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 )
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'd suggest class 10 honestly ...
I have a Kingston class 10 16gb and a SanDisk class 4 32gb and the class 4 SanDisk trumps the Kingston everytime, except during transfers directly from a computer. The SanDisk benchmarks much better also

The title of the thread specifically mentions booting, which means specifically running an operating system from the card.

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.)
Does anybody know if the Tab 7.7 can use a 64Gb Micro SD card?
Probably not. Most Android tablets only go up to 32GB

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 use 64 GB card and no problem.
Most manufactures says their devices is supporting microSD up to 32 GB, but really it's just a phrase.
I've tried 65GB microSD on my Galaxy S II and it worked then I tried it on my Galaxy S I also worked !! which made me try it on little Sony Xperia mini and also worked !!!
Just try it, Im sure it will work.
Yep no problems over here either.. Just need to format the card when it's in the device..

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
http://forum.xda-developers.com/showthread.php?t=1343164
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

Yeah, that's kinda what I figured.
I bought a Xperia Mini pro SK17i a few days back. It came with a 2GB memory card. I want to upgrade to larger space.
Please tell me should I go for 16GB or 32GB one. Will there be any problems? I mean any slowing down or hanging etc. Also tell me what class of microSD should I buy?
Im using a Class6,32G card on my mini,i think it's fast enough.
It matters how much space you need. Class 4 and above is fast enough for the XMP, not it is just your choice how much space you need . Im using Class 4, 32GB SD Card and I haven't got any slow or problem with loading my music or pictures.
I'm on a 16gb class 6, no problem at all.

Go for a 32 GB one if you think you'll be able to utilise the space. If you pick a class 6 or 10 card you really shouldn't have any speed problems. Obviously a higher class card is faster - class 10 FTW!
Micro SD Card Suggestion
Well 16Gb or 32GB is based on your requirements
My suggestion would be 16GBclass 4 or 16GBclass 6
I am using 16GBclass 6 on my SE Live With Walkman and it has no problem
for me
Class are based on their speeds
Class2 -->2Mbs
Class4 -->4Mbs
Class6 -->6Mbs
Class8 -->8Mbs
Class10 -->10Mbs
Use "Crystalbenchmark" to test the read/write speed of your cards
First check the read/write speed of your 2GB sd card that came with
your device and this help you to differentiate speeds of different class
types

These are only minimal speeds, these can be higher.
I have Class 4, Sandisk, 16GB, Write is 8.7 MB/s, Read 28.9 MB/s.
There's a thread on this subject somewhere here.
What you need to consider as well is access speed.
Higher class cards transfer faster, but to do so, data has to be accessedfirst, and that takes longer with class 10 than class 2 for example.
That means, if you are goinf to work a lot with larger files, it pays you to get a high class, if on the other hand, you are going to onstall apps to work with small files a lot, it will actually slow you down.
Edit:
I've found it, anybody interested should look at the tests results

There is a very good review here.
Which is best 32GB memory card for Neo V..
n is the Phone fast with 32 GB card or getting Lagged??
i'm not getting any lag with my 8GB (class 4) card. 32GB will do good
Let me give you an advice.
To the best of my knowledge a 32 GB sd card will need more power to work which means it will draw more power.
Also it depends from whom are you gonna buy it?
Sandisk? (if it is sandisk then BUY IT)
Also at the store ask for its class.
Just something about classes.
A class 4 card IS always going to give you at least 4mb/s write speed.
Although this is not always true.. (i bough a Kingston class 4 16GB for 8.5 euro XD and it is working fine but it mostly runs with 3mb/s it is slow but it was the cheapest and bigger)
The higher the capacity of the sd the slower random read write speeds.
So if you are planing to move many apps on your sd i do not recommend anything class 10 like.
But if you mostly need it for gaming/music/movies then for CLASS 10
Oh and always but sd cards from the web they are way cheeper than from stores.
(my Kingston from a shop costs 16Euro -mostly like every card 1Gb=1euro)
Buy a card with a high speed class.
Take min. class 6 or class 10.
Buy a card from a well know manufacturer like kingston , San disk or Samsung.
I use a 16 gb Samsung class 10 and the write speed is fantastic. 12 mb/s.

The answe is yes and no.
What 32GB ?
A 32 gb class10 sandisk wont slow it down.
A 32GB CLASS 4 KINGSTON WILL SLOW IT DOWN
it depends on the cards class and company.
a kingston class 10 VS sandisk class 10
would lose sandisk creates very fast sd's
If you are willing to pay a lot of money then buy sandisk class 10
IT WILL BE EVEN FASTER THAN WHAT YOU HAVE.
It depends on everything!.
Also android doesnt use the full potentional of the sd card.
You will need to root your phone and use an sd booster app to unlock your cards MAX SPEEDS!
For 32gb class 10 is must. Otherwise video recording, playing HD videos etc will lag.
I use 8gb class 10.
toshiba 32gb class4 no lags so far
Exchange of files between the computer and the phone affects the importance of speed
Class 10 is a must. Im using imation 8gb card. Images and videos loads and saves faster cmpared to lower class.

Previously used a transcend 16GB class4, the speed difference isn't that much, but you'll save a few minutes when making a CWM backup. (I went from 9 to 6 minutes).
