Portability is no different with a RAID controller as long as you've
standardized on controllers. Our situation is not standard but
hundreds of drives are swapped between machines throughout the month without
an issue. We use RAID sets to transfer large amounts
of data (TBs) between machines. All systems use 3ware 9550 or 9650
controllers though so you throw the set in and rescan an it's there.
