RAID0 on database server?

I don't think it is that bad an idea to have RAID0 on all servers if
you are a startup and have limited resources. As long as you are not
really mission critical and there are backups, you will enjoy superb
performance even with low RPM drives like 7200RPM.

After seeing the mind blowing performance, I am sold out on RAID
forever. Even for my desktops!
