Desktop 3.5-inch Hard Drives
WD Blue

WD desktop hard drives have been tested and are recommended for consumer RAID applications when using the drives only in a RAID 0 (Stripe) or RAID 1 (Mirror) configuration.
For other RAID applications please consider using WD Red hard drives.

A modern classic
WD Blue storage is designed and manufactured with technology found in WD’s original award-winning desktop and mobile hard drives. WD Blue sets the baseline for everyday storage by consistently delivering improved performance over previous generations while successfully maintaining WD’s quality and reliability for over six generations. The difference is that our colors never fade, generation after generation.

Your power of choice
WD Blue is available in a broad range of entry-level capacities, cache sizes, form factors and interfaces so you can be sure there’s a drive that’s the perfect fit for your system. However, not all hard drives are created equally and for your applications that demand more, WD gives you the power of choice.
 
Drive with confidence
We perform tests on hundreds of systems, configurations, and a multitude of platforms in our FIT Lab™ to give our customers the confidence that our drives will work in their systems for the ultimate compatibility. WD Blue allows you to use our drive with confidence, knowing that our storage advancements such as NoTouch™ Ramp Load technology are proven and reliable everyday solutions.

The WD advantage
WD puts our products through extensive Functional Integrity Testing (F.I.T.) prior to any product launch. This testing ensures our products consistently meet the highest quality and reliability standards of the WD brand. WD also has a detailed Knowledge Base with more than 1,000 helpful articles as well as helpful software and utilities. Our customer support lines have longer operational hours to ensure you get the help you need when you need it. Our toll-free customer support lines are here to help or you can access our WD Support site for additional details.

Easy upgrade
Acronis True Image, available as a download on the WD Support website, 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 Blue storage is tested and recommended for use in desktop and All-in-One PCs, industrial applications, notebooks, and external enclosures where capacity is not needed. For additional capacity, look at WD Green capacity storage drives.

SATA or PATA, the choice is yours
While SATA has become the industry standard interface, WD continues to manufacture desktop drives with a PATA interface for unique or legacy systems.
