Western Digital VelociRaptor 300GB Hard Drive
 |
Engineered for maximum speed. |
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 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.
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.
Ideal for performance enthusiast systems, workstations, and low-end servers
