 From an obviously biased standpoint (I did the original testing for the ESDI
 controller and ran the benchmarks) I can say that I was impressed with the
 controller.  After getting all of the bugs out, that is.  It's interesting to
 note that we were running a couple of test machines (a 386/25 and a 286/20)
 with XENIX using SCO's benchmark's (read: beat the hell out of the machine
 and disk drive) for a week straight -- 24 hours a day -- and didn't have a
 single failure!  The machine was running at that time, and I brought the
 machine down and ran fsck on the drive to make sure that we didn't have a
 subtle bug in the caching algorithm.  Worked fine.

  No.  The controllers look like an ST-506.

 Good question.  I think not, but am not sure.
