Lưu ý:

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.
