With 160 GB capacity and 12 MB/sec transfer rate, HP DAT 160 Data Cartridges offer the highest storage capacity and backup performance of DAT technology, extending the roadmap of the most successful tape backup product in history. New 'wide' format enables longer tape and greater capacity whilst still permitting backwards compatibility to DDS-4. DDS-4 and DAT 72 customers will still be able to read data written on older tapes, thereby protecting investment in older formats.
