RAID-1 makes the data more available when a disk fails. That is, in almost all cases your data remains fully accessible when you replace the disk. For many people that is an important aspect.

If you decide RAID-1 isn't needed, then I'd suggest jbod (two volumes). RAID-0 is fragile - when either disk fails you lose everything in the volume.
