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-3 stores up to 12 gigabytes of uncompressed data.
The tape length of the DDS-3 format is 125 meters.
It achieves transfer speeds from 0.7 MB/s to 1.5 MB/s.
DDS-3 uses Partial Response Maximum Likelihood (PRML).
