> ... or fossil/venti servers with RAID disks.

i had this conversation with a mate of mine the other week.

RAID controllers are expensive, overly complex and prone
to failure.  i didn't agree 'cos i'd seen one that didn't fail.

however i was compelled by his logic that the controller
i was using [Digital Storageworks] expensive and
probably over complex.

we agreed that mirroring is simpler, less error prone and
now that disks are cheap going to RAID5 is a complete
waste when it can be trivially replaced with mirroring.
