Western Digital WD VelociRaptor WD3000GLFS 300 GB SATA II Hard Drive

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)
IcePack™ 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 (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.
