** The SCSI bus itself limits this speed, not the design of SDLT 600 tape drive or Super DLTtape II media.

Ultra 160 SCSI Interface

The Ultra 160 SCSI interface provides a low-voltage differential (LVD) mode running up to 160 MB/second and a single-ended (SE) mode running up to 40 MB/second.

NOTE: The host computer’s SCSI controller card may limit these speeds. To achieve the best performance, make sure the SCSI controller card can operate at 160 MB/second.

The tape drive automatically senses the SCSI bus mode and switches between LVD and SE accordingly. Although the tape drive defaults to LVD, it switches to SE if the SCSI bus operates in SE mode. For example, if the SCSI controller card is SE (or multimode set to SE), the tape drive automatically switches to SE mode. Also, if any device on the SCSI bus is SE, the entire bus switches to SE, including the tape drive.
