It looks like the Class 4 is being utilized with N800. Luckily I did not go and get the cheapest Class 2 card.
lol like Milhouse did.

Those read speeds are pretty similar to my Class 2 to be honest (I'd wager identical once you eliminate the variance introduced by the stopwatch timing) and the write speed I observed (6.4Mb/s) is significantly better than the Class 4 card.
All in all, I'm very happy with a cheap Class 2 device in my N800 thanks euchprof - but feel free to blow your cash on a Class 4 if you think it justified!
I certainly don't think it is - the only benefit of Class 4 over Class 2 is when using the card in a PC card reader and performing bulk transfers where you should see improved write performance.

In that case at $5 difference, fair enough - you can't argue with that!

While at it... anybody has any suggestions about PC card reader? Are all/any SDHC compatible USB card readers able to utilize Class 4 or even 6 speeds? How about bigger cards than 8GB?
In Ebay I see some but suspiciously they seem to limit up to 8GB size and talk about supporting 150X max speed and/or Class 2...
Maybe I need to search some Brand Name products and see if they publish specifications where these are defined properly...

a standard SD card reader doesnt seem to read SDHC. i got sucked into buying a 4GB SDHC card at CompUSA when i got my n800, from SanDisk and it came with a usb-2-sdhc reader. it ran $129 for the card, but the reader makes up for the ghastly price.
you can connect the n800 to a pc via usb, and read any card that is mounted in the n800.

Fortunately, my cards also came with little USB readers; they're now essentially USB flashdrives with the low-capacity cards I've been accumulating over the years (well -- months...).

Need help, maybe i do something wrong.
I want to use with n800 Kingston 4Gb SDHC.
I'm trying to patch my n800 with sdhc kernel patch from device itself, but after string "./kernel_flasher/kernel_flash sdhc.bin" it asks "Are you ready to flash? (yes/no)" and then message appears:
"Nothing flashed.
Cleaning up... done."
After reboot n800 can't find card.
Sorry for terrible English.
