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). |
Synology Drive | Recommended Number of Hosted Files | 1,000,000 (applies to files indexed or hosted by Synology Drive. For file access through other standard protocols, refer to the File Services section above) |
Recommended Number of Concurrent Sync Clients | 550 (the number of connections that can be maintained when the recommended number of hosted files was reached) |
Notes | Exceeding the recommended numbers above will not block application operations, but may result in longer response time. Utilizing SSD cache can significantly improve performance. For tested models with expandable memory, the maximum amount of RAM was installed. Btrfs file system and non-encrypted shared folders were used during the aforementioned testing. |
Synology Office | Maximum Users | 1,800 |
Notes | Multiple files were opened for testing and each file was edited by 30 users simultaneously. For tested models with expandable memory, the maximum amount of RAM was installed. Client performance may affect maximum simultaneous editing users. Client PCs used for testing: Intel Core i3-3220 / 8GB RAM |
