Computer Platform Requirements Desktop computer equipped with a PCIe 2.0/3.0 x4, x8, x16 slot
Computer Platform
  • Computer with PCI Express slot (x4, x8, x16)

For the best performance (5.0 Gbps), It should be installed in a PCIe Gen 2 compliant slot in the host computer.  Most computers have PCIe Gen 2 (5.0 Gbps) throughput on x4, x8 or x16 slots.
A PCIe Gen 1 compliant slot reaches up to 2.5 Gbps throughput
