Quantum DLT VS80
The Quantum DLT VS80 fills the need for
reliable tape storage in a small package. The DLT VS80 offers the industry's
first half-high, 5.25-inch form factor and offers 40GB of native capacity (80GB
compressed) and a 3MB/second native transfer rate (6MB/second compressed).
Available as an internally configured unit, the DLT VS80 uses the standard
DLTtape IV media, and is backward read compatible with the popular DLT 4000 tape
format.
Features
- Native capacity of 40GB at 3MB/second
transfer rate
- 2:1 compression allows for 80GB
capacity at 6MB/second transfer rate
- Half-high, 5.25-inch form factor
- Read and write compatible with the
DLT1
- Read compatible with the DLT 4000
- Internal and external configurations
available
- Uses DLTtape IV media cartridges
