So would I.  Last night I installed a ST02 ST296N in my Dell System 200
(286/12.5) and was suprised to see that my ST251-0 was constantly clocking
faster access times than the SCSI.  Using Coretest 2.7, I was getting
somewhere around 28-29ms for the 251 [who knows, maybe the people at Dell
were confused and gave me the 251-1...] and about 32-33ms for the 296.
I also got about 440KB/sec data transfer rate.  Strange.

The one thing that I thought might be the holdup was the 8-bit card (ST02)
that I installed with the drive.  Does Seagate make a 16-bit SCSI adaptor?
