Well, I don't know much about the topic, but here is my $0.02.

ESDI uses two cables to connect the disk controller card and
the ESDI drives.  Yes, one for data and one for control.
However, you cannot put MFM drives on any ESDI controller.
They are electrically different.  Unlike SCSI, you cannot
daisy-chain ESDI drives and I don't see anything like ESDI
tape or ESDI CD.  If I buy my equipments all over again, I
will probably pick SCSI instead of ESDI, at least you are the
possibility to put more devices on the same controller. ;)
