Product Description WD40EZRZ

Recommended use
WD Blue storage is tested and recommended for use in desktop and All-in-One PCs, notebooks and external enclosures.

Improve PC Performance
Pair a larger capacity drive with an SSD to give your desktop a performance and storage boost. The SSD maximizes speed of data access, while the WD Blue drive stores up to 4TB of movies, games, files, applications and more.

Upgrade and Backup with Ease
WD hard drives come with free access to WD Acronis True Image. Our downloadable software quickly copies all your existing data to your new drive – without reinstalling your operating system. Backup and restore functions make it easy to save and retrieve your personal data.

Plan for the Future
With better technology comes bigger storage needs. 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 4TB drive.
