Hello,
AFAIK, RAID1 doesn't do any striping, so no matter how many disks you
include in your array, you have a maximum usable device size equal to
the smallest disk in the array. In your case, your maximum disk size
would be 640gigs.
It sounds like you want to do something like RAID5; you'd have some of
the benefits of striping and some of the benefits of mirroring. I've
only ever setup a RAID1 array with Debian, and I don't remember what
options were presented during installation. You might be able to
replicate RAID5 using LVM + RAID1 if RAID5 is not an explicit
installation option. I have yet to experiment with LVM, so I don't
know what this would entail, but I'm sure other members of this list
could be more helpful in this area.
Regards,
Elijah
