Quantum SDLT220

Overview

Quantum Super DLTtape™ incorporates multiple advances in technology, achieving huge increases in capacity and transfer speed. More importantly, this is the only architecture that provides a viable evolutionary path to further leaps in capacity and performance in the future, while maintaining compatibility with the world's huge installed base of DLTtape cartridges. This provides you the best possible protection for the long-term success of your investment in data storage solutions.

 

Benefits

  • Native capacity of 110 GB at 11 MB/s transfer rate
  • 2:1 Compression allows 220 GB at 22 MB/s
  • Technology designed to reach 2 TB capacity at 160 MB/s
  • Fully backward read compatible with DLTtape IV cartridges
  • Advanced Metal Powder Media allows the optical servo tracks onto the reverse side of the tape
  • 100% of tape's magnetic side freed up to record data
  • No need for magnetic pre-formatting
  • Laser Guided Magnetic Recording combines best of optical and magnetic technologies
  • Pivoting Optical Servo increases high duty cycle reliability
  • Magneto-Resistive Cluster Heads for the highest data density
  • High efficiency PRML Channel creates more tracks on the tape
  • Increased media capacity provides easier use and lower cost of ownership
