RAID-1 is setup when you need fault tolerance and is a mirror of the the other drive. Therefore it is like a data backup in the sense that if one drive fails you still have the second drive fully functional and ready to take over the job.
When I asked these questions I was at work and unable to check due to time but I just wanted to share this now that I've looked it up myself.
Thanks for the help guys.
Yes, you get redundancy but what if you get a virus that eats away at your files/embeds itself in everything? What if there is a powersurge that blows both your drives? Ok, extreme examples but having RAID is not a guarantee. I was going to have a RAID0+1 setup but decided against it to have a external backup.
Also I found RAID0 has given me a slight performance increase with a 16k strip size.
Eric RAID5 can be on 3 or more drives. 6 allows for RAID50. ^_^.
Good link for different types of RAID: RAID level 5
