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 above recommended specifications, please contact us.
