Don't be. The (theoretical) transfer rate of USB 3.0 is nearly as high as 3rd-generation SATA, and certainly high enough that it's not going to impact the speed of a platter-based mechanical hard drive.

USB is has always been worse than its rated speed though for a variety or reasons. It requires the CPU to be the bus master, it is only half duplex, and the data transfer is not isochronous. This is why firewire 400 would always beat USB2 in the real world, despite it being rated 80 Mbits slower.

It actually could matter in a spinning disk because of the CPU overhead for a usb device. I've seen slower transfer rates from the usb 3 port vs the thunderbolt port on the same drive often.
