The higher standard in storage
Expand your PC with WD Blue drives, available in various storage capacities specifically designed for desktop and all-in-one PCs.

Boost PC performance
Give your PC a new boost by combining a WD Blue hard drive with an SSD. This way, you achieve maximum access speed while enjoying up to 6 TB of storage capacity.

Planning for the future
Enhanced technologies have increased storage demands. Digital cameras that record Ultra HD videos at a resolution of 4K and 30 frames per second require a lot of storage space. With a 6 TB hard drive, managing these data volumes is a breeze.

Trust WD
The legendary reliable WD Blue drives are designed, built, and tested for a long hard drive life.

Easy data backup, quick upgrade
The software "Acronis True Image WD Edition," available as a free download, can clone drives and back up your operating system, applications, settings, and data.

Technology to protect your data
NoTouch ramp load technology parks the read/write head in a safe position away from the drive's surface to protect your data.
