One drive to raid - reinstall OS?

[Ol!ver]

I currently have one drive with two partitions, one OS on each. If I get another drive, or two new ones and want to raid them for performance, will I need to reinstall the OS?

Is there much benefit to raid? I often move large files around.

Cheers

Reckon I'll do away with the RAID idea as I can't be doing with reinstalling two OS' that I've just got working as I want.

How easy would it be to install a new 500gb drive and clone the two partitions to it, meaning that I can then take the old one out and carry on ?

That's easy. Either Ghost (2003 for preference) or Acronis True Image will do it and you can download a trial version of ATI.

Using OS X. I'll use CCC.
