SDXC memory

Does anyone have any information on the release date of the new SDXC memory cards? And maybe a possible pricing structure? They are supposedly being produced in capacities from 32gb up to 2tb in the same size format as the sd and microsd cards we all know and use regularly in our devices.
I've searched these forums using the keyword "SDXC" and I was amazed that there was 0 results.
At the las vegas CES it was announced that they were to be available at the end of 2009/start of 2010.
Along with my question on a more accurate release date, I was also wondering if these newer devices can be put into a raid configuration, or even be used as large capacity long term storage solutions? Because if they are mass produced for consumers then surely using 3.5" hard drives will be ridiculous when you can perhaps string several together in a raid making the combined size no larger than a stick of chewing gum. And with the right adapter make them excellent portable storage drives.
Is there a reason they couldn't be put in some form of raid?

Probably so, but there is a big chance that you will only see that coming out of someone;s garage than from a PC manufacturer. Think of it as lobbying... You have monster sized companies such as Seagate and Maxtor, which make these 3.5, 2.5, 1.8 in hard drives. They will do everything in their power to keep this new technology out of this possible solution. Potentially, you can save on:
*size of the PC unit as you already mentioned
*Power supply capability (since SD cards do not consume nearly as much power since they do not have moving parts).
*ease of repair.
*possibly price too, but that is somewhat far down the road at this point. Look at SSD
For our devices, you may not see it as it is likely not backwards compatible (think about when the SDHC came out)

Forget about using SD or any other non-classic SSD's in a RAID as a technology for data holding for three reasons:
1) Price. Look at current prices of 32GB SDHC cards
2) Quality. When you keep overwritting SDHC card all the time, it dies really quick
3) RAID and quality. With ^ only 1 card is enough to die and you lost all your data.
I still prefer classic 3.5" WD GreenPower for data and Black for system.

Yes i realise they will be extremely expensive. Thats the same with anything until the demand increases and it becomes cheaper to make them.
When they come out, they are mainly going to be packaged with HD video camcorders apparently. I guess that makes sense.
I'm still hoping someone can quote some rough figures and give an estimate on when they may be available to consumers.

For anyone who cares here's a bit of an update on the release timetable for certain size cards:

Android support micro SDXC (max 2TB) & FAT64 filesystem developement

Hi, I wan't to develop a new thing..
according to :
http://en.wikipedia.org/wiki/Microsd#Compatibility_issues_with_4.C2.A0GB_and_larger_cards
SDHC hosts which have drivers which recognize the newly used capability bits, and have operating system software which understands the exFAT filesystem, are compatible with SDXC cards.
currently (as Feb 2011), the Android doesn't have drivers to recognize exFAT (or FAT64), .... (or tell me if I'm wrong about this)
it's possible for us to insert SDXC card (more than 32GB) to the current SDHC host and recognize it.
but because my phone is Milestone (locked bootloader & signed kernel)
I can't test my own kernel directly to my phone. I need help other developers (who interested about this) to develop this thing ..if you wan't to contribute, then any previous work about propietary FAT64 file system is appreciated (sorry, must be open source)

P.S: sorry my english is bad, english isn't my native language

hello, anyone interested ?

I'd say try the question in this section: http://forum.xda-developers.com/forumdisplay.php?f=613
Sent from my Desire HD using XDA App

expanding on old ways
I don't know if this helps you but in older systems for phones you could fool the phones into thinking there where extra partitions to the cards, for example my palm centro capped out at 4 gig but i ran a 16 gig card inside it. I had to reformat the card from fat32 to fat16 or SDHC to Regularly SD and then was able to partition 4 gig spots, i had to partition becuase anything over the 4 gig limit would not be read. So i am curious to try a SDXC card in my fascinate and see where it gets me, but i have to wait till i get one of the cards. Otherwise it was a simple file mod and the card worked marvelously so if you have to partition 32gig sections that still a pretty large cap. Hope this helps you a little.

update: Apple has shipped new Mac with SDXC card slot
I estimate only take 4 - 7 month until HTC/Motorola will ship their new android phones with SDXC card slot

These cards are confirmed working in several Android's now:
http://www.androidnz.net/2011/09/sandisk-64gb-micro-sdxc-cards-confirmed.html

wow thanks, but it's new device
old devices still can't access newer microSD

Yeah if you want more then 4GB file size "exFat" currently not supported.
But you can still use SandDisk SDXC 64GB micro cards , just need to reformat them to fat32 , phone does it for you actually , talking from experience we had a long thread over at SGS2 forum section.
I have SGS2 and using Sandisc 64GB SDXC , upon insertion phone offered to format it as it did not recognize exFAT , after format it works just like any other SDCARD, max file size is <4GB under fat32.

