All of this is true, but the time it takes to seek across a disk is still only 
a few ms. If you consider latency as "time to seek across so many MB", then 
seek times are actually improving considerably. Consider:
Hard disk: 6ms to seek across 200GB (.03 ms/GB)
DVD: 125ms to seek across 2.2GB (56 ms/GB)
CD: 95ms to seek across 325MB (290 ms/GB)

As you can see, the penalty of a seek in data terms is three orders of 
magnitude higher for DVD than for a modern hard disk.

You will not get better performance on your hard disk by using UDF.
