Maxtor ATLAS 10K III Product Manual

Setting the Standard

Introducing Atlas™10K III-Ultra320, the next generation Maxtor SCSI hard

disk drive providing full implementation of all mandatory and optional

Ultra320 SCSI interface features as defined in T10/SPI-4 rev. 9 draft standard.
These features include Adaptive Active Filtering (AAF), Packetization and
Quick Arbitration and Selection (QAS). Adaptive Active Filtering is a Maxtor
technology innovation that allows the drive to adapt to changing system

configurations and components while optimizing signal quality. This trans-

lates into lower error rates, easier integration, and increased bus efficiency

for optimal system performance. Ultra320 SCSI provides the highest ever

data bus bandwidth and is designed to handle the most demanding

enterprise server applications.

Best-Fit Enterprise Applications

Enterprise computer users will now have faster, more reliable data transfer

rates for optimal use in: multi-stream video and audio, data warehousing

applications, web servers, RAID applications, large file transfers, non-linear

editing, high-end graphics, electronic cinema, scientific data processing,

video servers, image processing, high definition play back, super

computer, and 3D animation.

Proven Full Inter-operability

The Atlas 10K III-U320 has proven full inter-operability

with major SCSI and SCSI RAID controller man-

ufacturers and it is backwards compatible

with prior SCSI interface standards.

Features and Benefits

Exceptional Performance

10,000 RPM, 4.5 ms seek time, large 8 MB cache buffer,
and peak 55MB/sec sustained data throughput. Atlas 10K
III-U320 offers 320MB/sec bus speed at industry leading
acoustic levels.

Exceptional Value

18.4GB/platter leads the way for the next generation of

SCSI drives. Higher data densities allow for higher reliability
and customer value. Atlas 10K III-U320 comes in 18.4GB,

36.8GB and 73.6GB capacity points with SCA (80-pin) or

WIDE (68-pin) interfaces.

SCSI Investment Protection

Atlas 10K III-320 has an automatic SCSI mode configuration
for U320, U160, Ultra2, Ultra, and Fast SCSI interfaces. It is
backwards compatible with prior SCSI interfaces standards.

Superior Reliability

To ensure flawless and consistent performance,
the Atlas 10K III-U320 drive features Maxtor’s breakthrough
Shock Protection System. SPS protects the drive from
mistreatment during handling and integration. For systems
integrators, SPS III results in fewer returns, lower total
cost of ownership, and satisfied customers. Data Protection
System, Thermal and Shock Sensors, S.M.A.R.T. Compliance
features are also included in the Atlas 10K III-U320 to ensure
the highest data and system reliability possible. We confi­dently stand behind the Atlas 10K III-U320 with a five-year
warranty.

Atlas 10K III–U320 and the Need for Speed

Maxtor continues to innovate and provide state-of-the-art
solutions to its customers. Ultra 320 SCSI widens
Maxtor’s SCSI leadership.

• Ultra 320 SCSI is the latest evolution of SCSI and takes

drive performance and reliability to the next level.

• As a rule of thumb, Bus Bandwidth needs to be 4X the

drive throughput to attain optimal system performance–
Ultra 320 SCSI makes it possible!

• Best-in-Class HDD max sustained interface transfer rates:

1999—28 MB/sec, 2000—42 MB/sec, 2001—55 MB/sec

• One Atlas 10K III drive can sustain 55 MB/sec peak data

rate throughput. Therefore, as few as three drives can

saturate an Ultra160 bus

limiting your system

performance.

• Ultra 320 SCSI provides optimal system performance,
extending your system advantage beyond 2003.

Atlas 10K III-Ultra320 provides all the advantages of the
Ultra320 SCSI standard. Features like: free-running clock,
training pattern, skew compensation and Adaptive Active
Filtering (AAF), Packetization provide unsurpassed data
and signal integrity. Quick Arbitration and Selection (QAS)
and Flow control optimize system performance. These
features are only available with the Ultra320 SCSI stan­dard and the Maxtor Atlas 10K III-Ultra320.

Adaptive Active Filtering–the Maxtor Advantage

Maxtor’s Atlas 10K III-U320 AAF implementation improves
signal integrity and as a consequence maximizes system
performance. Signals
with AAF are crisper
and have a better
peak-to-peak ampli­tude definition. AAF
enhances electrical
signal margins
reducing the nega­tive effect of signal

losses in back-planes

and cables.
