As far as I understand all SDXC cards will work

As with the N900 this only "officially supports" SDHC upto 32GB (only 16GB's were available on first release). This hasn't stopped me installing a UHS-1 64GB SDXC card.

I agree it will probably not be running at UHS but I have 64 GB storage none the less.

Hardware-wise, XC is HC. Wikipedia has more details.

At least the N800 does handle SD version 2 - so SDHC up to 32GB... and I think the hardware could in theory support XC - but not at higher speeds and possibly not without software/firmware support. I'd love to be proved wrong :p
There are some reports of working cards here.

Speed-wise, Nokia disabled high speed (either 24 or 48MHz) support in the driver as it caused problems with some cards (and I was also too chicken to re-enable for everyone in the CSSU), but there are simpe patches to re-enable it around for those who need the extra speed and know what they are doing.

(As a side note _ I have several USB adaptors that support SDHC, but really annoyingly not SDXC.)
That's because the SD driver runs on the embedded controller inside the adaptor and can't be updated :-(

Thats great! I've never owned an N800 but it's good for those that do.

Indeed I was just pointing out that HC support does mean XC will be supported.

N900 with 2TB (or N800 with 4TB) storage space is extremely neat to imagine, especially, that no reasons why it shouldn't work. Now, what those "new" devices without *SD slot will tell us?

Sure, it's a neat thought, right up until your brain gets around to imagining the part where you launch Canola and it begins indexing 4TB of audio files.

I have a couple of adaptors (MicroSD 2 SD) i just can't remember where i bought them, but yes mugen cover with normal battery or some special battery config then you can fit the adaptor in there, and then you got 128GB + 32GB (28'ish GB).

EDIT: found one

Nice find, but:

... supply cheap SD to MicroSD/TransFlash Card Converter Module ...
- Converts SD card into MicroSD/TF card
- Support SDHC
- Support card capacity: 8GB max
Not really tech-highlight, or? -but cheap- ;)

IIRC the whole "works with SDXC" thing is only up to UHS-1 (Gen 1 SDXC). The compatibility details after UHS-1 are sketchy at best (at the moment)

Re: Anyone tried 128 GB Micro SD XC cards?
 
I was just considering to extend my N900 storage capacity. So what is the maximum that should work normally? I thought it was 32, but on the official (?) data it says 16 GB; while here you're discussing even larger capacities.

Ok first off all, it is a direct connector so MAX Limit would be (with future updates) 999,999,999,999,999,999 TB
