huge files like a 4 GB movie file for example
