Engineered for maximum speed! WD VelociRaptor, the newest member of Western Digital's 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.

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 150 GB of high-performance storage space in this enterprise-class 2.5-inch drive.

Small form factor – This ultra fast 2.5-inch hard drive is engineered to fit into blade servers and other enterprise storage configurations. (Not designed for use in laptop or notebook computers)

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

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.

Ideal For: Blade servers, performance enthusiast systems, workstations, and low-end servers
