One x16 slot is fine. Two x8 slots are better when you need a RAID card and a NIC running at full speed at the same time. This Gen4 riser splits the bandwidth so both cards get what they need. No lane sharing, no throttling. Your SR250 V2 runs the way it was designed to. Slot it in and stop choosing between storage speed and network throughput
