Digital Data Storage (DDS) is a magnetic tape storage format that is used to store and back up computer data on tapes derived from Digital Audio Tape (DAT) technology.
DDS-1 is the first DDS format developed by HP and Sony in 1989.
It has a tape length of 60 meters and a capacity of 1.3 GB (uncompressed).
The transfer rate is 183 kB/s.
In addition to DDS-1, a further "DDS-1"-format was subsequently developed, the DDS-DC.
This has a tape length of 90 meters.
Capacity was increased from 1,3 GB to 2,0 GB.
The transfer rate remains the same.
