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.
