Another RAID ? for Nick

Currently have FSX on a RAID0 array with 2 74G Raptors using NVidia built in manager. Thinking of several things:
1) break the array into 2 74G individuals or
2) buy a 150G Raptor
If I decide to do either of these - can I just Ghost the RAID data and then copy it back to the 150 or 74 or is there a better way? (Reinstalling is NOT an option)
Last - system is running just fine now, will any performance difference be worth the effort or am I just looking at a "purist" solution. At my advanced age I can no longer tell the difference between 10ms and 20ms. :)
