The exploding growth of enterprise data storage puts tremendous pressure on IT managers, who must accommodate ever-greater volume with ever-tighter budgets. This increased need for enterprise storage, coupled with the decline in IT budgets, creates a need for reliable, low-cost solutions. Enter Serial ATA (SATA), a new interface developed with enterprise storage in mind. Some hard drive companies design desktop-class hard drives with the SATA interface, but WD is going one better. To meet the demands of enterprise storage, Western Digital is the only company to combine an enterprise-class hard drive with the SATA interface to meet all the demands of the enterprise environment - reliability, performance, and reduced cost.Serial ATA is poised to replace Parallel SCSI in the mid-range, but only if there's a drive that can meet the performance and reliability requirements of that market. That drive is the WD Raptor! The WD Raptor is a new class of hard drive that matches SCSI performance and reliability and provides simplified connectivity, all at 30 percent less cost than Parallel SCSI drives.
