...The controller has little to do with seek times. It should also be noted
...that for many applications, average seek time has almost nothing to do
...with performance, either!

Did I say anything about seek times?  The IW test measures performance
in a yet-unpublished way.

...For most applications, DATA TRANSFER RATE is much more important. This is

Agreed.  I changed the interleaving from 3 to 2 and data xfr went from
165 KB/s to 250 KB/s.

...Your absolute fastest possible data rate will be had with a synchronous
...SCSI controller running at full speed with a SCSI drive. I haven't seen one

True, but that doesn't address my problem.  I have an ST-506 drive.

...	4) Anybody have experience with other brands?

I've been running a Rodime 203E with an early Adaptec RLL controller
with excellent results for nearly two years.  However, no one should use
any HD with an RLL controller that is NOT certified for RLL formatting.

Your treatise on HDs was undoubtedly very informative, but my purposes
would have been served better had you answered my questions.  :-)
