Western Digital Corp. has doubled the capacity of its next-generation 10,000 RPM WD Raptor enterprise Serial ATA (SATA) hard drive to 150 GB. The company has also doubled the cache and increased the performance of the drive with additional features for server and networked storage applications.
The new 150 GB WD Raptor uses RAFF (Rotary Accelerometer Feed Forward) technology to maintain its high performance in servers and networked storage, where rotational vibration from multiple spinning hard drives robs performance.
The drive is said to also offer best-in-class random I/O performance with native command queuing (NCQ), which increases performance by intelligently ordering multiple simultaneous read and write commands. 16 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.
"WD continues to lead the industry with the broadest enterprise SATA lineup: WD Raptor delivers enterprise reliability and performance, and the company's RAID Edition drives - WD Caviar RE and WD Caviar RE2 - deliver enterprise capacity and reliability," said Tom McDorman, vice president and general manager of enterprise storage for WD. "Building on customer demand and market adoption for enterprise SATA drives, the 10,000 RPM WD Raptor delivers the greatest performance and reliability of all SATA hard drives available."
The enterprise-class mechanical and electronics platform of WD Raptor is designed to meet the 24x7 demands of the enterprise environment. The 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.
WD Raptor 150 GB (model WD1500ADFD) hard drives are currently shipping in volume. The drive is available at the company's online store for an estimated retail price of $299.99.
