WD2500SD - Western Digital Caviar 250GB 7200RPM SATA 7-Pin 8MB Cache 3.5-inch Hard Drive

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 does not compare to the extreme environment in an always-on, high duty cycle RAID system. What is 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.
