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.
Key Features
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.

Frequently Asked Questions
| Q: |
Regular 7200 RPM desktop drives run fine in RAID environments; why do I need these drives?
| | A: |
Unlike regular desktop drives, WD RE2 hard drives are engineered and manufactured to enterprise-class standards and include features such as time-limited error recovery, Active Power Save, and RAFF that make them an ideal solution for RAID.
| | Q: |
What is time-limited error recovery and why do I need it?
| | A: |
Desktop drives are designed to protect and recover data, at times pausing for as much as a few minutes to make sure that data is recovered. Inside a RAID system, where the RAID controller handles error recovery, the drive needn't pause for extended periods to recover data. In fact, heroic error recovery attempts can cause a RAID system to drop a drive out of the array. WD RE2 is engineered to prevent hard drive error recovery fallout by limiting the drive's error recovery time. With error recovery factory set to seven seconds, the drive has time to attempt a recovery, allow the RAID controller to log the error, and still stay online.
| | Q: |
Don't I need SCSI data integrity For RAID environments?
| | A: |
These drives include 32-bit CRC error checking for all bits transmitted: command, data, and status and error checking to compare the data read back from the hard drive to the data originally written to the hard drive.
