Overview

Get incredible storage capacity!

Expand your PC's storage capacity with WD Blue hard drives, a line designed specifically for desktop and all-in-one PCs. The WD Blue family now offers up to 8TB of storage capacity. Combine a larger capacity hard drive with an SSD to increase the performance and storage capacity of your desktop PC. While the SSD maximizes data access speed, the WD Blue hard drive can store up to 8 TB of movies, games, files, applications, and more.

Prepare your storage for the future

As technology becomes more advanced, more storage capacity is needed. Cameras recording ultra high definition video in 4K resolution and at 30 frames per second require massive storage capacity. With this hard drive allowing you to store up to 281.25 hours of 4K video, managing all these media files is a breeze.

Easy upgrade and backup

WD hard drives come with free access to WD Acronis True Image. This downloadable software quickly copies all your existing data to your new hard drive, without reinstalling your operating system. With the backup and restore features, you can easily back up and recover your personal data.

    Impeccable

    Hard drive received quickly and well packaged.
    I had initially mistakenly ordered an unavailable hard drive; after a phone call to customer service, in 5 minutes, the problem was solved by sending another equivalent model, available and at the same price or even a little cheaper...

    An efficient hard drive

    Good read and write speeds, without noise
    Plenty of capacity for storing photos and office work, and for sharing the risk of data loss with the main hard drive

    Good record

    A good drive, for the moment at least. At 7200 rpm, it's a little noisier than the WD20EZRZ model I had previously.

    WD Blue 2Tb

    So far, the hard drive seems very efficient and easy to use. Very slight noise when writing/reading, almost imperceptible.

    HDD for my NAS

    I gave this HDD to my son for his NAS. His choice was driven by excellent word-of-mouth reviews from users.
