Because desktop drives offer high capacity at a lower-than-SCSI cost, an unprecedented number of

RAID systems are being designed around desktop drives. But life in a desktop computer doesn’t compare to the extreme environment in an always-on, high duty cycle RAID system. What’s needed is a drive engineered to thrive in a high-intensity RAID system while still offering traditional desktop value.

That drive is the WD Caviar RE. Designed and manufactured to enterprise-class standards,

WD Caviar RE drives provide enhanced reliability in a 24x7, high duty cycle environment. In addition, they offer a RAID-specific time-limited error recovery feature that improves compatibility with RAID adapters. WD Caviar RE hard drives are ideal for RAID server applications such as video surveillance, enterprise backup, document management, scientific computing, and similar demanding storage environments.

Product Benefits

!

!

!

!

!

!

Reliability in high duty cycle environments – utilizing enterprise-class manufacturing processes, these drives are designed with enhanced reliability in a 24x7, continuous duty environment.

RAID-specific time limited error recovery – improves compatibility with RAID adapters and prevents drive fallout caused by extended drive error-recovery processes.

8 MB cache – provides a higher percentage of cache hits and significantly faster time to data than industry-standard 2 MB versions.

Fluid Dynamic Bearing (FDB) technology – improves hard drive reliability; reduces heat, vibration, and noise.

Improved power controller – consumes less power and generates low heat.

Data Lifeguard Tools ™ – software utility that works in conjunction with the embedded

Data Lifeguard ™ features (including shock protection, an environmental protection system, and embedded error detection and repair features) to make hard drive installation, management, and diagnostics simple and worry-free.

SATA-specific Features

!

!

!

FlexPower ™ – connector technology that accepts power from either industry-standard or new SATA power supplies.

Hot plug support – allows swapping of hard drives without having to power down the system or reboot; promotes system design flexibility, data availability, and serviceability.

Backplane compatibility – uses the SATA industry standard connector which includes alignment ears and 3-stage electrical mating sequence, designed specifically for backplanes and hot pluggability.

!

SATA latching connector – provides a secure connection between the hard drive and the cable connector via a locking latch mechanism.

Recommended: Western Digital's Serial ATA cable with SecureConnect ™ provides a 500 percent stronger cable-to-drive connection than first-generation SATA hard drives and cables; for use with Western

Digital SATA drives only.

IMPORTANT: Because of the time-limited error recovery feature, this product is intended for server applications and is not recommended for use in desktop systems.
