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.
