I think you would get the same reliability and better performance with four RAID-1 mirror arrays and RAID-5 over that. You still have to lose four drives to lose data, but you get the size of three instead of two. If you really care about it, use two controllers, put four sets mirrored one drive on each controller, then RAID-5 over that. > > This is on a Debian system running the 2.6 kernel.
