lct20 is a drive designed to enhance

and improve the end-user experience

• Lower Total Cost of Ownership.

Quantum’s exclusive Shock Protection

System II and Data Protection System

help deliver a lower total cost of

ownership by protecting against

physical damage, data loss, and

unnecessary drive returns

• Quiet Drive Operation. Quantum’s

new Quiet Drive Technology provides

a heightened user experience by

reducing the level of acoustics and

improving its quality

• Wide Range of Capacities. Available

with 10.0 to 40.0 GB capacity in a

3.5-inch form factor to handle a

Quantum Quiet Drive Technology

Quantum developed its exclusive

Quiet Drive Technology (QDT) to

provide users with the lowest possible

disk drive acoustics and best overall

sound quality from their drives. Through

innovative technology, QDT reduces

the drive noise by improving the sound

quality while at the same time reducing

the sound measurement.

Delivering Reliability

Like previous Fireball generations, the

Fireball lct20 takes reliability and data

integrity to an even higher level with

Quantum’s Shock Protection System II

(SPS II) and Data Protection System

(DPS). SPS II gives the user enhanced

protection against both operating and

non-operating shock. DPS verifies

essential functions in seconds to eliminate

costly and unnecessary drive returns.

Together, these systems deliver higher

reliability and improved data integrity,

while reducing drive returns and cutting

processing and replacement costs.

The Market

What the industry presently demands

from hard drives are reliability, quiet

operation, low total cost of ownership,

and the ability to support the most

popular applications: word processing,

sending and receiving e-mail, and

browsing the Internet. The Quantum

Fireball™ lct20, part of a family of

hard drives expressly created to

enhance and improve the end-user

experience, efficiently meets these

industry demands. Building on the

proven Fireball platform, the Fireball

lct20 drive uses advanced, integrated

electronics combined with numerous

design innovations to achieve a wide

range of capacity points, solid reliability,

and quiet operation all at very

competitive prices. Optimized RPM and

seek provide these benefits that the end

user truly values. As a result, these

drives are today’s premier value in

desktop storage for consumer and

business applications.

New Quantum-Developed Ultra

ATA/100 Interface

The new Quantum-developed Ultra

ATA/100 interface has a data transfer

rate of up to 100 megabytes-per-second.

With this leading-edge interface, end

users should be protected from

obsolescence for the next

several years.
