Using Your Digital Data Storage (DDS) Tape Drive

DDS Tape Drive and Data Cassette Descriptions

DDS Tape Drive and Data Cassette Descriptions

This section describes basic information needed for using your DDS tape drive and data cassettes.

DDS Drive

Your DDS tape drive is either a DDS-DC (early or later model) or a DDS-2 tape drive with a 3.5-inch form factor, data compression, and a narrow sin- gle-ended SCSI interface. Both drives incorporate data compression capabil- ity and are high-capacity, high transfer-rate devices for data storage on tape. With compression, the DDS-DC drives can store up to 4 GB of data on a 90 meter tape and the DDS-2 drive can store up to 8 GB of data on a 120 meter tape.

Storage Capacities

The maximum storage capacities of different DDS drives with and without data compression are shown in the following tables;
