Wd Blue 4Tb Desktop Hard Disk Drive - 5400 Rpm Sata 6Gb/S 256Mb Cache 3.5 Inch - Wd40Ezaz

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 ship with a 2-year limited warranty.

Easy Backup And Upgrade

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

Technology To Help Protect Your Data

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