Hi John,

I haven't done much with any of these solutions yet, but I think each
one can do what you want, with various pros/cons:

Vinum: http://www.freebsd.org/doc/en/books/handbook/vinum-vinum.html

RAID0 striping:

ZFS: http://www.freebsd.org/doc/en/books/handbook/filesystems-zfs.html


Hope that helps get you started,
Greg
