ellarienTime to pull 6Gb of files off the Butterfly laptop onto a new 1Tb portable drive: about three hours.
Time to copy the same files from the portable drive to the Dragonfly laptop: about ten minutes, including time to change the permissions and ownership on the files.
I'm not sure how much of the discrepancy was read vs write times, and how much was the difference in the laptops, which is three or four years and a couple of Gb of memory; I'll get more idea of that when I finish copying the other 10Gb or so of files I want, and run a backup.
