G5: HFS+ vs UFS on large files

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.

HFS+ (Journaled) UFS
HFS+ (Journaled) 50 MB/s 30 MB/s
UFS 44 MB/s -
