            | Notes | 
                "Compatible drive
                  type" indicates the drives that have been tested to be
                  compatible with Synology products. This term does not indicate
                  the maximum connection speed of each drive bay.The maximum raw capacity is not
                  limited by the maximum single volume size. Synology NAS models
                  may utilize capacities over the maximum single volume size as
                  long as each volume created is below the limit. (Learn
                  more)Expansion of the internal volume
                  is only supported if the combined single volume size does not
                  exceed the maximum limit of 108TB or 200TB if upgraded to 32GB
                  RAM or more. |
