    The Mammoth tape drive provides storage capacities of up to 20 gigabytes (GB) native on a single 170m data cartridge. The Mammoth tape drive is available as an internal model that can be installed into an enclosure (shown on the right) or as a tabletop model housed in its own enclosure (shown on the left).

  • Page 8: Available Scsi Configurations

    Available SCSI configurations Available SCSI configurations The Mammoth tape drive is available in the following fast SCSI-2 configurations:  Narrow, single-ended  Wide, single-ended  Wide, high-voltage differential (HVD)  Wide, low-voltage differential (LVD) The LVD tape drive uses an LVD interface that is Ultra and Ultra2 SCSI compatible.
