Cheers Michael - that's a great bit of info. Do you know how to do RAID5 ?
I read in

http://www.essenz.com/support/lists/hackers/20040118/69.html

about geom_raid, but it seems to be lost after that.

The other alternative may be to setup a RAID1+0, but that shrinks my 
usable space, and I'm not sure how reliable/advisable it is to do in 
software.

Thanks again,
Beto
