Sorry for not getting back fast enough - very busy times .

Just let it run after the switch over - let the bond wait so we can trouble shoot one at a time.

Concerning the performance is was ready to jump on the disk drives but now in the end of your message that squelched that idea, unless firmware and or using 32bit mode made the difference of the drivers on the system - but don't think that is the case. We would have to see the logs to see if there is anything we can find to point us in the right direction. I would think the RAID 10 would do very well.
