E10G22-T1-Mini will only run at 5 GBe

[Enquiries]

Installed E10G22-T1-Mini into a DS1522+ with 2 8TB Iron Wolf drives, but I am only getting 5000 Mbps (LibreSpeed averages 4800 Mbps). I have connected a USG-Flex-XG (connected to 1522+, desktop, and UDM-Pro (SFP+ to Copper set to 10 Gbps)). My desktop is running at 10 Gbps but the NAS will only run at 5 Gpbs - if I select 10 Gbps the NAS will disconnect from the LAN. SFP+ transceiver is a 10 GBase-T SFP+ to RJ-45 10 Gbe.

Any help/suggestion to get to the 10 Gbps will be greatly appreciated.

Each HDD can achieve speeds of around 150-200MB/s. I would not expect anything faster. NVMe pools would allow these speeds though.

I hope this helps.
