With 4x2TB drives, I requested RAID 1 from setup. I expected 2 mirror sets of 2x2TB drives each, resulting in 2 separate drive letters, and a total of approx 4TB storage. Instead I get one drive letter, and one partition of approx 4TB.
Would somebody explain this to me. My concern is that I don't have the max possible protection enabled for the data. I don't want this to be a RAID 10 or RAID 01. In those configs, if you lose the "wrong" 2 drives concurrently, you lose "all" your data. But with 2x2TB RAID 1, losing the "wrong" 2 drives will lose you at Most "half" your data. What's really happening here?
