I'm trying to decide on a flash device and filesystem combination for an
embedded device. My concerns are:

- Wear leveling
Does jffs2 wear level across partitions, or just within a partition?
Is the M-Systems hardware leveling controller worth a damn?
Is it preferable to using jffs2?

- log data
How to structure disk layout best to be able to get log data while not
significantly shortening the flash life.

- cost
What's the cheapest device I can get away with.

I need 1-2 GB, almost everything is static, except for log data. I plan
on having a log on/off switch, but I want to be able to log anomalous
events by default.

Thanks, Bruce
