Hi all, I heard that SanDisk has just announced their first SDXC card ever, a 64GB Class 6 microSD card that is designed for smartphones and tablets. While I don't predict that anyone would own one in the near future, I also predict that when people do get their hands on them, HTC probably won't have updated their handsets to allow compatibility with them.
I'm guessing a lot of people already know this, but I'm sure that quite a few of the people here don't quite understand why SDXC cards aren't currently compatible with our phones, like SDHC or regular SD cards are.
It's because once a source of flash memory, such as a SD card, surpasses 32GB capacity, it is no longer efficient to use the current standard FAT32 file system on them. Instead, they must use exFAT, which supports MUCH higher transfer rates and capacities.
Good news: the hardware used to read SD/miniSD/microSD cards with a FAT32 format is perfectly compatible with cards of the exFAT format.
Bad news: the software on the device that serves as the card's host probably won't be compatible with the exFAT format at this time.
Fortunately, from what I understand, this can be solved with a simple software update that shouldn't involve whole changes to Android. In fact, the ability to read and write in the exFAT format was released as an optional update a couple months back for Windows PCs.
What I'm asking is, for all devs out there, how difficult (and/or practical) would it be to implement the ability to read/write in the exFAT format in your ROMs? Or at least, could a mod be made that allows exFAT compatibility?
Hey just got my SIII and was wondering if it supports a 128GB micro sd card? I couldn't find any info on it so thought i would just ask here.
thanks for any info
i think the data-sheet over at samsung.com states, that micro-SD's up to 64 GB are supported.
i guess that some 128GB cards might work, but aren't officially supported.
Wow its great........

Ile get a 64GB sd card instead. Just to be on the safe side

I think all the devices that Samsung has produced all stated 32GB was max, but it turned out 64GB worked too. Let's hope that logic still holds when the 128GB is released!
Does anyone know when we will see 128GB microSD cards in the market?
Or perhaps there is a way to fit a full SDXC card into a microSD slot using an adapter and hiding it underneath the battery cover or connecting it using a thin laminate conductor that could be wedged through one end of the battery cover...
I'm not sure about any FAT32 limitations other than 4GB file size limit, but as long as the S3 supports microsdxc (which it does since it supports 64gb cards), it should be able to support any sdcard size.
I myself have a 64gb microsdxc card and have done a lot of research.
TL;DR: Galaxy S3 supports any size microsdxc card.

I'm not sure when we'll see 128gb microsd cards but I heard that sandisk developed the NAND. Hopefully Android 4.1 supports exFat (or does it already?) so we can actually utilize cards that big. The main reason to use a card that big would be for storing movies and TV shows, but any files over 4gb would have to be broken up first which is a PITA to do.
maybe in the future

Not yet!
This may seem like a random question, but why are 64Gb Micro SD cards cheaper than 64Gb SSD's. Are they not both flash? Does it have do do with the read/write speeds?
i wish

I wish 64GB micro SD cards were cheaper than 64 GB SDDs
on amazon 64GB SSD start from $60, 64GB micro SD cards start at $70
galaxy s3 on 128 gb
it is possible in galaxy s3.. with 64gb internal memory and support of 64gb on external memory.. but i dont know how much it will slow down the phone..
would recommend to use class 4,6 or even higher ones of mini sd card available for better results
Those aren't out yet......
Hey there,
The 128GB MicroSDXC cards have not come out yet so there's no point speculating early.
The Galaxy S III is stated to support up to 64GB currently, as that is the largest sized card out so far under the MicroSDXC banner. Once the 128GB cards are released, it SHOULD support those unless for some reason it has an artificial restriction imposed on it.
The other thing is, once the cards DO come out, people like NZTechfreak will check it out for us anyway. The cards should hopefully start to be released in a few more months. Definately agree on the speed class advice, go with a minimum of class 6 or 8, anything slower will be painful for sizes above 32GB.
And the Galaxy S 3 does support ExFAT by the way. I've currently got a 32GB card in mine formatted as ExFAT with about 4 mkv files that are between 4.5-7GB each.

