I see this statement all the time. You have to reinstall Windows to implement RAID 0. It's simply not true. All you have to do is install the Intel Matrix Storage Manager, activate the Isastorv service instead of the Isastor service, build your RAID array, and clone your current hard disk drive to the RAID array. Thats it. Id did it again today with Server 2004R2 so it will also work for Windows 7.
