WESTERN DIGITAL Digital Raptor 74GB SATA 16MB 10000RPM

SATA Hard Drives
74 GB, 1.5 Gb/s, 16 MB Cache, 10,000 RPM

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.

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.
