What configuration gives 120GB from 80 + 60?
Is it not multiples of the smallest drive? Like (n-1)x, n being number
of drives and x being the capacity of the smallest drive?
RAID 0 (striped) would give 140G but you'd lose all your data if a drive
failed.
RAID 1 (mirrored) would give 60G as you only get up to the size of the
smallest drive.
RAID 5 isn't possible with less than 3 drives.
I think that settles it then... SCSI it is :-) They may be old, but
still more advanced. On the plus side, it frees up some drives for use
in other machines :-)
Unless the perfomance gap due to difference in age is sufficiently large,
or ATA has advanced to include command queueing...