PLEASE NOTE TEXT BELOW IS A COPY FROM WIKIPEDIA
"Compatibility with SDHC
SDXC host devices accept all previous families of SD memory cards.[26] Conversely, SDHC host devices will accept SDXC cards that follow Version 3.0, since the interface is identical,[3] but the following issues may affect usability:
SDXC cards are pre-formatted with Microsoft's proprietary and patented exFAT file system, which the host device might not support. Since Microsoft does not publish the specifications of exFAT and its use requires a non-free license, many alternative or older operating systems do not support exFAT for technical or legal reasons. The use of exFAT on some SDXC cards may render SDXC unsuitable as a universal exchange medium, as an SDXC card that uses exFAT would not be usable in all host devices. Since the FAT32 file system supports volumes up to the SDXC's maximum theoretical capacity of 2 TB as well, a user could reformat an SDXC card to use FAT32 for greater portability between computers (see below). FAT32-formatted SDXC cards can be used in a host device built for SDHC if the host device can handle 64GB and larger volumes.
SDHC host devices will not test the new capability bits defined for SDXC 4.0 cards. It will therefore not be able to use the new features of SDXC, such as transfer speeds above UHS104 (104MB/s)."
So reading that I would infer yes the 64GB or some of them could work in the G3 but may not work above that without formatting to fat 32, if I read it right that is

FAT32 supports 2TB volume size w/ 4GB-1B file size constraints.
exFAT supports 64ZiB volume size w/ 16EiB file size constraints.
I use exFAT, which the S3 supports, owing to my 1080p MP4s taking in excess of 5GB.
Since the S3 can use exFAT, we are well future-proofed to the extent of the microsdxc format I imagine.

Actually they state 64GB SDHC not SDXC. An many are now finding out they are missing files (songs) when they leave it ExFat. So chances are it may not support larger than 64GB cards. I to have a 64GB SDXC card that I have formatted with my computer to Fat32.
This is according to my manual (Canadian/American version). The European may be different.
By the time 128GB cards are released and actually at a mass production price, people will be talking Galaxy S4.
Hmm 128gb sd card seems like ALOT. I have a 32gb with my GS3, so 48gb in total. I have alot of movies,videos,pictures,etc. and I still have about 12gb left.

I'm pretty sure SSDs have more sophisticated controllers and such. Though according to Google, SanDisk's 64GB MicroSDXC card is on average almost the same price as the 64GB SSDs here in the UK (£40-50). Also, even the fastest MicroSDs can only support about tenth of the transfer rate of an SSD (although they are still pretty fast... the 64GB card is supposedly capable of up to 30MB/s, which is impressive).

You might not be too far off actually. I mean, folks getting excited about the new 5" display exynos 5 GS4 will be in full rumor mill mode around what, March? Granted it won't be released till summertime, but I'd armchair guess we'll see 128Gb cards pop up at the beginning of the year. They'll be $200 though lol.
i don't no, but i think no.
I want to use a bigger micro SD card slot because I store a lot of pictures and two gigabytes is not enough what are the available and highest gigabyte size card slot I can use and what class with no problems for this device LG optimus one thank you

32gb.
Everything higher would be SDxc and thus not compatible with our device
I'm using a class 4 card and feel it's sufficient. But since SD cards are fairly cheap in most countries nowadays, I'd choose a class 10 card. They just read and write way quicker (and can subsequently also be applied to enhance your RAM ).
Hi,
I want to install a new ROM in my TF700, with ROM2SD/DATA2SD and for that I am going to buy a Micro SD card.
The thing is I do really want to buy the fastest Micro SD card possible, but I don't understand the all variety of Micro SD card models/specs.
Can someone suggest me some micro sd cards (32GB?) that will be compatible and fast with TF700?
I have both the Scandisk Ultra UHS class 10 and the Samsung Evo.
I get better write speeds (and performance on data2sd) on the Samsung Evo UHS class 10.
The Samsung Pro also works well.
Forget those that promise 90mbs or more - IF the card actually gets that speed other than in an optimal test environment at the manufacturer, our CPU would become the bottleneck...
Make sure you buy from a reputable source and if from Amazon not the "frustration free packaging". It's disgusting how many fakes are sold out there....
