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 at 100% duty cycle, 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
up to 64 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
