RE3 Enterprise - SATA Hard Drives 500 GB, 1.2 million hours MTBF, 16 MB Cache, 7200 RPM
WD RE2 hard drives are the world’s most reliable server-class SATA drives in the market. With 1.2 million hours MTBF, 5-year limited warranty, 3 Gb/s SATA technology, and best-in-class vibration tolerance, WD RE2 drives offer the best combination of superior reliability, high capacity, and optimum performance for enterprise applications.
Superior reliability
Designed and manufactured to server-class standards to provide best-in-class 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, 3 Gb/s data transfer rate, native command queuing (NCQ), and 16 MB cache, these drives deliver optimum performance.
Low power
Active Power Save™ delivers best-in-class seek mode power consumption through an advanced WD firmware which conserves power in active seek modes without degrading performance.
RAID-specific, time-limited error recovery (TLER)
A feature pioneered by WD, significantly reduces drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.
Rotary Acceleration Feed Forward (RAFF™)
Provides best-in-class vibration tolerance by optimizing operation and performance when the drives are used in vibration-prone, multidrive systems such as rack-mounted servers or network storage.
Perpendicular Magnetic Recording (PMR)
WD RE2 drives employ PMR technology to achieve even greater areal density.
Ideal For
Servers, SAN/NAS, scientific computing, life sciences, video surveillance, enterprise backup, document/image management, audio/video media applications, and other demanding write-intensive applications.
