Raid 0 mirroring on a preinstalled Vista machine

Vista was already installed on the machine I bought which came with only
one 160 GB SATA drive. What if I later on want to add a second SATA
HD? Can I then make it do a RAID 0 with the existing HD? Does it have to
be exactly the same size? Same brand? Same model?

Raid 0 is not mirroring. RAID 1 is mirroring. It is not likely you could add
a disk and then create either array without also backing up and restoring
your data afterwards. Some higher end controllers can build a RAID 1 array
on the fly but most lower cost solutions can't.

Raid 0 is striping, not mirroring. Exactly what do you want to accomplish?

Redundancy so that every bit is saved to both drives so in case one
drive fails, the other is intact. How about self healing from the good
drive?
 
RAID 0 has nothing to do with redundancy, but with performance. Look at RAID
1, it might be what you want. A number of newer controllers support creating
a RAID1 array from a single non-RAID disk. Same size, brand and model is
recommended but not required. Check your the documentation for your RAID
controller.
