The Market
With the explosive growth of enterprise-
wide computing, the demand is increasing
for larger and faster departmental and
enterprise servers and performance
workstations. In this market, the award-
winning Quantum Atlas™ 3.5-inch hard
disk drive is the leader. Now the new
Quantum Atlas 10K II hard disk drive
continues the tradition with huge
capacity, incredibly fast performance,
and solid reliability.
The Industry’s Highest Performance:
10,000 RPM and More
With its blazing-fast 4.7 millisecond
(ms) seek time coupled with a 3.0 ms
rotational latency, large 8 megabytes
(MB) cache buffer, and 41 megabyte-
per-second (MB/sec) peak sustained
throughput, the Atlas 10K II drive
delivers the random I/O performance
and sequential throughput capability
demanded by data-intensive applications.
Available in capacities of 73.4 gigabytes
(GB), 36.7 GB, 18.4 GB, and 9.2 GB,
the Atlas 10K II drive is the optimum
choice for Windows NT or UNIX
enterprise and departmental servers, as
well as high-performance workstations
running 2D graphics, 3D video, and
other high I/O applications.
Quantum Quality and Reliability
To ensure flawless performance the first
time, and every time, the Atlas 10K II
drive features Quantum’s breakthrough
Shock Protection System II (SPS II)
that protects against mistreatment
during handling and integration. For
systems integrators, SPS II means fewer
returns, lower total cost of ownership,
and more satisfied customers. For
customers, it means one less thing to
worry about. In addition, we confidently
back every Atlas 10K II drive with a
five-year warranty. All are good reasons
why Quantum means quality.
