Subject Different disk writes per node

I'm seeing different write patterns through out the nodes of my ensemble.
There's one node that's writing around 100MB/min but others doing 6x higher
writes.

The ensemble seems healthy, all nodes serving (not Observer). The instance
is running only Zookeeper with Exhibitor. iotop confirms that the writes
are from the Zookeeper process.
I was expecting that all of them to write roughly the same quantity because
of how broadcast works.

What's actually happening? Should I be worried about this?
Thanks.
