The big (and perhaps only) advantage to bound sets is that you can add
a device to an existing volume or set whenever you need to.  No copy-
and-wait step.  Almost full?  Just add another.

I have no experience with host-based RAID except for shadowing.  If
you know how big a set you want before you set it up, RAID 5 should
theoretically give you both performance and redundancy.
