Where RAID-0 is particularly useful is when used with conventional hard drives, since they are relatively slow compared to an SSD.  RAID-0 will give you approximately twice the sustained transfer rate of a single HD, since the controller is continually "toggling" back and forth between the two drives.  It can also slightly improve the latency as well.  Since SSD's are so fast (approaching the burst rate of the controller), doubling the speed of the SSD's (RAID-0) doesn't get you much performance improvement because the communication interface is saturated.
