UnverifiedNAS或多设备内网传输场景应选全千兆交换机，百兆交换机单口理论上限仅12.5MB/s，会成为万兆网卡和SSD的传输瓶颈87% similarUnverified接入NAS或做局域网内网传输时优先选2.5G交换机而非千兆，机械硬盘阵列/SSD的读写速度已远超千兆(约113MB/s)上限，千兆会成为瓶颈84% similarUnverifiedNAS + 万兆需求场景：主机与NAS互传选万兆网卡+2.5G/万兆混合口交换机，实测大文件传输可达900MB/s以上，仅升级千兆无法突破125MB/s上限84% similarUnverified构建高速内网(NAS+多台PC)的标准路径：核心用2.5G/万兆多口交换机做骨干，各房间墙面网口回接，NAS和主力PC接高速口，其余设备走千兆下联，兼顾成本与性能80% similarUnverified千兆网口扩展坞在USB-C带宽紧张时实际速率可能不足，对NAS/大文件传输有需求的选带2.5G网口的扩展坞79% similar
