Reliability and performance: the first 15K RPM enterprise

hard disk drive designed to deliver 1.4 million hours MTTF*

with leading IOPS performance

The Atlas 15K II Strengths

The Atlas 15K II SCSI drive is one of the industry’s fastest and reliable

15K RPM hard disk drive, with average seek times as fast as 3.0ms,

maximum sustained data transfer rate of 98MB/sec, and designed for

a 1.4 million hours MTTF*. The Atlas 15K II drive can manage the most

demanding I/O-intensive and high-bandwidth applications with supe-

rior reliability and adaptability. Maxtor’s intelligent drive technology,

MaxAdapt, allows the Atlas 15K II drive to adapt to various system designs

and conditions for ease of integration and maintains

optimal performance.

Maxtor MaxAdapt technology
offers the following key features:

Intelligent MaxAdapt features

• Adaptive Bias Estimation (ABE)—
Maintains consistent performance by
adjusting the bias applied
to the actuator

• Virtual Cache Lines (VCL)—
Allows dynamic assignment
of cache segments

• Adaptive Active Filtering (AAF)—
Improves signal integrity

• Rotational Vibration Compensation
(RVC)—Monitors and corrects for
external vibration

Reliability

• Improved S.M.A.R.T. and
self-diagnostics

• State-of-the-art manufacturing
test processes

• Multiple temperature tests

Performance

• Anticipatory read and write streams—

Minimizing hardware latency

• Opportunistic pre-fetch—

Uses latency between commands to
read ahead, improving performance

• Auto Read mode—

Improves random and multiple
sequential stream performance

Best-fit enterprise applications

• OLTP

• SAN environments

• NAS environments

• High-performance workstations

• 3-D animation

• Scientific data processing

• Economic modeling

• Data mining

• Web servers

• Audio/video

• Digital imaging

• RoHS compliant

For purposes of measuring drive capacity, a megabyte (MB) means 1,000,000 bytes, a gigabyte (GB) means 1,000,000,000 bytes. Total accessible capacity varies
depending on operating environment. Seek times are at nominal conditions and include settling. Specifications subject to change without notice.
* MTTF refers to the estimated mean time to failure based upon a statistical sample.
