Intel Matrix question

[Aurhinius]

Thinking of getting 3 x 320 gig drives, 7200.10's or AAKS's either or..

I want to use the bulk of the drives i.e 200 gig of each drive in raid 0 ( so raid 0 across 3 drives)

The other 120 gig I want to mirror.

What I don't want to do is end up wasting the space on one drive so is it possible with intel matrix to set up 2 drives 120 gig parts as RAID 1 with the other drives 120gig part as a hot spare?

I know matrix can almost do it I was more interested if it would accept raid1+hot spare across the 3 drives or just force me to use 2 drives for raid1.
