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;
