HP StorageWorks DAT Tape Drives User Guide 31
7 Use the correct media
For best performance we recommend HP branded media. Order online at:
www.hp.com/go/storagemedia. If you do not have internet access, refer to the User’s Guide on the
HP StorageWorks Tape CD-ROM for ordering information for tape cartridges and cleaning cartridges.
Data cartridges
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 72 cartridges with DAT 72 tape drives
• HP’s DDS-4 cartridges with DAT 40 tape drives
• HP’s DDS-3 and DDS-2 cartridges with DAT 24 tape drives
Although HP StorageWorks DAT tape drives are fully backward compatible, old tape formats are
more abrasive than later generations and using older tape formats can reduce the life expectancy of
the tape drive. The compatibility between drive models and cartridges is summarized in Table 2.
Shaded boxes show the recommended media for each tape drive. Capacities assume a
compression ration of 2:1.
NOTE: DDS-1 cartridges are not supported on any HP StorageWorks DAT drive.
