RAIF > has three main advantages over traditional driver-level RAID systems: this sounds very interesting. did you see the paper on chunkfs? http://www.usenix.org/events/hotdep06/tech/prelim_papers/henson/henson_html/ this sounds as if it may be something that you would be able to make a functional equivalent to chunkfs with your raid0 mode.
