I don't see RAID disappearing from the computing landscape anytime soon. 
The architecture and performance of some RAID controllers are starting 
to rival the systems they are connected to. There is a case to be made 
for simplifying things and bringing the storage and filesystem together 
and ditching the RAID controller. Distributed i/o and better latency 
would be a great thing for demanding apps and talented administrators.

One service RAID controllers provide is fencing a complex low level 
command/control environment from direct user interaction. Some people 
are better served by having their data sequestered behind a RAID controller.
