About WD 1TB Internal Drive

The WD VelociRaptor 1TB 2.5" SATA Internal Hard Drive offer an unmatched combination of high performance and high reliability, perfect for workstations, high-end video and photo editing, low-end servers and performance enthusiasts' systems.

WD 1TB Internal Drive Features

  • Ultra fast: Designed around a 10,000 RPM spin speed, these SATA 6 Gb/s drives include a 64 MB cache and deliver the ultimate performance for photo and video editing
  • Rock-solid reliability: With 1.4 million hours MTBF, these drives have the highest available reliability rating on a high capacity SATA drive
  • High capacity: State-of-the-art technology delivers a balance of high performance and high capacity perfect for data-intensive workloads that require large amounts of storage such as video editing, 3D rendering and scientific modeling
  • Ultra-cool operation: Consumes less idle power and uses similar active power as the previous generation WD VelociRaptor, while offering higher capacity and performance
  • IcePack mounting frame: The 2.5" hard drive is enclosed in a backplane-ready 3.5" mounting frame with a built-in heat sink that keeps this powerful little drive extra cool when installed in high-performance desktop chassis
  • Pre-emptive Wear Leveling: Ensures reliability for applications that perform a high incidence of read/write operations at the same physical location on the disk
  • Advanced Format: Technology adopted by WD and other drive manufacturers as one of multiple ways to continue growing hard drive capacities. AF is a more efficient media format that enables increased areal densities
  • 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 also provides a halogen-free design
  • Rotary Acceleration Feed Forward: Optimizes operation and performance when the drives are used in vibration-prone, multi-drive chassis
  • Ideal for: High-performance computing, 3D rendering, digital content creation and editing, scientific computing and image management
