WD Doubles WD Raptor Capacity to 150 GB

Western Digital Corp. announced that it has doubled the capacity of its next-generation 10, 000 RPM WD Raptor enterprise Serial ATA (SATA) hard drive to 150 GB and has increased the performance of the popular drive with additional features for server and networked storage applications.

Enterprise storage system vendors are increasingly embracing SATA hard drives as a reliable and cost-effective choice for servers and storage systems. When WD originally introduced the WD Raptor - its first SATA drive - in 2003, approximately 14 percent of hard drives used in multi-user applications were SATA technology, according to Gartner. The market research firm expects that portion to grow to 19 percent in 2005 and 30 percent by 2009.

The new, 150 GB WD Raptor maintains its high performance in servers and networked storage, where rotational vibration from multiple spinning hard drives robs performance, with its RAFF (Rotary Accelerometer Feed Forward) technology. The next-generation drive also offers best-in-class random I/O performance with native command queuing, which increases performance by intelligently ordering multiple simultaneous read and write commands, which is common in demanding, multi-user workloads such as servers. Sixteen MB cache furthers the drive's ability to serve and record data quickly for multiple users. The drive offers an average seek time of 4.6 milliseconds.

The enterprise-class mechanical and electronics platform of WD Raptor is designed to meet the 24x7 demands of the enterprise environment. WD Raptor is reliability-rated at 1.2 million hours MTBF (mean time between failure) in high duty cycle environments and is backed by a five-year warranty.
