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89% 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87% similarUnverifiedNAS或PC配备2.5G/万兆网卡时，交换机必须选2.5G及以上端口才能突破千兆瓶颈；单纯换千兆交换机对2.5G设备无提速意义84% similarUnverified有NAS/内网文件服务器或需内部大文件传输的场景，LAN口和主干应上2.5G或万兆，只有千兆口会成为内网瓶颈；纯上网办公千兆口足够，无需为2.5G溢价83% similarUnverified千兆网口的NAS即使加密性能再强，实际传输上限约110MB/s；若追求加密后仍高速传输，需选带2.5G或万兆网口且CPU加解密吞吐足够的机型，否则网口成为瓶颈81% similar
