If you're using an HDD, it's nothing different. There aren't many HDDs that can be bottle necked by SATA 3 or USB3.0

But if it's an SSD, USB3.1 or PCIe would be the best

SSD is almost always faster because SSD uses electronic to read and save data. In HDD everything is rotating and you need to wait for specific position before system will write or read something from disk.
