Notes
Regarding data concerning tests with RAM expansion, all memory slots are installed with the maximum capacity of supported RAM.
During testing, the maximum number of SSDs supported by this model is installed in a RAID 5 configuration.
The testing standard was based on the maximum number of concurrent connections supported by this model. During the testing, 25% of the connections were used to transfer files concurrently. The transfer process guaranteed that the connections were not interrupted, the minimum transfer speed was not guaranteed.

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.
The maximum channel number also includes devices installed on Virtual DSM.
Total FPS may be affected by other services running at the same time (e.g., archive tasks performed by Archive Vault).
