My system that had a hard drive failure while I was overseas, was configured as RAID 0. I currently have a RAID 0/1 matrix (RAID 0 partition for OS, RAID 1 partition for data) The performance improvements of RAID 0 over RAID 1, are noticabe IMO when working on large Photoshop files. It's good for a PS or video editing workstation, but I wouldn't rely on RAID 0 for file storage.
