Yes, you have described USB. The newer storage-specific transfer modes for USB3 try to do better, but it's still a shared bus and requires lots of CPU "assistance" to do just about anything. And there are lots of systems that have some USB3 and some USB2 ports - accidentally plug your external SSD into a USB2 port and start copying lots of data, and the system can just about appear to be hung.
