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. 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.
