Anyone try SDXC in N800?
 

There are now some 64GB and 128GB SDXC cards available...this is the successor to SDHC with more address bits. The current generation is electrically compatible with SDHC and just needs software changes (if that). Has anyone tried these cards in an N800 yet? The N800 has two full sized SDHC slots so it would be possible to install 256GB of flash, which is pretty awesome... the cards are quite expensive right now but of course they will drop.

it wont work... http://www.sdcard.org/consumers/faq/#sdxc_compat


Is SDXC compatible with existing SD devices?
Existing SD and SDHC devices are not be compatible with new SDXC memory cards, but existing SD and SDHC memory cards will still continue to be offered by card manufacturers for the foreseeable future. Existing SD and SDHC memory cards will work in SDXC devices.

Please see http://www.dailytech.com/Toshiba+Sam...ticle16972.htm

which says the current generation (SD3.0) is the same as SDXC, it's only the next generation that will become electrically incompatible. But that's a year old, so maybe the 128gb cards are SD4...

See also Wikipedia paragraph on SDXC.

Re: Anyone try SDXC in N800?
 

i hope they will be compatible but i doubt it will be and nobody wants to be a guinea pig for this thing as you can see theyre really pricey and with that money people rather buy something else...

The SD card consortium are either a bunch of incompetent fools or a bunch of money grabbing extortionists (or both). The original CF specs (1995) allowed for cards up to 128GiB. More than ten years later the SDHC specs (2006) modestly increases the original SD spec of 4GiB to 32GiB. The latest CF specs (2010) allows for cards up to 128PiB which is several orders of magnitude greater than that offered by this SDXC rubbish.

@kureyon, what SD Card Consortium? Don't you mean Sandisk?

Anyways, for chips that don't have an on-board controller, these sure are way more expensive than a USB stick with a built-in controller.

SD as in Secure Digital (not Sandisk :))

Re: Anyone try SDXC in N800?
 

SD and CF all have onboard controllers.

I think xD is the only contemporary card with no controller.

Re: Anyone try SDXC in N800?
 

The SDXC isn't a change in addressable areas, but a change in the size of the blocks transferred. Electronically, they're compatible. The issue is if the software (drivers mainly) is capable of adjusting it handle the extra data. Linux has had support for over-sized blocks (>512 bytes) for a long time.

Now the new fat format MS cooked up to put fat on these is another thing entirely. There is marginal support for that, both in Windows and linux. So that may be an issue. But if you want to slam in a 128G card and format it to efs3, the N800 should be able to handle that.

If you search the forums, you'll find a couple of posts from someone who already put a 64G SDXC card in their N900 and it worked fine. My understanding is that that part of the sub-system (driver wise) isn't that much different, and is one of the open components in any case. (SD tech isn't exactly trade secret stuff...)

Voltage wise, there's no way to damage a card from trying it. Just the data on it may be corrupted... so try it with a blank one. ;)

Re: Anyone try SDXC in N800?
 

It looks like the person with the n900 tested the 64gb card as a usb device with the n900 in usb host mode. The n900 only has a microsdhc slot so there is no way to insert a full sized sd/sdhc/sdxc card in the slot. The nice thing about the n800 is it has TWO full sized slots, making 256gb possible using 128gb cards. Today that would be pretty expensive but that situation will surely improve.

Exfat is apparently patented but Linux native file system are better anyway.

Apparently the current generation sdxc cards (SD3.0) are electrically compatible with sdhc but the next generation will be incompatible (higher clock speed among other things).

Re: Anyone try SDXC in N800?
 

I'll preface this by saying I'm far from an expert in the field, but as far as I can tell there should be no issue having SDXC cards recognised by the N800 assuming they're formatted to a compatible filesystem (and they can be formatted to FAT32 [if you use Windows like myself] with a bit of messing around).

I've almost convinced myself enough to buy an N800 and a 128GB card, because the utility would be beyond fantastic. If I do, I'll report back with confirmation.

Re: Anyone try SDXC in N800?
 

Good question. I tried a 64 GB SDXC (Transcend) in my N800. The N800 complains that the card is corrupted but won't format it. I think that the answer to the question is no.

