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. 

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 up to 300 GB of high-performance storage space in this enterprise-class 2.5-inch drive. 

Ultra-cool operation – WD VelociRaptor consumes 35% less power than the previous generation of WD Raptor. 

IcePack™ mounting frame – The 2.5-inch WD VelociRaptor is enclosed in a backplane-ready 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. 

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.
