a kick in the ass does a body good...
Now, I just have to make sure I dump the databases off to the new disk properly and everything can find it. We should see reduced IO wait times when things get hot and heavy. someone correct me if I'm wrong. We aren't running a RAID, just adding another disk that can look for data while the other disk is doing it's thing.
I bet I could run the databases on a RAM disk and just rsync them (every 5 minutes ?) to the disk to really speed things up, but any emergency server restart would lose a little bit. That doesn't happen too often if ever.
