I am currently building a RAID setup for storage of iTunes and other files. I have 4 hard drive spots to work with. I have been throwing around a few options. Any suggestions on the safest way of doing this would be great! Option 1: 4 x 1.5TB (2x1.5TB RAID 0 + 2x1.5TB RAID 0 Clone) What would be the worst case scenario with this? if one hard drive fails I would just use the clone or vice versa. Option 2: 4 x 1.5TB RAID 1 with no clone. Which of these is the better option? or is there an option 3?
