If we were using Usenet rather than mailing lists, I would agree with your
position more-- article cross-posting would be handled without duplication of
resources, and newsreader software would handle xposting so that people only
read one copy, even if they are subscribed to both newsgroups.
This is not the case with mailing lists.
The reason why this thread isn't really appropriate to freebsd-hardware is
because it concerns how the filesystem architecture works in general, on any
type of device from a hard drive, to a floppy drive, to a USB pen device.

Sure. Try looking at:
zcat /usr/share/doc/smm/05.fastfs/paper.gz | less
zcat /usr/share/doc/papers/diskperf.ascii.gz | less
Kirk McKusick also wrote a book on this topic, if you want more information.
However, a point to consider is that if you do some benchmarks for yourself
using your hardware in the circumstances you care about, you will get better
numbers for your situation than you do looking at generalizations, averages,
or specific results from some other hardware being tested in some way that may
or may not resemble your workload.
