WD VelociRaptor™
3.5-inch SATA Hard Drives
300 GB, 3 Gb/s, 16 MB Cache, 10,000 RPM
The evolution of 10,000 RPM SATA technology.
The WD Raptor has evolved! PC enthusiasts’ favorite 10,000 RPM SATA drive is now faster than ever.
Model: WD3000HLFS
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.
Key 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% 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.
