Don't forget to take into account some speed gauges give you results in bits per second, other in bytes per second... I can't speak for USB sticks, but just about anything should be faster than optical drives. Well, USB 1.0 hosts or drives might be a bit slow. As you say, seek time, spin up and down time, reading difficulties, etc., all make optical drives slower to install from. As a comparison, I found an install from RPM files on a hard drive (local, or network), did a complete basic install in a bit over 15 minutes. But, the process often took over an hour if I used optical media. Installs from optical media only ran quicker on some drives and computers. I'm guessing the install routines can't access every DVD or CD drive at full speed (variations in UDMA modes for drives and hosts, etc.). -- (This computer runs FC7, my others run FC4, FC5 & FC6, in case that's important to the thread.)
