It's pretty interesting though, as PCIe, SATA, Thunderbolt and USB are all on a path to converging. Thunderbolt 2, or 3 if you have it, has good support for external graphics and is your best bet at this point for generic device support. I'm not aware of a generic USB to PCIe translation 'driver' for any OS, but I'd be surprised if people aren't working on it. Most of the solutions I've seen have limited application in terms of PCIe cards that they support mostly because of a lack of driver support - graphics over usb is poorly supported by anyone at this point storage devices have the most support. I'm not aware of any commercial 3.1 products that have general pcie support. USB 3.1 (which is electrically compatible with thunderbolt 3) has more options, but is only starting to roll out. If you have USB 3.0 there are limited commercial options - things like the ASUS XG Station 2 which uses 2 usb connections for its external pcie Nvidia card, but accepts other cards (apparently just graphics): The inclusion of an internal USB 3.0 connection provides the added benefit of compatibility to future USB 3.There are some on the market now, like this one for thunderbolt 2: The card will supply 5V, 900mA to the USB 3.0 port, allowing more and more external devices to operate without the need of an additional power source.
In addition to providing considerably faster transfer rates, the PEXUSB3S11 USB 3.0 card draws power from the computer power supply through a SATA style power connector - a perfect solution for systems that have a limited number of LP4 connectors available. Providing data transfer speeds up to 10x faster than USB 2.0, this PCI Express USB 3.0 card enables you to access your data and transfer files faster than ever, by adding one internal USB 3.0 port and one external USB 3.0 port to your PCI Express-equipped PC.įeaturing a native NEC PCI Express host controller chipset, the new USB 3.0 standard supports transfer rates of up to 5Gbps, while still providing connectivity and support for the older USB 2.0 (480Mbps) and 1.1 (12Mbps) devices.
