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
