Copying really large files CD sized images between two harddisks, both Seagate ST3160023AS. HFS+ wins this one easily. I don't have two UFS partitions though one measurement couldn't be made. Copying was made from/to empty partitions approximately 20GB offset from the start.
Columns are destination, rows source.
