Currently I am using a razer blade stealth hooked up to my razer core with a gtx 1070. I was curious as to whether increasing my current 256 g ssd with an external ssd (through one of my laptops usb 3.0 ports) would affect data transfer rates from my graphics card to laptop via thunderbolt 3. In other words, does usage of one port affect the speed of another port in a laptop?
