You make it sound like if it was introducing a write every 5 seconds, no matter what (and then conclude it'll wear flash).

It is not. If there are no writes there's no log to write. In fact, it'll try to combine writes done between the 5 second period, which may actually help reduce wear.

My worry is the unneeded performance hit.
