If you're a hardware enthusiast then you will have no doubt come across Western Digital's Velociraptor range of high-performance hard drives. Well, these beasts have evolved!

- Killer speed SATA 6 Gb/s interface and 32 MB cache enhance the next generation 10,000 RPM WD VelociRaptor making it up to 15% faster than the award-winning previous generation.
- Monstrous capacity WD VelociRaptor SATA drives are available in capacities up to 600 GB, double the capacity of the previous generation.
- 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.
- Ultra-cool operation Consumes no more power than the previous generation WD VelociRaptor while offering double the capacity and higher performance.
- 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.
- Environmentally conscious In addition to being ROHS compliant, this generation of WD VelociRaptor is also a halogen-free design.
Manufacturer's Suggested Retail Price (MSRP) for the VelociRaptor 450GB (model WD4500HLHX) is $299 and the 600GB (model WD6000HLHX) is $329.
