Hitachi Deskstar® 7K80

HARD DISK DRIVES

Features and Benefits

www.hitachigst.com

The 7K80 provides all of these enhancements to enable faster data access and better

power management to the system. The drive is also backward compatible for those

wishing to upgrade their storage of SATA 1.0 systems.

Hitachi Quality and Service

The Hitachi Deskstar 7K80 extends the company’s long-standing tradition of performance

leadership. Hitachi’s standardized features in desktop solutions enable fast transfer rates,

low power utilization and quiet acoustics.

Hitachi is dedicated to provide a breadth of hard disk drive solutions to satisfy all of

today’s demanding computing needs. Hitachi drives are backed by an array of technical

support and services, which may include customer and integration assistance.

A/V Streaming Feature Set

The Deskstar 7K80 is the second generation

Deskstar drive to enable the host system to

optimize storage of data. This is achieved

by Hitachi’s “Smooth Stream” technology

which gives the host control over the drive’s

error recovery process. This important ATA-7

Standards feature fine tunes the Deskstar to

record and play multiple standard definition

and high definition video streams.

Why Serial ATA 3.0Gb/s?

> 3.0Gb/s (300 MB/s) interface data rate

> NCQ (native command queuing)

> Staggered (delayed spin-up
