WD Blue 8TB Desktop Hard Drive (WD80EAAZ) – SATA 6Gb/s, 5640 RPM, 256MB Cache, CMR

The WD Blue 8TB (WD80EAAZ) is a 3.5-inch internal desktop hard drive for PC builders, gamers and home users who need affordable bulk storage. With 5640 RPM operation, a 256MB cache and CMR recording, it handles game libraries, media collections and backups reliably.

Add terabytes to your desktop without slowing it down.

Why Your SSD Shouldn’t Store Everything

Most modern PCs boot from a fast SSD, but SSD capacity is expensive per terabyte. Games, photo libraries, video projects and backups fill it quickly, forcing constant deleting and juggling.

The WD Blue 8TB solves this by adding 8TB of affordable storage. Keep your OS and active apps on the SSD and move large libraries to the hard drive. Its lower-RPM design runs quietly and coolly for always-available storage.

CMR Recording for Steady Transfers

CMR keeps write speeds consistent when copying large files, and the 256MB cache smooths everyday reads and writes.

Easy Upgrade for Any Desktop

The standard 3.5-inch form factor and SATA connection fit nearly every desktop case and motherboard, and Acronis True Image for Western Digital helps you clone or back up your system.
