I think this is certainly the wrong direction. Manufacturers can't even get hard disk firmwares let alone RAID right much of the time. Expecting them to to do even more complex tasks is asking for trouble.. not to mention obsolescence: they likely wont release updates after 2 or so years if they are feeling generous.
The future of mainstream storage is squarely in solid state technology such as flash memory, holographic storage, memresitors, etc. It only makes sense to treat these as low as possible: arrays of raw memory addresses just like RAM.
With many core processors, it seems foolish to even think about this these days.
