Product details

Increase laptop memory without compromising on performance with the unparalleled Western Digital Mainstream 2.5” Internal Hard Drive.

Memory boost

The WD Mainstream brings 320 GB worth of storage to your portable computing, allowing you to store a library of photos, videos and music.

It's also an ideal replacement or upgrade thanks to the Acronis True Image cloning software. Available for free from the WD Support Site, it makes light work of migrating your old hard drive's content, including the OS.

You can expect long-term reliability thanks to No Touch Ramp Load technology. This ensures the recording head never actually touches the disk media, significantly reducing wear and providing better protection when mobile.

High performance

Advanced power management provides low power consumption figures during everyday use, making the WD Mainstream a perfect match-up for your laptop.

You can buy with confidence as WD exhaustively test their hard drives on a multitude of platforms to guarantee they work on almost every conceivable platform.

Whether you're upgrading or supplementing, the WD Mainstream 2.5” Internal Hard Drive offers practical storage with peace of mind.
