SE == Single-ended

You are using a single-ended terminator, which limits the SCSI bus to 40
MB/s bandwidth.  Try a LVD terminator which should give you the full 160
MB/s.  But remember that this only increases the speed at which data can
burst over the SCSI bus, not the speed at which the disk can access the
media.
