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 • HP's DAT 72 cartridges with DAT 72 tape drives • HP's DDS-4 cartridges with DAT 40 tape drives The compatibility between drive models and cartridges is summarized in Table 5 on page 46. 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). 46 Use the correct media
