Outstanding performance and reliability for
demanding server environments
Hitachi Ultrastar 36Z15
hard disk drives
Highlights
Rotational speeds of 15,000 RPM and average seek time as low as
3.4ms to help boost performance
Capacities of 36 or 18GB provide configuration flexibility.
Utilizes technologies such as Drive Fitness Test, load/unload, and
glass substrate disks to enhance reliability and robustness and to
prolong the lifespan of the drive.
Allows for greater speed and higher performance with online trans-
action processing (OLTP), online analytical processing (OLAP),
and other decision support applications such as Oracle*, DB2, and
Microsoft SQL Server* databases.
Ideal for integration with Customer Relationship Management and
B2B solutions.
Advanced drive technology
The Hitachi Ultrastar 36Z15 leads the
industry with the Ultrastar 15,000 RPM
disk drive family. Leveraging the award-
winning technologies that have generated
proven quality and high-performance,
Hitachi drives utilize powerful processors
and read/write channels, feed-forward
servo controls that improve seek and set-
tle times, and suspension dynamics that
enable better servo bandwidth, improved
mechanical stability, and faster speeds for
the new Ultrastar 15,000 RPM family.
The Ultrastar 36Z15 hard disk drive
combines fast seek times, large multi-
segmented buffers, a sophisticated
command queuing system, hardware
automation, and industry-leading data
rates to achieve outstanding I/O perfor-
mance. In addition, the Ultrastar 36Z15
employs a fifth-generation giant magneto-
resistive (GMR) head technology for an
areal density of up to 10.7 Gbits/sq. in.
Reliability features
Research and development teams are
responsible for developing 40 years of
award-winning storage technologies that
satisfy increasingly complex user require-
ments. The new Ultrastar 36Z15 builds on
this tradition.
To help ensure data protection, Hitachi
Ultrastar drives include exclusive report-
ing tools, such as Predictive Failure
Analysis* which signals potential drive
problems; Drive-TIP* which monitors
drives and avoids malfunctions; and Drive
Fitness Test which enables self-testing
and analysis.
Reliability is further enhanced with load/
unload technology and glass substrate
disks which provide a robust solution at
high rotational speeds.
Support for advanced appli-
cations and interfaces
The Ultrastar 36Z15 provides high data
throughput for data-intensive appli-
cations with the Ultra160 SCSI
(backward-compatible) interface.
Hitachi offers a five-year warranty on its
Ultrastar 36Z15 hard disk drives.
