Product details

Keep your data safe with the huge 4 TB Western Digital WDBSLA0040HNC 3.5" Internal Hard Drive.

Superb performance

Designed for even the most demanding users, the WDBSLA0040HNC provides 4 TB of hard drive space which is perfect for storing photos, videos, important documents and much more. This high speed drive features a dual processor and a larger cache to provide the best read and write speeds.

The Dynamic Cache helps to improve performance by optimising cache allocations in real time, allocating more cache memory to the most demanding process, so you can read and write data quickly. For example, if there is much more read traffic than write traffic, the drive will automatically adjust the cache to reduce congestion.

Secure and stable

This hard drrive is designed for heavy use and employs rock solid architecture to protect the drive and the data stored on it. NoTouch Ramp Load technology helps to prolong the life of the disk. The recording head never touches the disk media, which helps to keep it running for longer, and can also protect it if your drive is dropped.

It's simple to upgrade your drive thanks to the WD Acronis True Image download, which lets you copy all of your data across to your new drive, so you don't have to sacrifice anything that's important to you.

WD performs tests on hundreds of systems and a multitude of platforms in its leading FIT Lab to give reliable and impressive longevity.

Give your PC the upgrade it deserves with the Western Digital WDBSLA0040HNC 3.5" Internal Hard Drive.
