Western Digital Blue 4TB 3.5" SATA Internal Hard Drive

The Western Digital WD40EZAX is a 3.5 inch SATA internal hard drive that adds 4TB of dependable space to a desktop PC. It gives you room for an extensive media library, large project files, and daily backups without forcing you to juggle external drives or cloud subscriptions.

With a rotational speed of 5400 RPM, a 256MB cache, and a SATA III interface that supports transfer rates up to 185MB per second, the drive handles everyday tasks smoothly. Whether you are copying a batch of high-resolution photos, streaming stored movies to a home theater PC, or loading large game levels, the data flow remains consistent and responsive.

NoTouch Ramp Load technology keeps the recording head clear of the disk surface when the drive powers down, which helps reduce mechanical wear and extends the operational life of the drive. Advanced power management also lowers energy draw, a practical advantage for systems that run for long periods such as family PCs, small-business workstations, or home media servers.

Installation is straightforward. Western Digital includes access to Acronis True Image software, so you can clone an existing drive and move your operating system, applications, and files without a fresh install. Broad compatibility testing means the WD40EZAX integrates easily with most modern motherboards and storage controllers. A 2-year limited warranty provides added peace of mind for students, remote workers, and anyone who relies on a stable, always-ready computer.
