RAID 10 requires 4 drives. It's great for very data intensive, I/O driven applications. For example, when I worked with Oracle previously, their mantra was "RAID 10 everywhere".
I can't tell you if your MB supports 0+1 - why do you think you want that over 1+0? There's no speed advantage that I know of, and 10 gives you greater redundancy.
As far as which drive, it's really a cost/benefit question. Good SSD > Raptor > plain old SATA. Is what you're doing worth the expense to you? For me, once you've spent the cash on 4 HDs in RAID 10, it's already going to be so fast that something like Raptors or SSDs is overkill for a home/gaming PC.
