I'm looking into building a six-disk raid10. The six disks are comprised of three from one manufacturer, and three from another. My intuition says that for better statistical reliability, the redundant data copies ought to fall on disks of different manufacturers. I know I could achieve this easily by building a "classic" RAID1+0 system: three RAID-1 sets built by manufacturerA+manufacturerB pairs, then striping those mirrored sets in RAID-0. But based on what I've been reading, looks like mdadm's more sophisticated raid10 layout schemes give better performance. For example, can I create a raid10,f2 set in such a way as to meet my "redundant copies on different manufacturer" criteria?
