Used | OWC Tested

1.2 Million Hours MTBF
World's Fastest SATA Drive


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, 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.

Key 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 16MB 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.
