The 'md' driver will let you set up an 'raid0' array using these two
drives.  This will result in a 180GB array.

The first 120 Gb will be striped over the two drives.  The remaining
60Gb will simply be the end of the larger drive.

You can, ofcourse, also set up a linear array.

man md

(with mdadm installed).
