People went back and forth on the list saying that if a hardware controller was out of the budget right now RAID 10 would be the best solution.
That is raid1+0. raid10, under md, is something else different from raid1+0.
It seems that the installer wont let you create two RAID1 with the same mount-pount and it looks like you have to specify one. I dont see how to do this and I dont know how to make a custom installer for this.
You should mark those two mirrors as raid and then use them as members of a stripe array. If you cannot do that, then you will just have to manually do it on a shell (Alt+F2) and get the installer to rescan the raid devices.
