Booooooooooooooooooring :)

What probably happened is that the disk got fragmented, and the I/O got
less efficient.  That's why throughput went down.

These kinds of tests should usually be run on ramdisks if you want to
get the physical I/O variability down to a minimum.  These results are
stull valid, just think about it next time.
