Data density difference on a track? From its name, this test would be
writing a block much larger than the on-drive buffer and should be
limited by the rate at which the drive can write to whole tracks on a
platter, and seek between nearby tracks. More data per track = fewer
seeks.
Another thing that could be limiting might be file fragmentation on the
drive. The partition I used has had little written to it ever.

My U10 does file, IMAP, apache, and print server duty most of the time.
It provides a decently responsive 1600x1200 15 bit GUI when needed.
These things must have been ~$5K engineering or financial workstations
originally.
