GENERAL DESCRIPTION
This chapter summarizes the general functions and key features of the Quantum
Fireball Plus AS 10.2/20.5/30.0/40.0/60.0 GB AT hard disk drives, as well as the
applicable standards and regulations.

2.5 PRODUCT OVERVIEW
PRODUCT OVERVIEWPRODUCT OVERVIEW
PRODUCT OVERVIEW
Quantum’s Fireball Plus AS hard disk drives are part of a family of high
performance, 1-inch-high hard disk drives manufactured to meet the highest
product quality standards.
These hard disk drives use nonremovable, 3 1/2-inch hard disks and are
available with the ATA interface.
The Quantum Fireball Plus AS 10.2/20.5/30.0/40.0/60.0 GB AT hard disk drives
feature an embedded hard disk drive controller, and use ATA commands to
optimize system performance. Because the drive manages media defects and error
recovery internally, these operations are fully transparent to the user.
The innovative design of the Quantum Fireball Plus AS hard disk drives
incorporate leading edge technologies such as Ultra ATA/100, Advanced Cache
Management, Shock Protection System™(SPS), Data Protection System (DPS)
and Quiet Drive Technology (QDT). These enhanced technologies enable
Quantum to produce a family of high-performance, high-reliability drives.

CAUTION:
CAUTION:CAUTION:
CAUTION: The maximum limits for physical shock can be exceeded if the
drive is not handled properly. Special care should be
taken not to bump or drop the drive. It is highly recommended
that Quantum Fireball Plus AS drives are not stacked or placed
on any hard surface after they are unpacked. Such handling
could cause media damage.
