Purpose of creating smaller segmented stream f4f files?

Question

What the purpose behind creating smaller individual segmented stream f4f files instead of just creating a single large f4f file?
If I removed the SegmentDuration and DiskManagementDuration parameters from the event.xml file so I can create a single f4f file, would there be any issues with streaming or performance? 
<Event>
  <EventID>cfhs</EventID>
  <Recording>
    <SegmentDuration>400000</SegmentDuration>
    <DiskManagementDuration>3</DiskManagementDuration>
  </Recording>
</Event>
TO
<Event>
  <EventID>cfhs</EventID>
  <Recording>
          <FragmentDuration>4000</FragmentDuration>
  </Recording>
</Event>

Answer 1

There should not be any issue with streaming or performance if you choose to create single f4f file. The concept of smaller segment files is for DiskManagment to work so that anyone can manage thier disk space better.
