May 16, 20251 yr Hi everyone. Recently I purchased a TP-Link UE302C USB Type-C to 2.5 Adapter to upgrade my Unraid box, which is still stuck with 1Gb NIC. My network setup is as followed: Client: Windows 11 PC, Intel I225-V 2.5Gb Lan Switch: Ubiquiti Flex Mini 2.5Gb Router: ASUS RT-AX82U All connected via Cat6 cables, no more than 30 metres. The TP-Link adapter was recognised by Unraid after I installed the Realtek driver plugin I attempted a file transfer, just a 10GB file and that was the speed. It was much better than what I used to have around 70-90MB/s, but not near 2.5Gbps level. Is there anyway I can identify the bottleneck? Thank you in advance for your advice.
May 16, 20251 yr 188 Mega Bytes / sec is 1504 Mega bits / second (1.5 Gbits/sec) , about 60% of the maximum possible. My experience is that the disk(s) on the Windows client and the host can be a limiting factor in transfer speeds. The suggestion to try using iperf is a good one, it minimizes disk speed as a factor in the test. -- Tom
May 16, 20251 yr Author From Unraid to Windows: From Windows to Unraid: Looks pretty close to 2.5Gbps, so I guess the connection was not the issue. Thanks Tom3 for the suggestion, my Unraid server has Seagate Ironwolf SATA HDD 7200rpm, the Windows 11 PC has all Crucial P3 SSDs, do you reckon this might be due to the reading speed of the HDDs?

May 16, 20251 yr Author Thank you for your help, at least now I know the network upgrade was a success, and I have more room for an all SSD Unraid box in the future, if I ever save up that much cash and/or SSDs become cheap.
