Actually, with the 3ware cards, the disks can be plugged into most any 
newer controller and "just work". From what I've seen in the manuals for 
3ware controllers, the disk "format" is understood by pretty much all 
newer controllers. For example, a disk set from a 9500 series card could 
be placed on a 9550 or 9650 and the card would know what to do with them.

If this continues to be the case, replacing a failed raid controller is 
much less of an issue.
