  • Protecting your moments: The new generation of WD Black hard drives is equipped with Corruption Protection Technology (CPT), which helps to protect and limit the potential problem of data loss during power failure/power loss to the hard drive. Overall, CPT can save you time and money on your project
  • Efficient dual processing: When it comes to processing power, more is always better. WD Black features a dual core processor that offers twice the processing power to maximize drive performance
  • Upgrading your drive is easy: WD Acronis True Image, available as a free download on the WD Support site, enables you to copy all your data to a new drive so you don't have to reinstall your operating system to get all the benefits of a new drive
  • Recommended use: WD Black hard drives are tested and recommended for use in PCs, high-performance workstations, all-in-one PC's, gaming PC's, game consoles, home media PC's and notebook computers
