With storage requirements becoming bigger and bigger all the time, WD have released a new 4 TB drive in their Red NAS range, and here is our review.


The new WD Red hard drives include a new version of NASware 2.0, which further improves drive reliability and protects data in the event of a power loss or disruption. WD Red hard drives also feature 3D Active Balance Plus, an enhanced balance control technology, which significantly improves overall drive performance and reliability.

Final Thoughts

The WD Red drive comes in a variety of sizes from 750 GB all the way up to the 4 TB version we are reviewing here.

This is one of the only 4 TB drives on the market today so if you need a lot of storage, and a good speed, and you plan on using the drive in your NAS then you really should look at this drive closely.

Also, this drive comes with a 3 year warranty. Now this may not seem like a major selling point to some people but believe me over the years I have had my fair share of failed drives and so it’s nice to know that anytime during that 3 year period WD will replace my drive if I have a problem – after all, you are spending a lot of money on it!

Every WD Red hard drive also comes with professional support services which includes a premium dedicated 24/7 support line. I didn’t need to use them during the course of this review, but having that option there if you need it is very good.

The performance of the drive is very good – especially as these drives are optimised and designed for use in a NAS, so if you want a reliable, good performing storage drive for your NAS then this will be right up your alley.

The WD website also has a NAS Compatibility Selector which enables you to check if these drives are compatible with your NAS – it’s certainly worth checking, although you will find all the usual suspects are supported.

The retail price for the 4 TB drive is around £169.99 but as usual look around for a good deal.