Splitting SD card for internal and general storage?

Hi,
I have Moto 4G Plus, with latest Android. It has 16Gb internal memory which is not enough.
I bought good samsung SD card for 128Gb and now I have a choice
1) Use it as general purpose storage. Pros: Can copy movies, audio easily Cons: Cannot move apps, still not enough space,
2) Use it as internal storage. Opposite as 1.
Is it possible to split 128Gb, sd card and use 20 Gb as internal storage and the rest as general purpose SD card?
What would be the best strategy here? If I make it as internal storage, then moving and managing audiobooks, movies and music would be quite hard (maybe there is a better way)?
Also, I would prefer not to root my android.
Many thanks for all advices in advance.

You can do it using ADB shell (without root) or a terminal emulator (if you have root):

Thank you! It seems it worked! Only thing that it's showing unmounted sd card. But I guess I can live with it.

SD installed as internal storage, internal storage full, SD nearly empty, WTF?

I installed a 128gb MicroSD card in my Shield tablet and thought everything was setup, it formatted and encrypted the card to my tablet and when using a file manager app it shows one big honking storage drive, however when I go through settings I can see that my microSD card is barely touched and the internal drive is full, so full that I can't install anything else unless I delete something.
WTF is the point of having the microSD setup as internal storage if it doesn't share the install load?
Now I am trying to migrate data to the microSD card and I get the error that there is not enough storage space.
What can I do to fix this? :crying:

P.S. as an aside, could this be happening because the microSD card is a fake?
I don't think it is, but can't figure out why I am having this issue
I should add, I purchased this microSD
Lexar High-Performance microSDXC 633x 128GB UHS-I Card

Please XDA, you're my only hope

I don't think your SD is set up as adoptable storage yet. When it is it should look something like this:
This SD is set up as adoptable plus removable though, usually you will only see the adoptable part of it. As I will never fill the entire SD with "internal" content this way was better for me :good:

Interesting, begs the question, how did you set that up?
I just looked through my options, im not seeing it

Just looked it up, i followed those steps, my card has been formatted as internal and i moved data to new storage

Just formatted the card on my PC (the long way), then formatted as portable on tablet, restart, then format as internal, restart, then move data, and nothing has changed.
I am using android 7.

Not sure if you resolved this, but if you select the SD card the screen will switch. The 3 dots in the top right corner, then select migrate data. All the apps that can be moved will be moved.

query about memory card size

hi all,
i recently purchased infinix zero turbo 2023 , which has a micro sd card, the phone’s spec says it supports micro sd card upto 256 gb , i want to use 1tb micro sd card would that work, has anyone tried adding memory card higher than what the phone’s spec says , what has been your experience
thank you

Doesn't work: 256 GB is maximum.

I doubt you will find member that has tried, so just try yourself. check /proc/filesystems if exFAT is listed. as long as the phone supports the SDXC standard it may work up to 1 TB, as the address is within range.
0x3FFFFFFFFF = 256 GiB
0xFFFFFFFFFF = 1 TiB
the limitation is maybe just at time of writing the specs there wasn't simply such large SD cards on the market.
so it's tial & error.

No you cant, you can just use sd cards which is 256gb or less in size also if you want more storage try cloud storage

I'm sure it would work fine! Might need to format it first in Android settings, I used to have a ps3 with a 2tb HDD (supposedly not supported at the time)
Never use cloud BTW store your data locally so its literally in your hands not some stranger.

what basically allows you to format them as exFAT - a filesystem developed by Microsoft - and what can hold data up 2 TB.
Take note that it's up to OEM's discretion if they include exFAT driver in their kernel (and executables in userspace) after having an agreement with Microsoft or their partners. So check whether phone's Android can handle exFAT or not. AFAIK only some Samsung phones can.
