Excuse what might be a foolishly simple question.
My intention is to drop two equivalent HDD into my DNS-323 and run a RAID 1 setup.  I understand that if I drop two 1 TB drives in, I effectively get only 1 TB available storage (because of the mirroring).
But when I go to configure my DNS-323 I get the impression that the storage "maps" to a single drive letter.  In other words, my available storage capacity of 1 TB would be mapped as a single volume.  I cannot "partition" my drive as I would an internal HDD into various volumes.  Is this correct?
