Thanks for sharing Grant. Your point about hardware raid is well taken.
However, the discussion is about Fake-Raid vs. Software RAID1 and
controller/chipset dependence and portability. The portability of a
software RAID1 hard drive to an entirely different box is, I have
learned, much higher and less time consuming.

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.
