Raid 1 = Two HD's or more with the SAME files on each drive.
Benefits = 1 HD fails, doesn't matter, you have mirror copy on your other drive, redundancy is your friend. 
Drawbacks = Loss of capacity - i.e. you have 2 1T HD's, but now only 1T of storage as they are BOTH the same HD.
With HD's cheap as can be these days, Raid 1 is the way to go - the speed of Raid 0 but without the risk. |
And I believe RAID 5 offers striping to improve performance, along with the redundancy offered with RAID 1. I'm not sure but I think you have to have 3 identical drives to run that setup.
