Another question to ask would be this:

UFS and ext4 allow certain options for initializing a file system.
It's possible that those options have been set in a certain way,
for example, to have UFS run with suboptimal settings. I thin dd
operates on file system level here (instead of "on bare device"),
so those FS settings _might_ have an impact on the results.
