Unless your OS writes contiguous files almost always, this is not a very
useful benchmark.  Disk performance depends on so many things, it is almost
impossible to get a meaningful benchmark.  The DMA rate is freqently such
a small part of disk bandwidth that it doesn't matter.  Some considerations
are:
	Seek time
	Rotational latency
	Operating system disk block buffering
	Seek and latency OS optimizations (only useful in a multiprocessing
		environment)

It is very obvious on my ATARI 8 bit w/810 that even short sessions on the
machine fragment the disk files across the disk, significantly increasing
the seek time in typical file access.  (The sound the 810 makes when it
is seeking makes it painfully obvious when it is doing so.)

I have found few OS's that allow contiguous files, and none of them wrote
them by default.
