— fast wired Ethernet port (usually 2.5GbE, less often 5GbE/10GbE) provides noticeably more bandwidth than the standard 1GbE. In actual file transfer, it feels like this: if a gigabit usually hits around 100–110 MB/s, then 2.5GbE can offer about 250–300 MB/s with the right network, so large copies and backups to NAS, video editing from a network drive, or transferring projects between PCs take significantly less time. Unlike Wi-Fi, wired LAN is more stable in terms of latency and less affected by interference, and compared to the usual 1GbE, the main advantage is speed "like a fast external SSD," but it’s important to remember that a compatible router/switch and the right cable are needed, otherwise the port will work as 1 Gbit/s. For example, if you play competitive shooters/online matches while downloading stream recordings, updates, or keeping Discord/OBS running, a fast LAN helps so that background load doesn't "shake" the connection as much, and in a home network, you can quickly transfer large games to a second PC or NAS without waiting.
