Tape drive/media compatibility
For optimum performance and storage capacity, use tape cartridges that match your drive's format,
and normally use only one cartridge per day. Ideally, use:
• HP's DAT 320 cartridges with DAT 320 tape drives
• HP's DAT 160 cartridges with DAT 160 tape drives
The compatibility between drive models and cartridges is summarized in Table 8 on page 50.
Capacities assume a compression ration of 2:1.
NOTE:
Old tape formats are more abrasive than later generations and using older tape formats can reduce
the life expectancy of the tape drive.

DAT 320 tape drives and encryption
Your HP StorageWorks DAT 320 tape drive includes hardware capable of performing data encryption
at full speed while writing data, and decrypting when reading.
Encryption is the process of changing data into a form that cannot be read until it is deciphered,
protecting the data from unauthorized access and use. DAT 320 tape drives use the strongest version
of the industry-standard AES encrypting algorithm to protect your data (IEEE P1619.1-2007 compliant
GCM-128-AES-256).
To make use of this feature you need:
• A backup application that supports hardware encryption
• DAT 320 GB media; no hardware encryption will be performed when writing earlier generations
of tape
