THUNDERBOLT 2 HARD DRIVE ENCLOUSER DRIVERS

Beyond that, while it's true the XPS 13 can be had with 6 cores now, the fact remains that it's still a 15W U Series CPU that is optimized for low power, not something like a 45W H Series CPU optimized for high performance, as found in the XPS 15. If you can at least temporarily attach an external display to your eGPU, I suspect you'll notice an improvement there. In terms of your issue, you might want to create a new topic for better visibility given that this is totally unrelated to the original thread here, but if you're using an eGPU to accelerate content on the built-in display rather than having external displays connected to the eGPU's own outputs, then that would definitely introduce a performance hit because the system has to send data to the eGPU for rendering and then receive it back over Thunderbolt to display it on its built-in display. An eGPU obviously is not a storage device and would communicate with the host system over PCIe, so that setting would not be available for your eGPU, nor would it affect available Thunderbolt bandwidth in any way. Thanks in the write cache option applies only to actual storage devices attached via USB, and it's a setting changed on the hard drive device in Device Manager. Should I be seeing other references to Thunderbolt in the manager? Are there other places where I can control Thunderbolt or see how it is being controlled? In Device Manager, the only reference I see to Thunderbolt is the Controller under System Devices.

My sense was that the problems then were due to old drivers on the machine when I received it.

I am going to contact OWC next about this, but I do know I had problems when I first got the XPS, and had to send it back to Dell. I believe the Thunderbolt software, firmware, and driver are up to date. The Thunderbolt Control Center recognizes the enclosure and says it is connected. The drives in the enclosure are very slow, slower than drives connected (through the dock) to USB 3 ports. I have a fairly new connected to an OWC Thunderbolt dock, which in turn is connected to an OWC Thunderbay 4 drive enclosure.
