I would guess that the SGI machine is showing these results because of
either A) caching or B) RAID or C) hardware cache or D) other special
hardware.  In any case, the Cheetah drives themselves, to my knowledge, do
not have a sufficient media transfer rate to sustain more than about
18MB/s.  IOW, the drive is maxed out at 18MB/s, so be happy.  It's much
faster than the average hard drive that maxes out at a media rate of 10MB/s
or less.
