Celebrating 10 Years of Acclaimed NAS Storage

This year, WD is celebrating 10 years since the launch of WD Red! The WD Red range was designed specifically for use in NAS environments to ensure optimal performance.

As part of the WD Colour Range, WD Red has become synonymous with trusted NAS storage and has grown to provide a wide array of options for your NAS, whether it’s for home, office or business use. WD Red Hard Drives now include options in a range of capacities from 1 to 22TB to store anything from family photos to the massive growth in data created by the business.

Recently, Western Digital also introduced WD Red SSDs, in both SATA and NVMeTM to provide high-speed capacity and caching to accelerate access to your data to keep pace with increasing system and network speeds.

So, whether it’s capacity or speed, WD Red have you covered!
