The HP StorageWorks DAT 72 tape drive is the
fifth generation of HP's popular DDS tape drives, built on the success of four
previous generations of DDS technology and providing unprecedented levels of
capacity, reliability and cost of ownership. The DAT 72 delivers a capacity of
72 GB on a single data cartridge and a transfer rate of 21.6 GB/hr (assuming a
2:1 compression ratio). The StorageWorks DAT 72 tape drive is the perfect choice
for small and medium businesses, remote offices, and workgroups.

Automated Head Cleaning: HP DDS drives
benefit from an automatic head cleaning "sweeper" that can be used during the
write or read recovery procedure to dislodge debris from the tape path and
recording heads and drive. This feature reduces the need to use a DDS cleaning
cartridge for manual cleaning.
Compression: DDS uses built-in hardware
compression using the 'DCLZ' data compression algorithm. Data compression is
host-selectable with the default that compression is turned on. Typical data
compression is 2:1, but actual compression depends on the type of data being
compressed and can be more or less than 2:1.
Compatibility: HP's extensive
compatibility testing program assures that HP StorageWorks DAT drives work with
leading servers, operating systems, and backup applications -- and not just
those sold by HP. HP DAT drives work seamlessly in many environments, making
them especially suitable if you have a mixed system environment.
