    I was rather hoping to be able to boot from a RAID5 array, giving me a
    safety net in case of disk failure but still giving me effectively 3
    disks worth of storage space. Using two RAID1 arrays would be an
    alternative, but that would mean having less space available.

    I am uncertain of the perfomance penalties of the ZCR/RAIDIOS setup,
    though the press releases (but the vendors, naturally) imply that it
    isn't too serious. As for saturating the PCI bus, I have no immediate
    use for it, nor do I envisage needing it at any time in the near
    future.
