Internal and External Network Transmission Speeds
1. The transmission speed between the NAS and each terminal follows the principle of "the transmission speed is determined by the lowest speed of the two connected devices."
If any link in the local area network (LAN), such as the router, switch, network cable, computer network card, or NAS network card, only supports a speed of 100 Mbps, the maximum theoretical transmission speed can only reach 12.5 MB/s (100 Mbps ÷ 8 = 12.5 MB/s), rather than the common 100 MB/s under gigabit network conditions.
Therefore, it is essential to ensure that all network link devices support gigabit or higher speeds. Upgrade the router, switch, network cable, computer network card, NAS network card, and other links to the same network conditions, such as an all-gigabit network, all-2.5G network, or all-10G network, to ensure that the maximum transmission bandwidth of the LAN can reach 1000 Mbps (theoretically 125 MB/s) or higher.
2. Prioritize wired connections for more stable transmission.
It is recommended to use a wired network for data transmission whenever possible, as this can effectively avoid speed fluctuations commonly encountered in WiFi environments.
Especially when transferring large files, wired connections can significantly improve transmission speed and stability. If only wireless transmission is possible, it is recommended to connect to the 5GHz WiFi signal and keep the distance between the terminal and the router within 5 meters to reduce the impact of signal attenuation.
3. Optimize file transfer strategies to improve transmission efficiency.
Avoid transferring a large number of scattered small files at once, as such files can increase the time required for queued copying.
Pack and compress multiple small files into a single large file (e.g., in ZIP format) before transmission. This reduces redundant operations during the transfer process and speeds up the overall transmission.
About the Topology Diagram of Internal and External Network Transmission Speeds:
(1) Transmission speed between devices with the same network port in an internal network environment.
(2) Transmission speed between devices with different network ports in an internal network environment.
(3) Transmission speed limitations of hybrid network ports in internal and external network environments.
Special Note: The theoretical peak speed of common household gigabit wireless routers in the 5GHz band is approximately 2400 Mbps ≈ 300 MB/s. However, the actual transmission speed is limited by multiple factors:
a. Affected by the signal strength of the router.
b. Affected by the distance between the device and the signal source.
c. Affected by obstacles such as walls that block or weaken the signal.
Considering these factors, the typical actual indoor speed can only reach 20-70 MB/s.
