I got the 8GB ($39.99 Transcend) and the 16GB ($70 ADATA) from newegg (Both class 6 SDHC cards), I got them earlier this week and have had no problems with either of the cards nor do they seem to drain my battery any more before. You dont get quite the full 16GB after the card has been formatted but it is great to have close to 24GB's of storage in my n800. I highly recommend buying as much storage as your device is capable of as its so cheap. To prolong my battery I also picked up a Tekkeon Tekcharge MP1550 which is an external battery which is compatible with the n800, should take my n800 from around 3 hours of media playback to 3-4 times that!

Get the $16GB, its worth it for the price!

Good to hear that -- I just ordered 2 16GB A-Data SDHCs from newegg.com!

I'm hearing feedback that the 16GB A-Data gives 14.7GB, but still, that's 30.4GB, nothing to sneeze at!

I got one of A-Data card, and I see 14.95GB which is right for 16GB card b/c 14.95 * 10^30 = 16,000,000,000 Bytes, and that is 16GB.

I'm running 16 GB Patriot Class 6, and quite happy.

A couple points:
The difference of SDHC vs. SD is that SDHC uses different addressing. So an 8 GB SDHC vs. a 16 GB SDHC will cause no problems -- if it crashes on SDHC, it crashes on SDHC, not the capacity.

I don't know, not having done side-by-side comparison, but I know of no reason to suspect that a higher-capacity card would eat more battery, etc. How would it?

Reasons for 16 vs. 8: It's not that much more money, and saves having to move all your stuff to another card later when you fill it up. Especially with music or video, you can burn 8 GB pretty fast. (And map images, too, if you use maemo-mapper much.)

Hey, anyone of you guy, the 8G or 16G owners, you boot from MMC or internal flash? If from MMC, how did you do it? I can only clone to 4G SDHC card, saw several posts that failed to clone to 8G SDHC cards. Thanks,


bun

yes. I did it with my 8G SDHC.

I cloned the OS from the internal 2G SD (mmc2 for N800) to the external 8G (mmc1).

1. You go through the procedure of creating partitions.

http://maemo.org/community/wiki/HowT..._your_MMC_card

I did:
sfdisk /dev/mmcblk1 -u M (( for the mmc1 in M bytes !!!)))
0, 6000,0C
6000,,
,,
.....
and

# mkdosfs /dev/mmcblk1p1
# shutdown -r now

# mke2fs /dev/mmcblk1p2
# shutdown -r now

(( note blk1 !!!!!)))

You should reserve more than 1.5G for the ext2 if you want to load KDE later on. I haven't!


2. Boot from internal flash (not mmc1 or mmc2!)

3. make sure mbcache.ko and ext2.o loaded if not then load them


"lsmod" for checking and
" insmode .../2.6.xx-ompa1.yyy"to load
for 2008OS xx is 21 yyy either mbcache,ko or ext2.o

4. back up the OS from mmc2 to mmc1 (as root you do)

umount /media/mmc2 (umount if not we can not mount /opt)
umount /opt
rm -rf /opt
mkdir /opt
mount /dev/mmcblk0p2 /opt
mount /dev/mmcblk0p1 /media/mmc2 (re-mount so we can copy into it! )
cd /opt
/home/user/bin/tar -zcvf /media/mmc2/xyz .
umount /floppy
rm -rf /floppy
mkdir /floppy
mount /dev/mmcblk1p2 /floppy
cd /floppy
/home/user/bin/tar -zxvf /media/mmc2/xyz

Note:
1. umount, rm, mkdir : I want a fresh directory for mounting
2. /home/user/bin/tar is the tar-gnu not the one supplied by the OS. It came from step 7.1 http://www.internettablettalk.com/fo...ead.php?t=8631
3. you should have enough space on the DOS partition of the internal SD!
And there you have the same OS as in your internal (mmc2) SD!

Hope this help !!!

Thanks for the detail instructions. I may try it on a weekend. Why do you want to boot from ext SD rather than int SD? Any advantage?


bun

Actually the above procedure is used to clone the internal SD into the external one.

After it is done you can swap them ! But really why not to have an option of booting off from the external SD ?
I do
have that and I found out it is very easy to clone the external SD back to the internal without open the IT !!!

I found that everytime I run sfdisk, after creating the FAT partition, it just mounts by itself and all the failure bunanson described come after. Keep going, and the cloning process just fails.

He reported getting it cloned and booted, http://internettablettalk.com/forums...525#post130525, thread #18. I think the kernel is the key, I will try tonight. Would you? I have ordered another 8G card, see whether the first one is defective, I doubted it. And if still does not work, I will also ghost my working 4G onto my 8G card, I need the space for nwiki, http://internettablettalk.com/forums...581#post130581, my next project.
