I'm not sure that would provide much more reliability, however. If
you're adding a second device to use the journal you risk losing data
if either device fails... given how small the data is (I believe 32
bytes per entry), I'm not sure it's really worthwhile. Most of what
I've read in the past about FreeBSD's FS interactions seems to imply
that the lower-level (ATA-layer) is not terribly optimized for larger
drives and faster interfaces available these days. I'm sure I could go
Google up some references, but I think it's been well covered in the
past.

Cheers,
