Do you realize that you didn't really answer either of the questions?

Well, I realized it only after hitting the Submit button.

The USB drive is plugged into the back of my Apple Thunderbolt Display, which is in turn connected to my Mac with a thunderbolt cable. Checking the System Profiler, as you suggest, I see that it has a speed of "up to" 480 MB/sec no matter where it is plugged in, even the keyboard.

That TM backup would have been an incremental backup, which I believe happens hourly. If you only changed one meg of data during that time, nearly any data transfer method common in the past 10 years would do that in under 10 seconds.

Yes, I am aware. I changed 8GB just to make TM do some actual work.

Thanks for sharing your ideas -- they did help me to understand what was going on. The drive now backs up my internal SSD with speed to burn, and I am very happy.
