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.
