Western Digital today 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. 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 (ms). WD Raptor 150 GB (model WD1500ADFD) hard drives are currently shipping in volume. Estimated retail pricing for WD Raptor is $ 299.99 USD.

Western Digital Corp. today 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.

"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."

Performance and Reliability of SCSI at Significantly Less Cost

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 (NCQ), 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 (ms).

The enterprise-class mechanical and electronics platform of WD Raptor is
designed to meet the 24×7 demands of the enterprise environment. Continuing to
be the world’s most reliable SATA hard drive, 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.
