The Digital Audio Tape (DAT) drive used in the Workgroup Servers 8150 and 9150 is from Hewlett-Packard, model HP C1533A DDS-2. It supports 60m and 90m DDS Media Recognition System cartridges in addition to the new 120m Digital Data Storage-2 cartridges.
The specifications given below are based on the following general assumptions:
- Media must conform to the DDS Media specifications and not be damaged or faulty.
- The drive and media must remain within their respective operating and non-operating environmental specifications.
- The drive is in good operating condition.
- Read-after-write rewrites are used as necessary on writing.
Performance (DDS-DC Mode)
Capacity:
60 meter tape (DDS-1) 2.6 GB (typical)
