Capacity and Transfer Rates

The Certance DAT 72 and DDS-4 autoloaders provide the following capacities and sustained data

transfer rates, depending upon the type and length of tape media used. These capacities and

transfer rates are based on an assumed 2:1 data compression rate. Uncompressed (native)

capacities are one-half these values

applications, including:

• Backup of high-capacity hard drives or disk arrays
