slice one drive for root, swap and the rest ZFS. Install on that drive and create a raidz pool with the other drives, benchmark. Slice the other drives in the same way as the first and build either a raidz pool or a stripe of two of mirrors from the four ZFS slices, benchmark. The time will be well spent.
