I used one a couple of years ago to update the BIOS on an old PowerEdge server.

I had a shock with that same server a couple of months ago. It liveslived in my garage and the drives started failing at the same time that I was having networking problems. So I rushed out to the garage to try and save some data that I knew wasn't backedup.

When I arrived at the server with my external hard drive, it took me several minutes to understand that it really didn't have a USB port anywhere cry
