It looks the replacement went without problems and the speed of the virtual disk rebuild was impressive running at 6Gbps. We will probably go your way and replace at least in this server all disks with 6Gbps ones and probably witth the 6TB ones as well. Is it normal that the disk status is Non-Critical? Is it because of the disk being not Dell certified?
