That's working normally with the sync completed. Mirrors should run at close to the speed of a single drive. Maybe you are just expecting too much from SATA or you have something like an updatedb running. An 'hdparm -tT' against the partitions and md devices should give you an idea of what the drives can do. And top might show what's causing the load (but maybe not if it is mostly waiting on disk seeks).
There should currently be virtually NO disk I/O on this box right now. Its a bare install and I have not installed any apps yet. Is there an easy way to tell whats using all the I/O? The drive activity light never goes off. I did a torch in my firewall router and there is no network activity going to it.
