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.
