ESDI is an easy winner, if you compare 1 disk to 1 disk.  If you are
using more disks, SCSI provides the nice features of overlapped
operations.  2 disks, with seperate controllers, on the SCSI bus will
provide very near twice the throughput of 1 drive.  This is not the
case with ESDI.  Which is better really depends on wheter you care
more about overall throughput or single access times.
