Mention the actual speeds and type of drive hardware.  Perhaps there's a
caching issue that boosts apparent throughput at the start, then when
you empty the cache, you're slowed down to the throughput speed of the
drive.

I remember that when the first high speed UDMA hard drives came out.
People went "wow, 66 megabits a second."  Then found out only the first
burst came out that fast, the rest was slower.  Much slower.
