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.
