Yes. It's still a valid proposition that raw disk is fastest if you map cleanly to the block abstraction the integrated controller offers, if only because of avoidance of indirect call stacks to carry data into the device.
But that said: the DBA in question constructed a catenated drive, not a stripe, and were slightly dismayed when we found out it was working at the speed of one disk interface and using only the front pack, not all of them in some kind of parallel or interleaved manner. Not a very smart DBA it turned out.
