DDS is historically the most reliable and durable technology ever introduced within the tape market. DDS is ideal for entry-level and small networks looking for higher capacities with lower cost of ownership. DDS is an affordable solution for unattended back ups. HP co-invented DDS technology and was the first company to expand its DDS offering into the 5th generation known as DAT-72. In addition to co-inventing the DDS technology, HP also co-invented DAT 72, DAT 160 and the latest generation of DAT-320. HP's DDS media portfolio is now the most robust within the industry offering DDS-1 90m thru DAT 320 with capacities of up to 320GB on a single cartridge.
