  • Engineered for maximum speed; WD VelociRaptor, the newest member of our unique class of 10,000 RPM SATA hard drives, combines a SATA 3 Gb/s interface and 16 MB cache, to deliver performance that’s up to 35% faster than its speedy older brother. Performance enthusiast systems, workstations, and low-end servers. Western Digital also offers a 5-year limited warranty on their VelociRaptor 300GB hard drive. Combined with the top of the line service and support, you’ll never have to worry about your lightening fast hard drive.

    Key Features of the Velociraptor Drive:

    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 percent faster than the previous generation WD Raptor drives, but they also beat out all other competitors in the field.

    Rock-solid Reliability – Designed and manufactured to mission-critical enterprise-class standards to provide enterprise reliability in high duty cycle environments. With 1.4 million hours MTBF, these drives have the highest available reliability rating on a high capacity SATA drive.

    Double the Capacity – State-of-the-art technology packs twice the capacity per disk compared to its older brother WD Raptor resulting in 300 GB of high-performance storage space in this enterprise-class 2.5-inch drive. (Not compatible with notebook computers)

    IcePack™ Mounting Frame – The 2.5-inch WD VelociRaptor is enclosed in a 3.5-inch enterprise-class 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.

    SecurePark™ – Parks the recording heads off the disk surface during spin up, spin down and when the drive is off. This ensures the recording head never touches the disk surface resulting in improved long-term reliability and increased drive protection when the chassis is moved.
