Depends what RAID You Do For example, If yopu wanted to RAID 1 the two drives your total storage space would only be 40 GB since that is the smallest Drive.
If you were to RAID 0 the two drives your total Space would be only 80 GB, again your smallest Drive is the 40 GB one, so 40 X 2 is 80.
Now you shouldn't RAID those two Drives because they aren't Identical and differ in Speed.
You Could Do JBOD (Just a Bunch of Drives), in which your total Space would be 120 GBs ( 80 + 40) XP would see both drives as One 120 GB one.
