  • The original
    WD Blue drives are designed and manufactured with the proven technology found in WD's original award-winning desktop hard drives.

  • More options
    These drives are available in a broad range of capacities, cache sizes and interfaces so you can be sure there's a drive that's the perfect fit for your system, in more ways than one.
  • 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.
  • SATA or PATA interface
    While SATA has become the industry standard interface, WD continues to manufacture desktop drives with a PATA interface for unique or legacy systems.
  • Tested for compatibility
    We perform tests on hundreds of systems and a multitude of platforms in our FIT Lab™ to give our customers confidence that our drives will work in their systems.
