You're looking for the ammounts of writes for the disk block that gets
the most writes.

E.g: for a standard ext3 filesystem, the journal area would probably
have very frequent writes, whereas most of the system would remain
mostly unchanged.


Again, if the embedded system is setup properly, there is NO writing to the flash during normal operations, thus the device won't be killed by its alleged 2 million write limitation.

Kris and I had a quick discussion on this topic, off-list, and his original flash-based device is still in constant operation after 2 years and I have flash modules that I purposely tried to kill with writes. It took significant effort to start causing error situations, which were very easily detected before the system would become unusable.

Erick, you should focus on having a quick action restoration plan and extra DOMs always readily available. Then when a failure situation is detected, you can react very quickly.
