Intel Ethernet Network Adapter I225-T1

Lost my 10 G Intel X550T1 in a lightning strike. Running a 2.5 network is a cost cutting compromise. SSD write speeds at 300mps instead of 550mps - fast enough for home use. Compatible with Truenas Core and handles large packets with Ecc properties as needed by the system.

I bought this to upgrade my home server and backup systems to 2.5Gbps. I use it with a Qnap 2.5Gb switch and my transfer speeds have doubled! I don't need 10Gb or higher but when I need to transfer the occasional tens of gigabytes, I'll be happy. I currently use this on my TrueNAS SCALE machines and my friend uses it with his TrueNAS Core and SCALE devices. It was plug n play simple for me. No issues.

IMO Intel makes the best chips for network adapters, the Windows drivers are well supported. My only complaint is the cost, which seems excessive for an adapter that’s slower than 10Gbps.
