NIC vs. USB

"A faster NIC (network interface card) will not affect how fast you are able to transfer files from your computer to your phone via USB. The speed of file transfer via USB depends on the USB version and the devices connected. According to an article, the USB transfer rates are as follows:

- USB 1.0: 1.5 Megabits per second (Mbps)
- USB 1.1: 12 Megabits per second (Mbps)
- USB 2.0: 480 Megabits per second (Mbps)
- USB 3.0: 5 Gigabits per second (Gbps)
- USB 3.1: 10 Gigabits per second (Gbps)

These speeds are theoretical and may vary depending on the actual performance of the devices. A faster NIC will only improve the speed of file transfer over a network, such as Ethernet or Wi-Fi."

So, if you do a lot of local file transfers, you'll want your LAN speeds to be as fast as possible. This is why people use 10GbE NICs and switches for.
