WD Blue Desktop

The Higher Standard In Storage

Boost your PC storage with WD Blue drives, the brand designed just for desktop and all-in-one PCs with a variety of storage capacities.

Improve PC Performance

Give your desktop a performance and storage boost when you combine your hard drive with an SSD to maximize speed of data access and a WD Blue drive for up to 6TB of additional capacity.

Plan for the Future

With better technology comes bigger storage needs. Digital cameras that record ultra-high definition video at 4K resolution and 30 frames per second require a ton of storage. Handling all that media is a snap with our 6TB drive.

Trust in WD

With legendary reliability, WD Blue drives are designed, tested and built to last, and ships with a 2-year limited warranty.


Acronis True Image WD Edition software, available as a free download, can clone drives and backup your operating system, applications, settings and all of your data.


NoTouch Ramp Load technology safely positions the recording head off the disk surface to help protect your data.
