I would like to connect my PC RAID server to US-16-XG Ubiquiti 10Gb switch using SFP+. I would prefer only a single port, and would like it to be PICe3.0 X4, so as to not to unduly burden my expansion slot requirements. PCIe X8 just isn't needed for a single-port card on PCIe3.0. But if the best card with a single port is PCIe3.0 X8 I can make it work. The Sonnet Presto Solo is $150, which seems a good deal. Does anybody here have experience with this card?
