RE2 SATA Hard Drive 750 GB, 16 MB Cache, 7200 RPM
1.2 million hours MTBF. Best-in-class vibration tolerance. 5-year limited warranty. Just three of the reasons why WD RE2 drives are the world's most reliable SATA drives.
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.
Key Features
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.
High capacity - Up to 750 GB of storage packed with server-class features and low cost-per-gigabyte value.
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.
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.
