I haven't done this on FreeBSD or with USB drives (but have on Solaris 
with SCSI). Make sure all your USB drives always show up as the same 
device (in /dev) or you may wind up corrupting your system.

That is the way I've always done it but I don't see any reason not to 
do it the other way. Just remember how you did it should you need to 
recover.
