Western digital's raptor enters the enterprise storage market. (Storage Networking).Western Digital is entering the enterprise hard drive market with an Enterprise Serial ATA See SATA. Serial ATA - Serial Advanced Technology Attachment (ESATA) product called the WD Raptor. The new hard drive offers systems builders and storage vendors enterprise-class specifications: 1.2 million hours MTBF (Mean Time Between Failure) The average time a component works without failure. It is the number of failures divided by the hours under observation. MTBF - Mean Time Between Failures (Mean Time Between Failure) and 10,000 RPM (1) (Revolutions Per Minute) With electric and electronics devices, RPM measures the rotational speed of the motor's spindle. Floppy disks rotate at 300 RPM, while hard disks rotate from 3,000 to 15,000 RPM. , 5.2 milliseconds (ms) average seek time. Combined with an SATA (Serial ATA) A serial version of the ATA (IDE) interface, which has been the de facto standard hard disk interface for desktop PCs for more than two decades. The original Parallel ATA (PATA) interface was launched in 1986. interface, Western Digital designed a new, enterprise-class mechanical platform for the WD Raptor hard drive to meet the 24x7 demands of the enterprise environment. With its WD Raptor, Western Digital applies its high-volume design and manufacturing principles and economies of scale from its ATA (1) (AT Attachment) The specification for IDE drives. See IDE. (2) See analog telephone adapter. ATA - Advanced Technology Attachment business to an enterprise-class platform. The result is an ESATA hard drive with a significant cost advantage over SCSI SCSI in full Small Computer System Interface Once common standard for connecting peripheral devices (disks, modems, printers, etc.) to small and medium-sized computers. SCSI has given way to faster standards, such as Firewire and USB. devices. SATA offers system-level benefits in the enterprise environment, including point-to-point configuration, which utilizes the full bandwidth of each drive interface in a networked environment; scalability; hot-plug support for system design flexibility; and advanced error detection for data integrity. The hard drive is currently being shipped to vendors and will initially be shipped in a 36 GB capacity. In addition to its 5.2 ms average seek time, 10,000 RPM, and 1.2 million hours MTBF, data throughput is 150 MB/second from the SATA interface. The performance roadmap for SATA extends up to 600 MB/second, ensuring a reliable standard for storage providers and customers in the years ahead. www.westerndigital.com |
