I'll agree with all of that up to RAID 0. Raid zero is /asking/ for 
trouble. If either disk fails, you're likely to lose the data off both. 
As a result a RAID 0 array will fail at the failure time of the 
shortest-lived disk, so it'll tend to fail much earlier /on average/ 
than an individual disk.

If you need RAID, use RAID 1 (mirroring) for nice safe data or RAID 5 
for a compromise that while it eats some CPU time and slows down writes, 
allows you to use 2/3 or more of your data storage and provides a 
measure of protection against disk failures.
