Questions about this item

Should I pick the 2.5GBase-T version or a slower 1G model for my 2.5G switch?

The 2.5GBase-T adapter matches your 2.5G switch at 2500Mbps, while a 1G model would cap the link at 1000Mbps.

What real-world throughput does the 2500Mbps rating deliver inside my PC?

The RTL8125B controller runs at 2500Mbps over PCIe x1, so sustained file transfers approach 2.5G line rate minus protocol overhead.
