HP AP835B DAT 320 Tape Drive - 160 GB (Native)/320 GB (Compressed)

HP StorageWorks DAT drives are based on the Digital Data Storage (DDS) format. In fact, DAT is the most successful tape backup technology of all time with more than 18 million DAT drives shipped since its introduction in 1989, and with a current world-wide installed base of over 6 million drives. A number of vendors manufacture DDS format DAT drives, but HP has long been the market leader in DAT technology.
