It would be really nice because one of the short comings of RAID 5 is the window of vulnerability during the rebuild time. I have heard it can take as long as a week rebuild a large RAID 5 with heavy ongoing disk access. (That might just be EMC propaganda, I have never seen it take that long). EMC has what they call Parity Raid. I don't understand it, but they claim it is faster and more robust than RAID 5.
