OK now this is from a ROM 01 12.5 Mhz 32 cache Transwarp GS with 8 Meg OctoRam 
card running under GSOS 6.0.1.  The Appletalk option on the Transwarp is active
and Twilight II is running in the background.  The SCSI card if you hadn't 
known is an Apple HS with DMA on.  The drive is a Quantum 120s.  I did 2 test.
The first is on partition to see if inside tracks are faster than outside.  
Test seems to confirm this.
