• 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.

• The number of concurrent HTTP connections for Synology Chat was configured to the maximum.
• For tested models with expandable memory, the maximum amount of RAM was installed.

• The maximum number of concurrently connected devices refers to the maximum number of devices that can remain connected at the same time.
• The maximum number of hosted files refers to the maximum number of files that can be indexed and hosted by the Cloud Station Server service. RAM expansion was not used during testing.
• Non-encrypted shared folders were used during the aforementioned testing.

• Models with more than 4 bays were installed with two SSDs for SSD cache.
• For tested models with expandable memory, the maximum amount of RAM was installed.
• The performance of the mail system will slightly decrease in high-availability mode due to data synchronization between the two servers.
• Functions that were enabled in all of the tests above: anti-spam, anti-virus, DNSBL, greylist, content scan, full-text search (English only).

• 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).

• 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.

• 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
