You are pulling my leg, right? In case you are serious: Obviously, for 10Gb/s local network speed - You would need the all the intended devices to have 10Gb/s NIC, including the switch in between them. > And then there is this - two of the devices are Synology NAS devices > with SATA3 drives in them. How fast can they respond? Example for Synology NAS: https://www.synology.com/en-us/products/perfo rmance#5_8bay 10Gb/s LAN R/W speed: 2GB/s Read / 1GB/s Write 1Gb/s LAN R/W speed: 90+MB/s Read / 75+M/s Write > > People with desktop computers where they can insert a new 10GB > ethernet > card to connect to local devices that are also 10GB capable might see > a > significant benefit, but if the 10GB computer is the only device that > is 10GB capable, you're still going to hit a bottleneck at the other > end > of the connection. A chain is only as strong as its weakest link.
