I want to separate my indexes into a tablespace which resides on a raid0 
disk for fast r/w access. Is it safe? what I mean is, if the raid0 disk 
is damaged, is it easy to recover the indexes by just recreating those 
indexes?

You should be fine doing this from a technical perspective.  Make sure you think about the impact of temporarily not having the indexes in place.  Can you keep your system down while you rebuild the indexes?  Can you limp by while you are rebuilding the indexes?  

Brad.
