    ¹ Synology reserves the right to replace memory modules with the same or higher frequency based on supplier's product life cycle status. Rest assured that the compatibility and stability have been strictly verified with the same benchmark to ensure identical performance.

    ² "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.

    ³ Storage Pool and volume creation require all drives to be listed as compatible on the device model's compatibility list.

    ⁴ Noise Level Testing Environment: Fully loaded with Seagate 2TB ST2000VN000 hard drive(s) in the idle state. Two G.R.A.S. Type 40AE microphones, each set up 1 meter away from the Synology NAS at the front and rear. Background noise: 16.49-17.51 dB(A); Temperature: 24.25-25.75˚C; Humidity: 58.2-61.8%.

    ⁵ Power consumption is measured when it is fully loaded with Western Digital 1TB WD10EFRX hard drive(s).

    Notes:

    • Model specifications are subject to change without prior notice.
    • The figures are based on Synology internal testing. Each performance test is done individually. No other services or applications are processed at the same time.
    • The actual performance may be lower than lab testing figure due to differences in server configuration, deployment, and the number of active operations.
    • If usage requirements exceed the specifications above, please contact our regional partners for professional advice.

  • 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.
  • 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.
  • EXT4 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.
  • Client performance may affect maximum simultaneous editing users. Client PCs used for testing: Intel Core i3-3220 / 8GB RAM
  • The host that implements Synology High Availability does not support Virtual Machine Manager.
  • This specification varies depending on the system configuration and the amount of memory.
