Thanks for doing this. I see the huge differences, but there is nothing in log1 that says the MinimServer process is doing the disk I/O. It is noticeable that log2 contains very similar entries to log1 but in smaller quantities. This would correspond to the smaller amount of network activity that is happening when MinimServer isn't running.

If the NAS is connected to the network and MinimServer is running, there will be lots of "UPnP chatter" across the network. I believe the additional disk I/O that is being logged in log1 is a side-effect of the increased network activity that is caused by this "UPnP chatter".

The best way to eliminate the "UPnP chatter" is to run the disk I/O logging test with the NAS disconnected from the network. This will provide definite confirmation whether MinimServer is doing something that is causing disk I/O to occur.
