I tried the same on my Everex Step 386/25, copying a 34Mbyte file to /dev/null.
This was using the 2322 ESDI controller and the Wren V ESDI drive.
I got 435 kbytes/sec. (it was also with AT&T Unix, not SCO)

So ESDI users should not feel like they missed a great opportunity by not
starting off with SCSI. I agree that SCSI may be better from a conceptual
point of view, but ESDI in a PC (single user, not more than 2 disks needed,
etc.) performs more than well enough.
