AMCC Applied Micro Circuits Corp.

At this week�s Macworld Conference and Expo�, Applied Micro Circuits Corporation (AMCC) (NASDAQ: AMCC) will showcase its hardware RAID storage expertise with the 3ware Sidecar, an external RAID storage solution for the Apple� Mac Pro� and Power Mac G5 with PCI Express workstations. Offering storage capacities of up to three terabytes and RAID 5 write and read speeds up to 200MB per second, the 3ware Sidecar is ideal for pro video and audio, high-end graphics, digital photography storage and other capacity-hungry applications. Visitors to booth S2431 will see 3ware Sidecar product demos which will focus on its seamless integration into the Mac environment. �As a photographer, it is critical for me to protect my digital assets, as well as to have adequate capacity,� said Graham Welland, a Portland, Oregon-based amateur photographer. �I was struggling with multiple external FireWire� drives that required manual backups for protection. My reseller, MacPac, recommended the 3ware Sidecar both for its performance and fault tolerance. I now use hardware RAID 5 for a much higher level of data protection, all in a smaller enclosure. My performance now matches my Quad processor Mac and I have plenty of room to grow.� Seamless Integration with High Performance Apple Workstations The 3ware Sidecar hardware RAID storage system is a desktop, external SATA II RAID solution that seamlessly integrates with the Apple Mac Pro and Power Mac G5 workstations. The 3ware Sidecar features an intuitive management software suite that simplifies the configuration, management and monitoring of the storage solution. Additionally, the Sidecar�s two meter Multi-lane� SATA cable enables four lanes of high speed 3Gb/s SATA traffic to travel from the PCI Express RAID controller to the 4-bay external enclosure. �The performance and capacity capabilities of AMCC�s 3ware Sidecar xSATA solution offer new storage flexibility to the Mac space especially for users who are restrained by the prohibitive cost of fibre channel at the very high end and by the performance limitations of USB, FireWire and eSATA-attached products at the low end,� said Scott Cleland, director of marketing at AMCC Storage. �The 3ware Sidecar provides true hardware RAID storage for the creative Mac user who demands high performance, capacity and RAID 5 data protection.� 3ware Sidecar Availability and Special Macworld Discounts AMCC�s 3ware Sidecar is available through AMCC�s worldwide network of distributors, VARs and direct market resellers.
