Do you suppose that is because of the disk, the host adaptor
or something in the software?  I've been wondering over the
past couple of days whether the 3/80 uses the same SCSI and
Ethernet chips as the 4/60 (and 4/65?)

Still have to wait for data to fly under the head, although
that may not be the only thing effecting your disk
performance.
