I only looked up the drive specs this morning, after having
thought Quantum made only 5400 and 7200 drives. That was pretty much
the only explanation I could think of (RPM). But I were to do
something like two 'dd if=blah of=/dev/null bs=65536' on files from
each drive simultaneously, I should still be able to hit close to the
maximum throughput, no?
