In the early 90's, I was a huge fan of ESDI drives.  The largest
I ever dealt with were 1.3 Gig Hitachi's.

The larger-capacity drives generally had higher data rates and most
WD-based PC-clone controllers couldn't handle them.  I think the largest
were targetted towards ESDI-based RAID arrays.  They were built like
Bentley's - solid!

The ESDI interface was sort-of like a slightly scaled down SMD interface.
The drives did seek counting, and there were medium-level commands that
the controller could send to a drive.
