Im so glad you are up and running. You wont regret having a fast raid. It will enhance your capabilities from this time forward.
At one point in our trouble shooting I thought that the excessive file size might be an issue, but I discounted that notion since I never have heard of that being an issue.
Again, congrats for hanging in there and solving a very challenging issue. Your system now will handle just about anything you can throw at it. 😀
