Western Digital VelociRaptor:

Workstation SATA Hard Drives

WD VelociRaptor drives offer an unmatched combination of high performance and high reliability, perfect for workstations, high-end video and photo editing, low-end servers and performance enthusiast's systems. Comes with a 3.5-inch mounting frame for easy installation into today's high-performance systems and chassis.

WD Raptor has evolved! PC enthusiasts' favorite 10,000 RPM SATA drive is now faster than ever and available in a 300 GB capacity. Engineered for maximum speed, WD VelociRaptor combines a SATA 3 Gb/s interface and 16 MB cache, to deliver performance that's up to 35 percentage faster than its speedy older brother. With 1.4 million hours MTBF, these drives have the highest available reliability rating on a high-capacity SATA drive and are designed and manufactured to enterprise-class standards to provide enterprise reliability in high duty cycle environments.

Ultra fast. Designed around a 10,000 RPM spin speed, these SATA 6 Gb/s drives include a 64 MB cache and deliver the ultimate performance for photo and video editing.	Rock-solid reliability. With 1.4 million hours MTBF, these drives have the highest available reliability rating on a high capacity SATA drive. In addition, these drives feature a 5-year limited warranty.	High capacity. State-of-the-art technology delivers a balance of high performance and high capacity perfect for data-intensive workloads that require large amounts of storage such as video editing, 3D rendering and scientific modeling.

Product Features:

Killer speed. Built on the performance bloodlines of WD Raptor, these 10,000 RPM drives, with SATA 3 Gb/s interface, and 16 MB cache deliver mind-bending performance. Not only are they 35% faster than the previous generation WD Raptor drives, but they also beat out all other competitors in the field. Double the capacity. State-of-the-art technology packs twice the capacity per disk compared to its older brother WD Raptor resulting in up to 300 GB of high-performance storage space in this enterprise-class 2.5-inch drive. Ultra-cool operation. Consumes less idle power and uses similar active power as the previous generation WD VelociRaptor, while offering higher capacity and performance. NoTouch ramp load technology. The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit. Pre-emptive Wear Leveling (PWL). Ensures reliability for applications that perform a high incidence of read/write operations at the same physical location on the disk.

IcePack mounting frame. The 2.5-inch hard drive is enclosed in a backplane-ready 3.5-inch mounting frame with a built-in heat sink that keeps this powerful little drive extra cool when installed in high-performance desktop chassis. Rotary Acceleration Feed Forward (RAFF). Optimizes operation and performance when the drives are used in vibration-prone, multi-drive chassis. Advanced Format (AF). Technology adopted by WD and other drive manufacturers as one of multiple ways to continue growing hard drive capacities. AF is a more efficient media format that enables increased areal densities. Environmentally conscious. In addition to being ROHS compliant, this generation of WD VelociRaptor is also a halogen-free design. Ideal for: Power computing applications such as multimedia, video and photo editing, and maxed out gaming computers.
