There is ccd - "Concatenated Disk drive"; see "man ccd" for details.
Also see the chapters in the Handbook:
The Vinum Volume Manager
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/vinum-vinum.html
RAID
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/raid.html
Those might be informative and inspiring.

One thing is to use gstripe and gmirror, other is ZFS (but your
machine should be _good_ to actually make use of it).
