Western Digital VelociRaptor WD3000GLFS

• 300GB
• 10000 RPM
• 16MB Cache
• SATA 3.0Gb/s

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.

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 percent 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 300 GB of high-performance storage space in this enterprise-class 2.5-inch drive. (Not compatible with notebook computers)

IcePackâ„¢ mounting frame - The 2.5-inch WD VelociRaptor is enclosed in a 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. (This drive is not backplane compatible.)

Rotary Acceleration Feed Forward (RAFFâ„¢) - Optimizes operation and performance when the drives are used in vibration-prone, multi-drive chassis.

NoTouchâ„¢ 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.
