If I'm reading that right, you're testing a 300MB file on a machine with
2GB of RAM.  You'll never get meaningful results from bonnie or any
filesystem performance measuring tool like that if you have a test file
that is less that the memory size of your computer.  Without checking, I
think the rule of thumb is to use 2*RAMSIZE as a base file size to work
with.

At least for longer life (ie less writes) the section about disk tuning
in http://www.NetBSD.org/docs/power-mgmt/index.html#hints might be a
good place to start.
