Great performance and reliability provide high value for a wide
range of performance desktops, workstations, and PC servers

IBM Ultrastar 9ES Hard Disk Drive

Highlights

Enhanced performance

Average seek times of 7.5 ms and mini­mum sustained data rates of 8.3 MB/sec
provide high performance for a variety of
PC, workstation, and server applications.

Industry-standard capacities

At 4.5 and 9.1 GB, the Ultrastar* 9ES
provides the storage required by a broad
range of data-intensive applications.

Extremely low power dissipation

Through efficient electronic design and a
new integrated LSI chip, the Ultrastar 9ES
provides the industry’s lowest 7200 RPM
idle power, helping to improve reliability and
ease of integration.

Proven IBM reliability

With a reputation for quality and reliability,
IBM SCSI drives provide excellent cost-of­ownership benefits to system integrators.

Low acoustics

With acoustics matching IBM’s previous­generation 5400 RPM drives, the Ultrastar
9ES provides excellent human factors
qualities for workstation and desktop PCs.

Exceptional data protection

S.M.A.R.T. (Self-Monitoring Analysis and
Reporting Technology) protocol support
alerts systems of impending drive failure
and helps ensure data availability.

Leading drive technology

As a member of the IBM Ultrastar family of
disk drives, the Ultrastar 9ES is designed to
provide a reliable, cost-effective storage
solution for a wide range of workstations,
high-performance desktop systems, and
LAN servers running Internet/intranet,
CAD/CAM, and multimedia applications.

The Ultrastar 9ES achieves its high level of
reliability, performance, and affordability
by leveraging IBM’s development and
implementation experience in advanced
disk drive technologies. These include
Magnetoresistive Extended (MRX)
advanced head technology, No-ID* sector
formatting, the Partial Response Maxi­mum Likelihood (PRML) digital data
channel, and a new integrated LSI chip.

MRX advanced head technology
increases areal density and reduces the
number of disks and heads required for
a given capacity. No-ID sector format­ting increases storage capacity by
eliminating overhead caused by the
duplicate storage of each data sector’s
ID field onto the disk, which thereby
creates more available disk space for
data. PRML enables higher areal
densities and significantly enhances
the drive’s overall performance by
increasing media-to-buffer and buffer
transfer rates.

IBM and Mitsubishi have developed an
integrated LSI chip that incorporates a
microcomputer, hard disk controller, and
flash memory in a single chip. This design
helps to increase performance, reduce
power usage, and enhance reliability.

SCAM-2 (SCSI Configured
Automatically)-compliant

Ultrastar 9ES drives support the imple­mentation of SCAM-2. This support may
increase user productivity by simplifying
and improving the installation and configu­ration of SCSI disk drives.

Flexible interfaces

To accommodate a wide range of system
requirements, Ultrastar 9ES drives are
available with an Ultra-SCSI interface in
multiple configurations: 50-pin Single­ended, 68-pin Single-ended Wide, and
80-pin SCA-2 Single-ended Wide.
