Ready to excel in the most demanding server-class environments

Hitachi Ultrastar 146Z10 hard disk drives

Highlights

 Rotational speed of 10,000 rpm and average seek times as low as

4.7 ms provide outstanding performance

 Capacities of 146, 73, 36, and 18GB from a single server drive fam-

ily for unrivaled configuration flexibility and ease of integration

 First ever server-class drive to implement antiferromagnetically-

coupled (AFC) media, combined with advanced head/disk design, resulting in high reliability for today’s critical server-class environments

 Enhanced servo technology (Rotational Vibration Safeguard)

nullifies the effect of rotational vibration in multi-drive cabinets,

overcoming an industry hurdle to optimal server performance

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.

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*

sector formatting enables more data to be

stored per disk

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).

In addition, load/unload technology and

glass substrate disks increase reliability

of Ultrastar drives by providing a more

robust solution at high rotational speeds.

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

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.
