  Not quite.  Maintaining BTrees is CPU intensive.  I'd be happy with
a linear directory structure (like ProDOS) but with greatly increased
throughput.

  But the Berkeley Fast Filesystem is FAST.  REALLY FAST.  That's what
I'm after.  The BFFS takes into account drive parameters like head
latency, rotation time, rotations/second, etc to calculate exactly how
to lay stuff out on the drive.  In a sense, it's always adjusting the
interleave for optimum performance.  It also does some other highly
smart things (like blocks bigger than 512 bytes) for increased 
throughput.
