STORAGE NETWORKING WORLD HONORS QUANTUM VIRTUAL TAPE CUSTOMER WITH
"BEST PRACTICES IN STORAGE" AWARD

MetLife Investors Recognized by IDG's Computerworld for Their
Strategic Deployment of Storage Solutions to Meet Critical Business
and Compliance Objectives

SAN JOSE, Calif., Nov. 3, 2004 -- Quantum Corp. (NYSE:DSS), a global
leader in storage, today announced that MetLife Investors has been
recognized for its implementation of Quantum's DX-Series Disk-based
Backup System by Storage Networking World -- a conference co-owned by
Computerworld and the Storage Networking Industry Association (SNIA)
-- as one of the winners of the "Best Practices in Storage" Awards
Program. The award honors organizations that have applied exemplary
storage solutions to provide strategic advantage to their enterprise.
MetLife Investors was recognized for their storage achievement during
a special awards ceremony at Storage Networking World (SNW) 2004, held
last week in Orlando, Florida.

A wide range of IT end-user companies and organizations responded to
an initial "call for nominations," which was originally announced to
multiple industry audiences, including Computerworld subscribers
responsible for storage solutions. Finalists were evaluated by a panel
of judges based on case study submissions that profiled the company,
its IT department and storage challenges, as well as the application
deployment details, summaries of the key technology used and
measurable solution outcomes.

"Storage has become an essential business function for Fortune 500
companies as well as large enterprises globally, and the success of
this year's SNW conference is proof of that," said Ron Milton,
executive vice president for Computerworld. "This year's 'Best
Practices in Storage' Awards Program recognizes companies like MetLife
Investors who have elevated storage from a technology department
business function to a strategic initiative for senior-level
executives."

A co-winner in the "Industry Regulation Compliance and Corporate
Governance" category, MetLife Investors has combined a storage
infrastructure consisting of systems and management software from
various market-leading vendors including Quantum with sound business
practices and IT policies designed to meet service level agreements
and corporate compliance goals.

"Backup, restore and archive of data are my key focus areas for
compliance with corporate service level agreements and external
regulations," said Jesse Correll, manager of IT infrastructure for
MetLife Investors. "Adding virtual tape technology has increased my
backup reliability to over 99 percent, enabled me to shave about five
hours from my daily backup time and made data restores almost
instantaneous."

Quantum has invested considerable time researching the impact that
compliance will have on its customers, such as MetLife Investors,
within the IT department. Quantum believes the increase in corporate
governance brought on by the need to comply with these regulations is
no different than any other business process changes to which IT has
had to respond and that compliance begins with a solid backup,
recovery and archive foundation.

"MetLife Investors is an excellent example of a company that is both
setting solid management policies around compliance while planning for
necessary storage infrastructure changes," said Rob Pickell, vice
president of worldwide marketing for Quantum's Storage Systems
Business Unit. "By adding a virtual tape storage layer based on
Quantum's DX-Series products between his primary disk and archive
tape, Mr. Correll is meeting his service level agreements and after
just a few critical restores has realized the significant value of
this technology."

Quantum's DX-Series Disk-based Backup System emulates a tape library
and seamlessly integrates into existing backup environments without
changes to policies or procedures. Supported by every major backup
software vendor, the DX-Series provides user definable virtual tape
drives and cartridges to meet data center requirements. Optimized for
extremely fast and reliable backup and restore operations, the
DX-Series offers redundant and hot-swappable components and delivers
up to 64 TB (raw) capacity and up to 2 TB/hr performance.
