I have a RAID 1 setup with two 500GB drives. So they mirror each other. I know that if I take one of them out and put in a new 500GB drive it will set it up so that the new drive will mirror the old one.

My question is if I take out one of the 500GB drives and add say a 2TB drive, will it set up the 2TB drive to mirror the 500GB? I assume if it does, it will only allow me access to 500GB. However, if I then take out the one remaining 500GB after the data has been mirrored and stick in a 2TB, once that is rebuilt, will I then have a 2TB RAID setup with the same data as what was originally on the 2x 500GB setup?