Re: Anyone try SDXC in N800?
 

Do the same card work in a non-SDXC reader on a computer?

Re: Anyone try SDXC in N800?
 

That question is difficult to answer.

I tried on a mac with various SDHC readers. Sometimes it works, sometimes it doesn't. When it does not work, the mac complains that the file system is damaged but can read at least part of the files nevertheless.

The mac has a built-in SDHC reader which predates the SDXC specification, but the cards can be read just fine in that reader. The card can also be read in an even older reader from Transcend (manufacturer of the card).

So it seems that SDXC cards are electrically compatible, but that some new software or firmware would be needed to make the N800 able to read them.

Re: Anyone try SDXC in N800?
 

Disappointing, but I choose to remain hopeful. Would make the N800 have a very bright future as one's PMP.

Re: Anyone try SDXC in N800?
 

I have the Sandisk Ultra SDXC 64 GB card, and once reformatted it works fine in my n800, I formatted it fat32 and the whole 64 GB shows up in n800.

The only issue I had was on my desktop, with the first usb SD card reader from Adata(which I used because it was out), this reader wouldn't see the card as anything other than 32 GB in gparted or windows. I then used my older Sabrent reader which worked fine. Not sure what was up with the adata reader.

Re: Anyone try SDXC in N800?
 

Card readers need frequent updates; i.e. you'll have to purchase newer ones for newer cards (and probably experiment).

Re: Anyone try SDXC in N800?
 

Well well, that may well make mirroring the firmware to a SD partition more interesting.

Shows that the N800 may actually have a longer usage life than first expected. Perhaps i should just get myself some SDXC cards and clone the firmware onto the internal one. And maybe also start looking around for a new battery.

Edit: after looking at Norwegian prices i think i'll rather go with a couple of 32GB SDHC. This in particular as the SDXC will not be any faster at the transfer rates. Still, with a new battery and a 32GB drive for the firmware and programs this may have a long lease on life still.

Re: Anyone try SDXC in N800?
 

Indeed, I can't think of many other handhelds (let alone 5 year old ones!) that can be upgraded to 256GB internal storage today.

How about a (smaller, pricier per byte and harder to find but much faster and longer lasting) SLC for the OS & apps and an as-large-as-you-can-afford MLC SDHC/SDXC for media etc mass storage?

Re: Anyone try SDXC in N800?
 

That option would take some messing about with the soldering iron, and i own a N800 anyways so i have space for 2x full size SD cards ;)

Re: Anyone try SDXC in N800?
 

I meant smaller in terms of capacity, otherwise they are normal SD cards - no soldering or other hardware hacking required. Example (though I don't know it the N8x0's other electronics are capable of achieving the claimed 30MB/s throughput).

Re: Anyone try SDXC in N800?
 

Nuts, i should have guessed there was some kind of insane photographic sd card out there. But then i figured that all serious photographic gear was using CF anyways.

Re: Anyone try SDXC in N800?
 

I am wondering whether this will work with a micro SDXC in the N900?

Edit:
Great, it works according to this post: http://talk.maemo.org/showpost.php?p...1&postcount=19

Re: Anyone try SDXC in N800?
 

In essence, SDXC is seen as SDHC by card readers. The major problem is the file system, not the physical hardware. Pesky software patents...

Re: Anyone try SDXC in N800?
 

I just tested my 128 GB sdxc card in my nokia n800 and it works.

Re: Anyone try SDXC in N800?
 

^ Wow.

Thanks for posting this and welcome to our mostly dead forums. :)

Re: Anyone try SDXC in N800?
 

Thanks, the card I used is made from Lexar.

Re: Anyone try SDXC in N800?
 

a 64 GB Micro SDXC with SDXC Adapter from Sandisk works, too

Re: Anyone try SDXC in N800?
 

Can someone post links to these products so I know what to exactly look for next time I hit up Best Buy or something?

I think it's time that I go big too. :)

Re: Anyone try SDXC in N800?
 

I think any card should work. You will just need to format it, because Maemo doesn't have support for the silly filesystem they decided to use on SDXC.
