Solution kanewolf May 13, 2016 You can't get that much bandwidth from a PCIe X1. There maybe such a card, but you can't get full bandwidth on all devices. From Wikipedia -- PCI Express 3.0's 8 GT/s bit rate effectively delivers 985 MB/s per lane, That could do 1 SATA SSD but not 2 and that leaves NO bandwidth for USB. Usually each of those devices (USB3 port, or SATA port) gets a PCIe lane.
