You can find a hardware RAID 1 and 0 card for under $400 Canadian. I've
even found one for under $300 that is not only good I was surprised to find
it was cutting edge. Check out sonnam.com they have some 3ware RAID
controllers that you might use but they also have the 3ware RAID card I just
mentioned. I think it's the 7000-2.
