Hi
Has anyone compared the Read/(write) performance of the fs for NAND flash devices (1GB)
I want to make a (good) choice.

I know Artem would want me to recommend UBIFS, but the figures that have been presented do seem to bear out the claim of its superiority in the most common scenarios. I can't find the particular set I was looking for, but this place looks like it might have enough data to satisfy:

-- I tried the Vista speech recognition by running the tutorial. I was amazed, it was awesome, recognised every word I said. Then I said the wrong word ... and it typed the right one. It was actually just detecting a sound and printing the expected word! -- pbhj on /.
at the ELCE 2008 the guys from free electrons made an interesting presentation about flash filesystems, including benchmarks. you can find it at the wiki of the ce linux forum:
for a huge rw filesystem i think ubifs would be the correct choice. according to the document ubifs is superior in almost all benchmarks (except in case of relatively small partitions). it is supported by the mainline kernel (as opposed to yaffs2) and mounts much faster than jffs2. another advantage is the support for wear levelling across file- system/partition borders, which allows you to include read-only partitions in the wear levelling (if they are created upon UBI)

Mostly reading only (only write in case of software updates ) My opinion is to write to external media (sd) when frequent writing is needed
