Premium Backup Technology for Small Business
The fourth generation product in the
DDS
roadmap,
Quantum
DDS-4
solutions maximize capacity and
performance
while
delivering
exceptional total cost of ownership.
Accounting for 80% of all entry-level
tape drive shipments, DDS is the most
popular format for tape backup and
archive in the small and medium
business market.
Reliability Through Innovation
The Quantum DDS-4 is designed for
reliability with a unique system of
protection called TapeShield. TapeShield
is a combination of an environmentally
sealed chamber for the head-to-tape
interface (HTI) and a sapphire media
cleaning
blade
which
work
in
combination to defeat the number one
enemy of tape, particle contamination.
Tapeshield increases data integrity and
enhances drive and media life.
The Fastest DDS-4 Available
Quantum DDS-4 features a 19.8GB/hr*
compressed transfer rate with 40GB
compressed capacity for fast backup
and restores.
Easy Integration
The Quantum DDS-4 is designed and
extensively tested to be backward
compatible with DDS-3, DDS-2 and
DDS-DC for both read and write
functions. This makes upgrades easy
without losing the use of previous
generation tapes or data.
