One Stop Systems OSS-PCIe-HIB25-x1-H PCIe x1 Gen 2 Host Cable Adapter

PCIe cable adapters install easily into your computer's PCIe slot. A PCIe cable can then be plugged into the cable connector on the adapter's front panel to extend the PCIe bus from the motherboard to an external device, like an expansion enclosure or storage device. The PCIe x1 adapter extends the PCIe bus at 500MB/s with extremely low latency because there is no conversion software.
