Hitachi and Silicon Image to Showcase 3 Gb/s SATA Solution at Intel Developer Forum

SAN JOSE, Calif. and SUNNYVALE, Calif., February 28, 2005—Hitachi Global Storage Technologies (Hitachi GST) and Silicon Image, Inc. (Nasdaq: SIMG) today announced plans to conduct a 3 Gb/s Serial ATA (SATA) performance and interoperability demonstration at this week's Intel Developer Forum (IDF) in San Francisco, Calif.  Hitachi led the industry with its recent introduction of a 500 GB SATA drive, delivering 3 Gb/s data transfer rates and other performance-enhancing features.  The demonstrations in both the SATA-IO booth 623 and Silicon Image booth 322 at the IDF Technology Showcase highlight the performance capabilities offered by Hitachi's Deskstar 7K500 3 Gb/s drives and Silicon Image's new SteelVine™ architecture, which leverages a single 3 Gb/s SATA host connection to deliver up to 2.5 terabytes of readily accessible storage in an appliance-like solution that is simple, reliable, affordable and scalable.

The 3 Gb/s demonstration features Silicon Image's SATALink™ SiI 3124-2 four-port host controller with advanced SATA features connected via an external SATA connection to Silicon Image's SV2000™ storage appliance, which is the first implementation of the SteelVine architecture.  The SV2000 is loaded with five Hitachi Deskstar 7K500 3 Gb/s drives. When used in combination, the companies have demonstrated read and write performance over a single SATA link in excess of 230 MB/s.

"Hitachi's introduction of the world's first 3 Gb/s SATA drive exemplified how the company is innovating on behalf of its customers," said Becky Smith, Vice President of Marketing, Hitachi Global Storage Technologies.  "Our collaboration with Silicon Image will showcase the numerous benefits of 3 Gb/s SATA and underscore Hitachi's position as the hard drive performance leader."  Hitachi's 2.5-inch, 1.5 Gb/s SATA drives, which are also shipping in volume, will also be on display with Silicon Image at IDF.

"We are excited to be working with Hitachi to showcase the performance benefits of 3 Gb/s SATA technology," stated Mark Hartney, Silicon Image SATA evangelist and director of market development, storage products.   "The SV2000's SteelVine architecture is able to take full advantage of the 3 Gb/s bandwidth and fan out a single SATA host connection to five drives for simple, reliable, affordable and scalable storage that is applicable for a number of external storage applications in the SMB and consumer storage markets, including business application and information storage, e-mail storage, nearline storage, data backup and archiving, video editing and DVR expansion."

Hitachi's new series of SATA drives all feature single-chip, native SATA chipsets and Native Command Queuing (NCQ), which enables fast data transfer rates for performance-based applications.  The new 3 Gb/s data transfer rate on the Deskstar drives represents a doubling of the current industry-standard SATA interface speed.  The performance breakthrough is expected to benefit customers that require fast data access for bandwidth-intensive applications, such as digital video editing and PC gaming.

The SteelVine architecture helps users dramatically simplify adding reliable storage to any system.  Silicon Image's SteelVine architecture delivers enterprise-class features, such as virtualization, RAID, hot plug and hot spare, in an appliance-like solution that is easy to deploy.   Leveraging a standard SATA interface, SteelVine provides users with a consumer-oriented storage solution that does not require special O/S drivers or RAID software to load or configure. 

The Hitachi and Silicon Image SATA product demonstrations will also be featured at CeBIT 2005.  CeBIT, the world's largest information technology conference, takes place in Hanover, Germany, March 10-16.
