You don't want a problem with a single drive to take away everything you have, like RAID0 does. The only good case for RAID0 is temp/buffer files that you don't cry if you lose.
Anyway non-RAIDed simple setup is also vulnerable to drive failure. So backup (and RAID1 if you need HA) is the solution, not non-RAID. RAID1 just make x2 failure rate.
