Notes
"Compatible drive type" indicates 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.
Each internal volume (may consist of multiple drives) is expandable up to 108TB.

Notes
Surveillance Station throughput is tested with Axis network camera, using continuous recording with live view from Surveillance Station and motion detection by camera. Live view and recording are sharing the same stream from the camera.
Total FPS may be affected by other services running at the same time (e.g., archive tasks performed by Archive Vault).
The maximum channel number also includes devices installed on Virtual DSM.
