Reliability features
The Ultrastar 146Z10 family of server-class
drives is the first of its class to
incorporate our storage breakthrough
technology—antiferromagnetically-
coupled (AFC) media. Informally known
as “pixie dust”, this technology sand-
wiches a three-atom thick layer of
ruthenium, a precious metal, between two
magnetic layers on a disk. AFC tech-
nology provides greater stability of the
recording media, enhancing reliability.

Drive Fitness Test enables drive self-
testing and analysis—for more robust
system management. To help ensure
data protection, Hitachi Ultrastar drives
include exclusive reporting tools, such
as Predictive Failure Analysis* (to signal
potential drive problems) and Drive-TIP*
(to monitor the drive temperature and
avoid malfunctions).

Advanced drive technology
Introducing the sixth generation of
Ultrastar 10,000 rpm disk drives. The
Hitachi Ultrastar 146Z10 drive family offers
high quality and superior performance.
These drives feature more powerful pro-
cessors and read/write channels to excel
in server-class environments.

These drives feature more powerful pro-
cessors and read/write channels to excel

To achieve maximum I/O performance,
the drives combine fast seek times,
large 8 MB multi-segmented buffers, a
sophisticated command queuing algo-
rithm, hardware automation, and superior
data rates (825 Mbps). Ultrastar 146Z10
drives include new servo technology
(Rotational Vibration Safeguard ”RVS”),
employed to counteract the effects of rota-
tional vibration that commonly occur in
multi-drive cabinets. They also employ
fifth-generation giant magnetoresistive
(GMR) head technology to double areal
density from previous generation drives
(26.3 Gbits/sq. in.) and boost perfor-
mance. In addition, highly efficient No-ID*

In addition, load/unload technology and
glass substrate disks increase reliability
of Ultrastar drives by providing a more

Outstanding environmentals
Hitachi Ultrastar drives provide extremely
quiet operation. The tri-laminate drive
cover reduces both idle and seek acous-
tics while an enhanced spindle motor
driver enables smoother commutation for
less noise. Moreover, the Ultrastar 146Z10
delivers an outstanding power efficient
design.

Support for advanced appli-
cations and interfaces
cations and interfaces
Hitachi Ultrastar drives provide high data
throughput for data-intensive applica-
tions with a choice of 2 Gbit Fibre
Channel and Ultra320 SCSI (backward-
compatible) interfaces. The Ultra320
SCSI adds greater speed, reduced over-
head, improved diagnostic capabilities
and data protection.
