Just upgraded my TrueNAS server to 2.5g and my Win10 PC and am also having some issues with max bandwidth. I used iperf which should be able to saturate the ethernet connection independent of SSD speeds etc. But I also can only get a max of 1.61 Gb/s so far. I am suspecting maybe its the Realtek drivers or how they are implemented. So I have got an Intel 225 based NIC on the way to try that and see if there is any difference. The switch shows both ports are operating at 2.5G. Glad I found your example tests here.
Thanks for your comments Jerry, and there are some 2.5 GbE adapters in the market today which only go up to 1gbps... Link says they are operating at 2.5 but speeds tell otherwise. Enjoy your faster networking.
@@TechnologyMoments Managed to sort out the issue in my case. It was the number of PCI lanes actually available and not the adapter itself. Moved it to another slot with known X4 lanes and poof 2.48gb in both directions. Oh and that was on Realtek or Intel. Keep up the good info.
Hmmm strange. I've got two desktops with 2.5gbit nics and a switch and I can transfer between them for a sustained 280MB/sec. not sure what's wrong with your setup.
Hi, wherever you have a USB 3.0 you can use these 2.5 GbE adpaters. They work great. Remember you also need to have the switch you connect to, compatible with 2.5 GbE as some jump from 1 to 5. Something like this amzn.to/3Z5Juk5
That´s right plugable are great, we recently have been testing otther 2.5 GbE adapters and cannot reach more than 1.4 gbps, that is why we have not released more recommendations.
@@estusflask982 you can clearly see the ssd bottlenecks it at 6:33, it’s at 100% use. It obv can’t write quick enough, that’s why when he reversed the test it can go faster when reading instead.
@@estusflask982 Minor corrections: 2.5gibt is a little less, closer high 290MB/s max due to overhead. This USB device obviously has significant additional overhead as it is only hitting 260MB. And all (or rather any non-crap) SSD is going to be 550MB/s all day as they all max out the limits of SATA 6.0 connections.
