Some hard drive companies design desktop-class drives with the SATA
interface. To meet the demands of enterprise storage, WD is going one better.
WD is the only company combining a 10,000 RPM enterprise-class
mechanical platform with the SATA interface to meet all the demands of the
enterprise environment—reliability, performance, and reduced cost.

WD produces the world’s most reliable SATA drives. With 1.2 million hours MTBF, enterprise
duty cycle, 5-year warranty, next-generation SATA technology, and state-of-the-art vibration
tolerance, WD Raptor drives offer the best combination of reliability, high capacity, and
performance for enterprise applications.
Product Features
Reliable — designed and manufactured to enterprise-class standards to provide enterprise
reliability in high duty cycle environments. With 1.2 million hours MTBF, these drives have the
highest available reliability rating on a high-capacity drive.
Fast — with a next-generation SATA interface, 1.5 Gb/s data transfer rate, native command
queuing (NCQ), and 16 MB cache, these drives deliver optimum performance.
RAID-specific, time-limited error recovery (TLER) — a feature unique to WD, prevents
drive fallout caused by the extended hard drive error-recovery processes common to desktop
drives.
Rotary Acceleration Feed Forward (RAFF™)— optimizes operation and performance
when the drives are used in vibration-prone, multidrive systems such as rack-mounted servers
or network storage.
FlexPower™— connector technology that accepts power from either industry-standard or
new SATA power supplies.
