Answering my own Question, maybe it's useful for someone else: i was able to reduce the writes without changing anything, just setting up everything from scratch solved the problem. I think routeros has some bugs causing strange effects if you reconfigure it without complete resetting the configuration. (e.g. i could't delete proxy store, etc)
Since i didn't want to interrupt the production machines, I did it all on routers in our office, and later rolled out the corrected settings in form of a backup. The procedure is like this: - make a backup of the affected router - restore it on a local one in our office (which was updated to the newest version of RouterOS, e.g. 5.15 instead of 4.x), - create a compact export, save it for later use - reset configuration (no backup, no default...) - set main (intra) interface address and passwords thru winbox - ssh to the box and reconfig by carefully pasting parts of the exported configuration. there were some things i left out like a now obsolete address or route, but no really significant changes. Sector writes dropped to zero.
