Say I have a RAID 1 config of two 1TB drives. (1TB of storage)
I take one out, insert a 2TD drive and let it rebuild. (Still 1TB of storage)
Now I take the second one out, and insert a 2TB drive and let it rebuild.
Do I end up with 2 TB of available storage, or just 1TB, from the original configuration?
Does the answer change for RAID 5 or 6?
