> The raid will use 3 or 4 identical harddrives. Is that mirrored? If so, heres a gotcha:
http://www.openbsd.org/cgi-bin/man.cgi?query=raidctl&sektion=8 "Note as well that RAID 1 sets are currently limited to only 2 components. At present, n-way mirroring is not possible." However, I think with multiple layered mirroring, what you want is possible. As stuart has pointed out, upgrading that will not be as easy as it could with hw raid. Hope that sves you some time and frustration. regards Edd
