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.
