These numbers are kind of screwed up. I find it hard to believe that a Seagate Cheetah 10k disk only gets this kind of performance. I am probably going to retire the machine that this disk is in, and find something a bit better.

Some more unbelievable numbers. It wouldn't surprise me here if there was some major caching going on. The machine itself has 8gb of RAM in this situation.
Children see throughput for 1 initial writers = 20867.79 KB/sec
