Best Practice for RAID 0 and defrag

I just bought an XPS3 with a 2x160 RAID0 stripe.   What are the limitations (if any) and recommendations regarding running a defrag on the volume?  Given that the data is striped and segments exist on both drives, is there a need, and can you do damage? 
 
Thanks!

Should be no issue.   Logically it looks like one drive.   So the OS does not see it any different than normally.  I normally run defrag not that offen and usually do it with no other task running.   But I am running RAID 1.

Thanks for the reply, but I'm not sure that RAID0 would behave the same.   The difference is that RAID1 mirrors all writes across both drives, so the drive can be fragmented and the fragmentation will be mirrored.  Since RAID 0 stripes across both drives to start with, it's by definition fragmented and the controller keeps tabs on the logical drives and the files.  
 
Anyone have any experience with RAID 0 and fragmentation?
