RE2 Hard drive, 320 Gb, 16MB cache
With 1.2 million hours MTBF, 5-year limited warranty, 3 Gb/s SATA technology, and enhanced vibration tolerance, WD RE2 drives offer an ideal combination of reliability, high capacity, and optimum performance for enterprise applications.
Superior reliability
Designed and manufactured to provide server-class 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 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)
Significantly reduces drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.
Rotary Acceleration Feed Forward (RAFF™)
Provides enhanced vibration tolerance by optimizing operation and performance when the drives are used in vibration-prone, multi-drive 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.
