Edit to my above post . . . .

Since your drives are not all the same size RAID 5 would not be efficient. Your two best options are, IMO, RAID 10 or RAID 01.

RAID 01 is a mirror of stripes. In your case you would stripe (RAID 0) a 1TB drive with a 500GB drive (and then do the same with the other pair). Then you would mirror those two stripes (RAID 1).

RAID 10 is a stripe of mirrors. To do this you would mirror your identical drives to one another (RAID 1) and then stripe those mirrors (RAID 0). Generally speaking, I would recommend RAID 10 over RAID 01.
