Western Digital RAID Edition hard drives are the worlds most reliable server-class
SATA drives. With up to 1.2 million hours MTBF (RE2), 100% duty
cycle, 5-year warranty, up to 3.0 Gb/s SATA technology, and best-in-class
vibration tolerance, WD RAID Edition hard drives offer the best combination of superior
reliability, high capacity, and optimum performance for enterprise applications.
- SATA 300 MB/sec Interface (SATA II 3Gb/sec)
- 16 MB cache buffer size
- 7200 rpm
Superior reliability - Designed and manufactured to server-class standards to provide best-in-class enterprise reliability in high duty cycle
environments, these drives have the highest available reliability rating on a high-capacity drive.
Fast - With a next-generation SATA interface, up to 3.0 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:
- Audio/video media applications
- E-mail, database, web and file servers
- Network attached storage
- Scientific computing
- Life sciences
- Video surveillance
- Enterprise backup
- Document/image management
- Call centers
- Other demanding write-intensive applications
