WD VelociRaptor
Enterprise Hard Drives
300 GB, SATA 6 Gb/s, 32 MB Cache, 10,000 RPM
Bigger. Faster. Hungrier.
The PC enthusiasts' favorite 10,000 RPM hard drive is still the fastest, most dangerous carnivore around - now with an ultra-fast 32 MB cache and SATA 6 Gb/s interface and twice the capacity of previous generations.
Features:
Overview:
WD VelociRaptor hard drives deliver maximum speed and reliability for performance enthusiast systems, workstations, and low-end servers. With a superbly engineered combination of 10,000 RPM spin speed, SATA 6 Gb/s interface and a 32 MB cache, these drives are truly an evolution in performance.
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 less idle power and uses similar active power as 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.
