Sorry again, I'm confusing everyone. I have 2 servers, one with 6 drives and another with only 4 drives. I get the same results with both.
The above numbers posted were on the box with only 4 onboard sata drives. I've even tried different filesystems, XFS and ext3, still same thing. So I'm guessing something weird with mdadm? These are 64bit etch systems.Perhaps I will make a bigger array and split it into more partitions and see what happens.
