The delays in writes are due to the fact that Ubuntu uses journaling
file systems (as do some versions of Windows) which basically means that
the OS caches the writes, and then writes them to disk when it's got a
few spare seconds. The time delay can vary from a fraction of a second
to minutes on a very busy system.

The problems I have had relate more to not having permission to write to
the device at all. Which is bizarre. Sometimes it lets me and sometimes
it doesn't. Never worked that out yet.
