RAID question

I want to set up a RAID 1 array to add a little extra data security. I've
already purchased another hard disk that's the exact make/model of the one
already in my system (a 160-GB Western Digital WD1600JD).

My motherboard (an Asus A8V Deluxe) has both the VIA K8T800Pro chipset
supporting two Serial ATA connectors with RAID 0, RAID 1, and JBOD
functions, *and* a Promise FastTrack 20378 controller providing another two
Serial ATA connectors for RAID 0, RAID 1, RAID 0+1, and multiple RAID
functions.

Which one should I use? Are they both considered "hardware RAID" solutions
and, if so, is there much of a performance difference between the two?
Obviously, I'm not a RAID expert, and this is my first foray into the world
of RAID, so I'd appreciate any helpful advice from the more experience
RAIDers in this group.

FYI, here's the link for my mobo info:

I see now that I worded my question stupidly. I meant, which RAID solution
should I use? The chipset-provided one or the Promise one?
