LaCie Selects Silicon Image's SteelVine Storage Processor for eSATA Products

SUNNYVALE, Calif., August 1, 2005—Silicon Image, Inc. (Nasdaq: SIMG), a leader in multi-gigabit semiconductor solutions for the secure transmission and storage of rich digital media, today announced that LaCie has selected Silicon Image's SteelVine(™) storage processor for its external SATA (eSATA) products.  LaCie's new Biggest S2S announced at Digital Video Expo East leverages the SteelVine storage architecture to provide over 187 MB/s data transfer per unit at less than $2 per GB.  Because performance scales linearly, multiple units can be used for bandwidth-intensive applications such as multi-stream uncompressed high-definition video editing, CAD/MCAD applications and medical imaging. 

"The SteelVine architecture delivers simplicity, reliability, performance, scalability and host independence to the storage market, and we are very pleased that LaCie, a leader in multi-functional storage solutions, has selected SteelVine for their eSATA storage products.   SteelVine and eSATA deliver functionality and performance levels previously only available in enterprise products, with the ease of use of a consumer appliance," noted Alex Chervet, Silicon Image senior product marketing manager, systems marketing.  "LaCie has a strong worldwide presence, and the Biggest S2S furthers the trend we are seeing toward mass-market availability of eSATA and SteelVine-based solutions." 

SteelVine-based solutions operate at speeds up to 3.0 Gb/s, more than three times faster than 1394b and over six times faster than USB 2.0. Using a single SATA interface and cable, SteelVine delivers a sophisticated RAID solution that does not require special O/S drivers or RAID software to be loaded and configured on the host, which dramatically simplifies adding up to 2.5TB of fast, reliable storage to any system.

"LaCie is excited to work with Silicon Image to deliver a next-generation SATA II RAID solution called the Biggest S2S, a compact five-bay tower that's ideal for fast real-time storage of uncompressed video files," stated Emanuela Boila, LaCie product manager.  "We chose to work with Silicon Image because they're an innovation leader in the SATA marketplace. This innovation coupled with our expertise in delivering cutting-edge hard drive solutions benefits Mac and PC users looking for large capacity RAID at a fraction of the cost for traditional systems."

Silicon Image is partnering with OEMs worldwide to address their customers' unique storage needs and to drive the adoption of eSATA-based solutions.  Silicon Image offers a full range of SteelVine products that range from SteelVine storage processors to SteelVine subsystems ideally suited to build high-performance solutions for video and audio editing and production, medical imaging, surveillance systems, DVRs, network backup and general purpose storage for consumers, professionals and small and medium businesses.
